Can you run

mri_info --dim Sess01/bold/rtopyTR2.lh//mask.nii.gz

for each of your subjects and send us the result?

Hello Freesurfer developers,

I am trying to concatenate session files of different subjects using isxconcat-sess. I am not really sure why " INFO:trgsubject is self, this will fail unless all sessions are the same subject" pops up as I understand this is what isxconcat-sess is meant to do, and I used --subject fsaverage in some tries. I am not sure if there is something I am doing wrong, or the problem is coming from the "//" in the output lines. When I took out either Sess01 and Sess02 from the list to be sure it wasn't a problem specific to it, I got the same error.

Below is the error output.
