I want to concatenate the two sessions which I guess is the same as combining them statistically. Please note that it's all done in "self" space not fsaverage.

Are you computing contrasts between the two sessions or you just want to combine them statistically? On 1/2/2020 10:07 AM, Nasiriavanaki, Zahra wrote: I need to concatenate the two sessions. We scanned the subjects twice with the same task. I need to see the maps for each session separately and also together.

Attached you can see an image, showing how I organized the sub-folders. I preprocessed the bold1 and bold2 and then copied the preprocessed files to "bold from both sessions" folder. I ran selxavg for bold1 and bold2 seperately and it went well. However, when I ran selxavg for "bold from both sessions" folder, it gives the below error. Could you please let me know what the problem is?Also if you have a better suggestion for how I should organize my subfolders/analysis, I appreciate that.
