Greetings!

I am trying to do the average (By trial group-subject Average) with the EEG recordings. For the same, I have kept all the subjects in the Process1 tab. Also, for these subjects, I have the PSDs' and the Envelope Connectivity measure. image

Before run process "Average > Average files", I used a process to 'select the file using the tag',

then a bug appears (screenshot is attached below)

Kindly let me know if I'm doing something wrong.

I added a test that should prevent this error to happen:

Update Brainstorm to get this fix.

I'm not sure what you are doing is very optimal. Before going further, I recommend you follow the resting state tutorial:
