Can someone advise how I fix this loop?

I am using a MatLab based interface for processing EEG files collected from 59 subjects. The below code works but only for 1 file and I have 59 files I want a result from. sFiles filters the files stored in this interface and correctly returns 59 files. However, sStudy only returns a result for the first file. How do I run a loop on the below code so I can get 'n' for all 59 files? I would like to get the result 'n' for each file along with the subject name (in sFiles as SubjectName).

sFiles = bst_process('CallProcess', 'process_select_search', [], [], ...
    'search', '(([name CONTAINS "resample"]))');

sStudy = bst_get('Study', sFiles.iStudy);

DataMat = in_bst_data(sStudy.Data(i).FileName);

n = numel(DataMat.F.events(3).times)

Hi,

That would be somewhat in this way:

for ii = 1:59
sFiles(ii).iStudy = bst_process('CallProcess', 'process_select_search', [], [], ...
'search', '(([name CONTAINS "resample"]))');
 
sStudy = bst_get('Study', sFiles(ii).iStudy);
DataMat = in_bst_data(sStudy.Data(ii).FileName);
n(ii) = numel(DataMat.F.events(ii).times);
end

Hi Sulaymon

Thank you for your reply. I ran it and got the below error.

Unrecognized function or variable 'iStudies'.

Error in bst_get (line 515)

if ~isempty(iStudies)

Error in Working_file (line 5)

sStudy = bst_get('Study', sFiles(ii).iStudy);

[Sulaymon Eshkabilov]

In that case, you can edit: sFiles(ii).iStudy to be sFiles(ii)

Note that it is all blindly written by me without much knowledge about your data files.

Thank you

Is that working ok, now? if so, hit accept the answer. Thx.

Hi Sulaymon,

That was the right approach thanks. I had to change the variables.
