I am using freesurfer version 7.4.1, and would like to incorporate the recently introduced synthstrip and synthseg functions into my recon-all command, if that's possible. From this archive message (https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg75148.html) it seems that adding the -synthstrip option enables synthstrip; however, I don't see this as an option in the recon-all documentation (https://surfer.nmr.mgh.harvard.edu/fswiki/recon-all) nor as a command line option for recon-all.

Assuming that both synthstrip and synthseg can be used in recon-all, would the command need to look something like this:

I'm adding the --no-csf synthstrip option based on this comment (https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg75172.html).

I should also note that I'm performing a longitudinal analysis, so this specific recon-all pertains to the cross-sectional portion of the workflow. 

Thanks,

Dan
