By mistake, some of our participants were given a keyboard during a task, in which they shouldn't respond. Some of the participants pressed the key once, creating an event with code 1. This creates issues with the create_sots function, particularly with "contains(event_code{k},allcond{i}.OnsetID)", as contains() apparently does not work for numeric objects. This might be only an issue in our particular situation, but could possibly also affect studies which either have similar anomalies or have numeric event codes in some instances.

Matlab recommends not to use textread anymore (see snippet from create_sots below). Textscan would be an alternative. Another option would be to use readcell() to separately extract the variable names for the logfiles and the data extract the data. This way, it might be possible to subset the important variables by their names and not with complex formatting, which might go wrong if stimulus onset files are not identical (e.g., when they have a column for participant IDs at the beginning or not).

[event_type,event_code,event_time] = textread([logfile.folder,filesep,logfile.name],'%*d %s %s %d %*s%*s%*s%*s%*s%*s%*s%*s%*s','headerlines',IgnoreHeaderLines)

I couldn't get the create_sots function to run when using the input argument "free". When using the "BIDS" input argument, I ran into error code #15. It worked well when removing the following code chunk:

        filename = [subject,write_ses,LogID,'.log'];
        logfile = dir([logdir,filesep,filename]); 
        % if isempty(logfile)
        %     filename = [prefix,filename];
        %     logfile = dir([logdir,filesep,filename]);
        % else
        %     out{dum,:} = 'Logfile not found.\nWarning #15\nContinue with next session.\n';
        %     return
        % end

Maybe I don't understand something important, but in my case this code chunk first successfully correctly creates the objects "filename" and "logfile", then tests if they were successfully created, and returns an error message if they were successfully created , skipping to the next subject.

My data structure:
In my logfiles folder, each participant has a subfolder, containing only one logfile. The folders are called e.g. 1234 for the first subject, without the "sub-" prefix.
