Neural-profiling

Author: Michael Bornholdt / November 2021

This repository relates to my work done at the Carpenter-Singh lab at the Broad institute of MIT and Harvard. Within the summer of 2021, I develop a protocol for robustly and scalably quantifying (profiling) cellular states from images using deep neural networks. The results and conclusions can be in the resulting Master thesis document /Final_Masterthesis_Bornholdt.pdf.

Experiment IDs

Each experiment has a unique ID which refers to the day on which it was run, eg, 1028. The Training_index.md file holds all information on which experiment was run on which parameters and which what data In /training/index you can find all the index files for the different subsets of data. The /training/runs folder holds all profiles and training output from each experiment.

Description of the repository content

basline/

The first part of the project gathers CellProfiler profiles from the LINCS repository and compares them. A general overview of the data and of the subselection is found here! If you want to compare metrics with my data, you need to follow the steps in baseline/02_analysis/02_clean_data.ipynb.

pre-trained/

The two pre-trained nets are compared here and create the baseline for the trained neural networks. The best pipeline for deep learning features is determined.

training/

All experiments live here. The experiments are different models trained with different hyperparameters and data. A full analysis of the resulting profiles can be found in the training/results/ folder.

chtc/ and docker/

These folders hold important scripts for setting up and running DeepProfiler on a server.

hit_k

This folder contains the development code of the hit@k metric. Now on Cyto-eval/

LINCS_example_data/

A small subsection of the LINCS data allows to test and learn DP. Alternatively used example data from DP Github.

Experimental data on S3

Important random things

  • Some information in this repository may be old since the DeepProfiler versions changed midway through the project
  • The single cell crops of all 18 million cells within the LINCS subsection can be found on S3: s3://cellpainting-gallery/cpg0004-lincs/broad/workspace/deep_learning/outputs/1017_sc/
  • If you can't reach Michael Bornholdt, try to reach Shantanu Singh.
