[Erppcatoolkit-support] Problem merging .set files

[Ines B. <ine...@ps...>]

Hello,

First of all thank you very much for the nice toolkit! I just started to use it to do PCA analysis.

I am trying to load eeglab .set files. I have 26 different files, corresponding to the averages of 26 different participants for one condition. As far as I understood the tutorial, for the PCA analysis, the files need to be merged into a single file. In order to do that, I:
1) click in the single cell files option; and
2) write 1:26 on the subject and 1:26 on the cell box;

This doesn't work and I get the following error message:

Index exceeds matrix dimensions.
Error in ep>readFiles (line 9913)
            theSubs{theFile}=sessionFiles{theFile}(subPos);
Error in ep (line 3090)
        readFiles(theHandles,importFormat,dataType);
Error while evaluating uicontrol Callback

However, if I try to load the data of just 10 participants (whatever 10 files I select) it does work out...
Am I doing something wrong?

Thank you very much in advance!
Ines
