You can preprocess multiple participants in a batch or individual participants, depending on how you invoke the preproc-sess command.
Batch processing
Batch processing requires a sessid file containing the session names (i.e., the names of all the Freesurfer folders) for all your participants. The sessid file can be called anything you wish, and is simply a plain text file with one folder name on each line. For example:
chris_subjects.txt: FS_T1_501 FS_T2_501 FS_T1_505 FS_T2_505
When doing a batch, you call using the -sf switch:
preproc-sess -sf <sessidfile> -df <srchdirfile> [options]
e.g.,
preproc-sess -sf chris_subjects.txt -surface self lhrh –fwhm 6 -per-run –fsd bold
If the -df switch isn't provided (it doesn't seem to be mandatory) then it uses a default directory (possibly $SUBJECTS_DIR, or possibly your current working directory) to start in.
Individuals
Preprocessing individuals works pretty much the same, except you do not require a sessid file. Instead, you provide it with the name of one of the session folders, and use the -s switch, rather than the -sf switch:
preproc-sess -per-run -fwhm 6 -surface self lhrh -fsd bold -s FS_T1_501
