If volumes, get a registration matrix using bbregister, then run mri_vol2surf specifying fsaverage as the target subject.

Re: [Freesurfer] How to find the difference between to different fMRI datasets?
Thanks Douglas! 1 - I have two functional files per subject (.mgh). Is it possible to insert two files per subject in mris_preproc? In my former functional analysis I haven't concatenated my data using a FSGD-file when running mris_preproc. 2 - Can you calculate the difference between two functional data sets (on the fsaverage) before starting the group analysis stream? E.g. by subtracting the files?

[Freesurfer] How to find the difference between to different fMRI datasets?
Dear FreeSurfer team, Thank you for all your help so far! I would like to visualize the difference between two fMRI data sets. Data set1: Cortical activation during movement of a finger. Data set2: Cortical activation during movement of a finger different from the first finger. How can i perform this operation?
