Error loading data

[W-Jason]

Hi,

I've installed FASST and the dependent sofware spm12 which is the latest version.
I am getting an error when I try to load the data.
I am loading the .mat file.
Please let me know what's the issue

Hi Jason(?),
The important information is on the 2nd line of the error message:
File "F:.....mat" doesn't contain SPM M/EEG data.
So it looks like your data and not in the right format... Could you double-check how your data were imported into SPM format? Did you use SPM "import" function or relied on the specific import function in FASST?
Best.

Thank you for your answer!
I want to use the cICA algorithm in this toolbox.But i do not know the input data format.
I try to use cICA algorithm,but this problem occurs.

Could you help me solve this issue.
Thank you!

Hi Jason,
Hard to say without a look at the data. The algorithm is complaining that the data are "too noisy"... cICA can be sensitive to "other arterfacts" present in the EEG signal, beyond the cardiobalistic artefact. This is probably why it's not happy here.
2 things to try:

• could you visually check your data? And ensure that the gradient artefact was properly cleaned up and that there is not too much 'other bad stuff' in the signal?
• try out a simpler cardiobalistic artefact correction approach, such as AAS. And check what's coming out of it. AAS is used as a 1st approximation for cICA, so if AAS doesn't work at least partially, cICA is doomed...
  HTH!
