Dear Freesurfer experts
Happy Holidays! I have a subject with two highres fMRI scan sessions. 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.
Thanks Mona
