CHANGES IN GGIR VERSION 3.1-?

  • Part 3:

    • Identification of daylight saving time days in the detection of the spt is improved as it had the risk to misclassify partial last days as daylight saving time.

    • In days classified as daysleeper, the window over which the fraction_night_invalid is calculated now also shifts to 6pm-6pm, as it used to report the nonwear within 12pm-12pm.

CHANGES IN GGIR VERSION 3.1-8

  • Part 4:

    • Parameter sib_must_fully_overlap_with_TimeInBed added to control whether sib should overlap fully with the start and/or end of time in bed to be considered sleep (default TRUE), this is consistent with functionality in the past. #1223

    • Handle unexpected combinations of sleep diary column names. For example, if only inbed and wakeup are available then treat these as the time in bed period, while if only sleeponset and outbed are available then these are treated as SPT window.

  • Part 5: Expand functionality for exploring possibility of nap detection, this includes the addition of new parameter possible_nap_gap.

  • Visual report: Added new visualreport that is automatically generated when visualreport = TRUE and intended to eventually replace the problematic legacy report. Add parameter old_visualreport to turn off the old visualreport generation. #1173

  • Part 4 + 5 + visualreport: If sleeplog has both reported sleeplog and time in bed process both. In part 4 we will still use one of the two but in the visualreport we display both. #967

  • Part 2: Add parameters nonwearFiltermaxHours and nonwearFilterWindow to give user the option to filter short lasting nighttime nonwear #1218.

  • Part 5 and 6: part6_threshold_combi when not specified now defaults to first threshold as specified for light, moderate and vigorous intensity respectively.

CHANGES IN GGIR VERSION 3.1-7

  • Part 3: Improved handling of DST, #1225

  • Part 2: Code revisions in preparation for expansion of functionality to better facilitate external function produced event data. #653 and #1228

  • Part 1: Ad-hoc csv file formats (read.myacc.csv functionality) now also excepts "UNIXmsec" as optional timestamp format. #1233

  • Part 5: Improved handling of partially available and non-available qwindow segments in the recording #1229

CHANGES IN GGIR VERSION 3.1-6

  • Part 6:

    • Add DFA functionality #839 (credits: Ian Meneghel Danilevicz and Victor Barreto Mesquita)

    • Add fragmentation metrics, same function as in part 5 but now applied at recording level #839

    • Circadian rhythm analysis now ignore invalid nights controlled with new parameter "includecrit.part6".

    • Circadian rhythm analysis now provides consistent results for both regardless of whether time series are stored with or without valid windows with parameter save_ms5raw_without_invalid.

  • Part 2 + 6: Revised and simplified IV and IS calculation which now ignores invalid timestamps and also comes with phi statistic (credits: Ian Meneghel Danilevicz). In part 2 we used to have 2 calculation, which is now replaced by just one and applied to all valid data points in the recordings. In part 6 this is repeated by for the time window as specified with parameter part6Window. Further, IVIS now uses argument threshold.lig as threshold to distinguish inactivity from active.

  • Part 2: Increase sensitivity clipping detection from 80% to 30% of a window. If the long epoch has more than 30% of its values close to the dynamic range of the sensor then it will be labelled as clipping.

  • Part 4: Now also has copy of part 5 variable ACC_spt_mg.

  • Part 5:

    • Moving LXMX from part 5 to part 6 as these are circadian rhythm analysis.

    • Omitted fragmentation metrics for spt window as not meaningful given that part 5 only focusses on valid daytime behaviours.

    • includenightcrit.part5 added to allow for controlling inclusion of windows in part 5 based on their amount of valid data during spt window. Default remains the same.

    • Fix incorrect usage of part 5 inclusion criteria testing, which used fraction as percentage.

CHANGES IN GGIR VERSION 3.1-5

  • Part 5:

    • Add parameters require_complete_lastnight_part5 to control whether last window is included if last night is incomplete. #1196

    • Handle sleeplog times beyond the end of the recording. #1206

    • Fixed minor bug in g.part5.addfirstwake causing the first wake is not correctly added when no SIBs are detected in between the start of the recorded and the algorithm or diary based estimate of wakeup time. #1198

    • Revise MM window definition in daylight saving time days, as it assumed fixed day duration of 24 hours #1211

  • General: GGIR version look-up in .onattach() no longer crashes when computer is offline, fixes #1203.

  • Reports: The calendar_date and filename columns in csv reports have been standardized, as %Y-%m-%d and the input accelerometer file name, respectively. #1197

  • Part 1: Reverse default value for nonwear_range_threshold as changed in 3.1-3 back to 150 as more research needed to support the change. #1172

  • Part 1: Tidied up code in internal function detect_nonwear_clipping.R to ease future reviews. #1212

  • Part 4: Undo changes to 3 line in g.part4 function from commit 3b9e2b7 (in between 3.1-1 and 3.1-2 release in June 2024) which broke functionality for handling sleep that starts before the double DST hour in the autumn and ends inside it. #1221

CHANGES IN GGIR VERSION 3.1-4

  • Part 3: Update threshold used for HorAngle to 60 degree, and auto-setting HASPT.ignore.invalid to NA when NotWorn guider is used. #1186

  • Part 4:

    • Fixed issue with merging sleeplog advanced format and acc data starting at midnight, #1188

    • When sleeplog column name is accidentally left empty generate error message, #1138.

    • Improved logging of what guider was used when using NotWorn and optional backup guider, #1156

    • Skip night in part 4 csv report if guider was NotWorn, #1156

  • Part 5: Fixed bug in g.part5.wakesleepwindows causing the first SPT window in a recording incorrectly to be defined from the first timestamp in the recording. For details see: #1192

CHANGES IN GGIR VERSION 3.1-3

  • Report part 4 and 5:

    • Fix bug at identifying days and nights specified in the data_cleaning_file #1168

  • Part 5: Fix bug in addition of first wake-up time if not present #1179

  • Part 2: Correctly skip MXLX calculation when it cannot be calculated, which caused error when trying to use the output. Fixes #1180

  • Part 1: Add parameter nonwear_range_threshold to control range threshold for nonwear detection, this used to be a constant. And default changed to 50mg. #1172

  • Part 4: Improved error message when a sleeplog timestamp is not in expected format. #1184

  • Part 3: Fix handling of recordings with only 1 midnight that start before 4am. #1160

  • Part 3 and 4:

    • Revise NotWorn algorithm to work with both count and raw data with varying degrees of nonwear. Further, when parameter HASPT.algo is set to NotWorn then a second guider can now optionally be specified in case the accelerometer unexpectedly worn by the participant. #1089

    • Fix bug in detection of waking up after noon, referred to as daysleeper. #1165

  • Part 5: Behaviour parameter includedaycrit.part5 changed for values above 1, these are now interpreted as minimum number of valid waking hours during waking horus of a day. If you prefer to keep old functionality then divide your old value by 24 #1050.

  • Part 1:

    • Improved readability and maintainability of the code #1027

    • Improved processing speed for Axivity .cwa, GENEActiv .bin, and Movisens files

    • Made sure that g.readaccfile() reads timestamps in the correct timezone, configtz, for all monitor types

    • Note: there will be small differences in both metalong and metashort metrics calculated by this GGIR version, compared to prior versions. This is due to small improvements in the management of timestamps, calibration coefficients, and input data block boundaries.

  • Part 3: If argument sensor.location is set to hip then use longitudinal axis detected in part 2 instead of estimating it again with a different algorithm #1024

  • Part 5: If argument sensor.location is set to hip then store and use longitudinal angle and possible other angles in part 5 time series instead of anglez #1024.

CHANGES IN GGIR VERSION 3.0-3

  • Part 2: Fix bug where data_quality_report.csv contained incorrect filehealth[...] values whenever some of these values were supposed to be blank #1003

  • Part 1: Fix bug where on machines with GMT timezone and R >= 4.3.0, for GENEActiv .bin files, the starting timestamps of M$metalong and M$metashort were truncated to midninght #1000

  • Part 5: Reverting decision to prohibit segmentDAYSPTcrit.part5 to be c(0, 0). The default remains unchanged and documentation now only emphasizes the downside of using c(0, 0). #980

  • Argument documentation: Fixing series of typos (thanks to Pieter-Jan Marent for pointing them out)

  • Part 5: Fix bug in recently added functionality for studying overlap between sibs and self-reported behaviours #989.

  • Part 1:Enable use of temperature data in adhoc-csv format throughout GGIR #991

  • Part 6: Added new part 6 with for now only Household co-analysis and Cosinor analysis.

CHANGES IN GGIR VERSION 3.0-0

  • Part 1 and 2: Change default value for nonwear_approach to "2023" which labels the entire window as nonwear if conditions are met. This instead of only the middle 15 minutes as is the case for "2013" setting. Further, setting "2023" now uses a 5 Hertz version of the signals for non-wear detection, for clipping detection the code uses the original signal.

  • Part 2: Move cosinor analysis code to its own function in order to ease re-using it in both part 2 and part 6.

  • Part2: Expand cosinor analysis with R2

  • Part 2: Arguments hrs.del.start and hrs.del.end when combined with strategy = 3 and strategy = 5 now count relative to start and end of the most active time window as identified. #905

  • Part 5: Change default for segmentDAYSPTcrit.part5 from c(0,0) to c(0, 0.9) and now prohibiting the use of c(0, 0) as it gives biased estimates. We knew this, but some users started using the default without attempting to understand it, by which it seems necessary to force a sensible default. #940

  • Add contributing guidelines for github.io documentation #923

  • Part 5: Added optioned "OO" to argument timewindow, which defines windows from sleep Onset to sleep Onset #931

CHANGES IN GGIR VERSION 2.10-4

CHANGES IN GGIR VERSION 2.10-3

  • Part 1: Fixed minor bug in ismovisens that failed when datadir started with "./" #897

  • Part 5: Now able to assess overlap between self-reported naps and nonwear with sustained inactivity bouts in order to facilitate research on nap detection. Fixes #687

  • Part 5: Time series now also exported if recording only includes one night, even though this is not sufficient for the main part 5 analyses. #894 Further, the time series now also come with lightpeak (LUX).

  • Visualreport: Bug fixed extracting the numeric value of the days to exclude in g.plot5 #879

  • Part 1: Fixed minor bug to keep calibration data in the data quality report after re-running parts 1 and 2 with overwrite = TRUE and backup.cal.coef = "retrieve" #896

  • g.intensitygradient enabled to handle absense of data.

  • tidied up some of the redundant or even confusiong information printer to the console

CHANGES IN GGIR VERSION 1.7-1

  • Fixed order of Nbouts output in g.part5 was not consistent with bout duration.

  • Functionality added to read AX3 Axivity csv files that have the following characteristics: Raw data in g-units, not resampled, and with timestamps stored in the first column.

  • Fixed bug that caused the date of the last measurement day in part5 output to be one day ahead if argument dayborder=12.

  • Part5 struggled to process measurements with more than 40 days, now fixed.

  • g.getstarttime can now also handle dates in Actigraph csv-file headers that are dot separated, e.g. 20.05.2016, before it only handled 20-05-2016 and 20/05/2016.

  • Report part 4: Count of available nights with accelerometer data fixed

  • Report part 4: NA and NaN values replaced by empty cells like in other reports

  • Intensity gradient analysis added to part2 output according to Rowlands et al. MSSE 2018, doi: 10.1249/MSS.0000000000001561

  • Documentation on part4 output variables improved.

  • Providing incorrect value of sleeplogidnum in part4 should now provide a more informative error message

CHANGES IN GGIR VERSION 1.6-0

  • Fixed timezone dependency of g.analyse (affected only order of columns), g.part5 (affected time detection), and consequently test_chainof5parts.R

  • Read functionality for Actigraph csv files speeded up by replacing read.csv by data.table::fread

  • Argument qwindow is now able to handle input vectors longer than 2 and will derive all part2 variables for each time window that can be defined from the values of qwindow, e.g. value =c(0,8,24) will analyse the windows: 0-8, 8-24 and 0-24 hour.

  • Argument L5M5window deprecated because argument qwindow now defines the window over which L5M5 analysis is performed.

  • Argument winhr is now reflected in g.analyse/g.part2 output variable names, previously this variable name was hardcoded as L5M5, even if winhr was not 5.

  • Part2 output variable names updated to be more consistent in structure and more explicit about the timewindow over which they are calculated. The variables that were calculated over the full recording (using diurnal normalization) now have the extension "fullRecording", this in contrast to the variables that are only calculated from measurement days with 'enough' valid data.

  • Fixed calculation of N valid WEdays and Nvalid WKdays in part2 that was wrong since version 1.5-21. It counted all days and did not exclude days with insufficient amount of data.

  • Fixed warning message in test of g.part5.

  • output variable acc_timeinbed renamed to acc_SptDuration to avoid confusion with terminology used in supporting papers, which are about SPT (sleep period time) detection and not about time in bed detection.

  • output variable acc_dur_noc renamed to acc_SleepDurationInSpt to improve clarity of variable name relative to acc_SptDuration

CHANGES IN GGIR VERSION 1.5-24

  • Variable names ENMO accidentatly disappeared from g.analyse output in 1.5-23, this has now been reversed.

  • Fixed issue in g.part5 in handling the last day of measurement when using 'MM' windows and dayborder not equal to 0 (midnight) sometimes resulting in the last day longer than 25 hours.

  • Fixed error message in g.part5 that occurs when calculating L5M5 when day is shorter than L5M5 time window.

CHANGES IN GGIR VERSION 1.5-23

  • Unit tests speeded up by using a smaller test file.

CHANGES IN GGIR VERSION 1.5-21

  • g.part5 is now able to generate summary from all measurment days (thanks Jairo).

  • MM results in g.part5 now correctly stores onset and waking for single date per row.

  • Various checks added to g.part4 to ensure measurements in all shapes and size can be processed.

  • minor improvements to documentation g.part5

  • size of example data and vignette images reduced to reduce package size

CHANGES IN GGIR VERSION 1.5-18

  • Improved handling of day saving time in g.part3 and g.part4 within the two nights in a year when the clock changes (DST was already correctly handled in the rest of the year)

  • Algorithm HDCZA is now the default algorithm to use, if a sleeplog is used and an entry is missing for a particular night.

  • pdf generation in part 3 is now optional (argument do.part3.pdf), this may be useful for slightly speeding up data processing as it takes a few second to generate the plot.

  • test added for g.getbout function.

  • bug fixed in timestamp recognition for object timebb in function g.part5

CHANGES IN GGIR VERSION 1.5-17

CHANGES IN GGIR VERSION 1.5-16

  • Codecov testing added and badge added to the README file

  • Functions added to create dummy accelerometer file (csv) and dummy sleeplog (csv), needed for testing

  • Bug fixed in g.wavread to recognize .wav extension file header for files with alternative header size

  • Default IVIS_epochsize_seconds parameter updated from 30 to 3600

  • g.part1 messages on the consolo are now condensed printing only the number of the blocks loaded separated by spaces rather than new lines

  • Split g.part5 function into multiple smaller functions

  • Replace hard-coded "Europe/London" in g.part5 by desiredtz, to make the function work for users outside the UK

  • Data frame output from g.part5 is now tidied up by removing empty rows and columns generated

CHANGES IN GGIR VERSION 1.5-1

  • Removed teLindert2013 metric, because it was not used and not verified

  • Split g.getmeta function into multiple smaller functions

  • Added IS and IV variables to g.analyse (still in explorative version)

  • bug fixed related to wav file read errors

  • function g.cwaread added (credits to E. Mirkes) for reading Axivity .cwa-format data. g.shellGGIR will automatically use this function when input data has .cwa extension

  • bug fixed related to for GENEactiv starttime recognition which was introduced in version 1.2-11

CHANGES IN GGIR VERSION 1.2-11

  • Bug fixed related to MVPA variable. The bug was a result of the updates in version 1.2-10

CHANGES IN GGIR VERSION 1.2-10

  • Changed function argument 'mvpa.2014' into 'bout.metric' across the package in preparation for a central defintion of bouts for future GGIR version which will not only provide bout calculations for MVPA but also for inactivity. Further, I added function g.getbout to improve transparency about the bout calculations

  • Updated documentation for function g.analyse to clarify different bout metric definitions

  • Improvements to the functionality to only process specific days from a long accelerometer file using the argument selectdaysfile

  • Timestamps are now in ISO 8601 format. I have updated the code such that it can still handle old timestamp format, but newly processed files will produce timestamps in the ISO 8601 format. The practical difference is that it will include a numeric timezone indicator.

  • Bugs fixed in data selection in g.getmeta function. In the old code it tended to drop the last 30-45 minutes of a file.

  • Added more optional features to be generated by g.getmeta, including rolling medians of the acceleration signals.

CHANGES IN GGIR VERSION 1.2-8

  • Updated documentation for function g.analyse to clarify different mvpa bout definitions

  • mvpa.2014 = TRUE turned back on again (was disable in last version)

CHANGES IN GGIR VERSION 1.2-7

  • mvpa.2014 TRUE/FALSE was swapped, FALSE is now the default

CHANGES IN GGIR VERSION 1.2-6

  • Modified warning message in relation to the change in MVPA bout defintion

CHANGES IN GGIR VERSION 1.2-5

  • Accelerometer non-wear time is now also reported in the output of part 4

  • Part 1 is now able to only process specific days of a measurement via argument selectdaysfile. This is useful when measurement lasts for a week and the participant is instructed to only wear the accelerometer on one or two specific days.

  • Argument mvpa.2014 and closedbout added to function g.analyse. The calculation of MVPA (moderate and vigorous physical activity) has been available since 2014. This calculation has been improved, but the user has the option to continue using the old calculation.

CHANGES IN GGIR VERSION 1.2-2

  • Bug fixed in the loading of data files with (very) large amounts of data

  • Bug fixed in starttime allocation for measurements starting in the 15 minutes before midnight

CHANGES IN GGIR VERSION 1.2-1

  • Literature reference for sleep detection updated

  • Argument backup.cal.coef now with improved feedback if something goes wrong

  • Report generation for part 4 much faster now

  • Bug fixed in part 4 in assignment of dayname when a person sleeps during the day

  • g.shell.GGIR now capable of handling minimal input argument specifications

  • Console output from part 3 and 4 more compact now

CHANGES IN GGIR VERSION 1.2-0

  • Package expanded with functions for detecting sleep (g.part3 and g.part4)

CHANGES IN GGIR VERSION 1.1-5

  • Additional bugs fixs related to dealing with csv-format data from the Actigraph accelerometer brand

  • g.part2 now also stores its output as milestone data just like g.part1. This to facilitate parallel processing of large amounts of data files on clusters.

  • The orginal report generation functionality in g.part2 has now been moved to shell function g.shell.GGIR because part3, 4 and 5 which are scheduled for later this year will combine milestone data from multiple analysis parts. It therefore, is more logical to control all report generation from the top level in the function hierarchy (g.shell.GGIR).

  • g.part1 now comes with the option to provide backup calibration coefficients in case auto-calibration is unsuccessful. This function is primarily designed for studies with short lasting experiments.

  • g.part2 now has the option to export epoch values to a csv-file. Note that these same epoch values are also stored in the .RData milestone file from part2. The export option is mainly to ease access to epoch level data outside the R environment.

  • g.shell.GGIR now offers the option to overwrite previously generated milestone data with variable 'overwrite'. The default setting (FALSE) is still to skip previously analysed files, which is intended to avoid having to do the same analyses twice after an interruption. However, overwriting previously generated milestone data could be useful when modifications are being made to the input arguments.

  • g.shell.GGIR now offers the option to record the folderstructure in which an accelerometer file is located, especially useful for studies where accelerometer files are stored hierarchally in line with the study design.

CHANGES IN GGIR VERSION 1.1-4

  • Additional bugs fixs related to recognising data format in Actigraph data

  • Angle variables are now extracted based on 5 second rolling median as opposed to 501 sample rolling median

CHANGES IN GGIR VERSION 1.1-3

  • Package expanded with functions: g.part1, g.part2, and g.shell.GGIR. These shell functions should help movement scientists to utilize the package without too much prior knowledge about R

  • Additional bugs fixs related to recognising data format in Actigraph data

  • Package expanded with axis angle metrics

  • Package expanded with metric for replicating teLindert2013 counts, see g.getmeta

  • Package expanded with metric ENMOa, see function tutorial g.getmeta

CHANGES IN GGIR VERSION 1.0-6

  • Bug fixed related to recognising date format in csv-file header from Actigraph accelerometer brand

  • Literature reference added to function g.calibrate

  • function g.getmeta expanded with argument 'chunksize'

CHANGES IN GGIR VERSION 1.0-4

  • Implemented functionality for csv-fromat data from GENEActiv and Actigraph. It seems to work for the test files I have, more testing may be necessary

  • Cleaned up some of the NaN and NA output to aim for consistent annotation of missing data

CHANGES IN GGIR VERSION 1.0-3

  • Fixed bug in modified g.analyse in version 1.0-2

CHANGES IN GGIR VERSION 1.0-2

  • Expanded g.analyse with estimates of time spent in moderate and vigorous activity (a construct popular among physical activity researchers)

  • Re-named a number of variables in the output from g.analyse to be more friendly for re-use in stata or sas. The majority of variable names are now shorter and do not include spaces, dots or commas

CHANGES IN GGIR VERSION 1.0-1

  • Fixed Linux-Windows sensitivty in g.getmeta. Certain damaged files can only be read with mmap.load set to FALSE in package GENEAread. Function g.getmeta in GGIR catches this problem and turns mmap.load to FALSE if necessary. This catch worked well under Linux, but not for R in Windows. I have now fixed this

CHANGES IN GGIR VERSION 1.0-00

  • Added examples

  • Expanded documentation for function g.analyse

  • Fixed bug in extraction of starttime that caused the starttime to be truncated to 00:00:00 in a fraction of measurements.

  • Fixed bug in extract of temperature in function g.calibrate

  • Deleted three explorative variables that were only extracted in g.analyse if argument doangle was set to TRUE in function g.getmeta. A number of bugs and the lack of referable journal publications made me decide to remove these variables while working on them. I intend on re-releasing these variables during the course of 2014. Please contact me if this causes you problems

CHANGES IN GGIR VERSION 0.6-17

  • This was the first version
