Hi Janosh,

cross sectional processing should be OK, but longitudinal is more difficult. The subject id is passed to the base and stored there (both in a text file and also in the filename of the corresponding transformations from base to each time point). Also the long directory filename is made up from the cross filename and base "cross.long.base". To avoid problems you should remove the base, rerun it and also recreate the longitudinal time points again (theoretically it would be sufficient to rename the longitudinal directories accordingly as the base should not change at all, only some of the filenames -- not tested!).

Best, Martin

Hi all,

I wonder whether I can rename subjects after processing has been done and do further processing or stats on them without running in any problems.

From reading http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg26244.html, it seems as if the name of the subject folder under which everything else resides is the only marker and renaming it should be sufficient.

But it seems the subject name is written in other places (http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg19285.html). Is this only a problem for de-identification or could it also cause other problems if the subject folder name and the name that is used elsewhere in the tree don't match.

Are there special considerations regarding the longitudinal workflow?

Thanks,

Janosch
