It is pretty old, but maybe it still works

Yes, I have attached a link to the previous correspondence from the Freesurfer mailing archives here:
MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg68977.html

For more context, I have functional data in an .nii.gz format that was pre-processed in FSL, but I need help converting it into functional left and right hemisphere surface maps in FreeSurfer for an input to a toolbox. Hope this makes sense.

My bad, I meant to say surfaces. Right now the files are downsampled on 
fsaverage4 space and I need to now split it into the respective left/right 
hemispheres. For context, these are .nii.gz files currently. Is there a way to 
easily do this in Freesurfer?

Best,
