Hi Laura,

For any study, it is essential that you process all of your subjects on the same operating system. Even though the same FS version is used, there will be underlying system-level differences that may lead to small inconsistencies across your linux and mac results.

Also, are your recons dying after printing “build stamps do not match”? That message should just be a warning and not force a recon-all exit unless REQUIRE_FS_MATCH is enabled (it’s not by default).

Best

Subject: [Freesurfer] ERROR - build stamps do not match

        External Email - Use Caution        

Hi,

I have been processing datasets on my Linux on v6.0 but have recently been made to work from home where I only have access to a Mac.  I’m getting the following error message when continuing the editing on datasets that were already started on my Linux:

INFO: FreeSurfer build stamps do not match

Subject Stamp: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c

Current Stamp: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c

A few questions:

Is it feasible to override this error message for subjects that I have already started processing since they are both using v6.0?

I have about half of my data set already fully processed using a Linux – if I start processing the second half from scratch using my Mac, can I eventually combine the 2 parts of the dataset for comparison?

If I use a mix of Freesurfer builds on different data sets, can I still process data sets from the same subject using the longitudinal stream?

Thanks,

Laura Danielian
