Re: [Freesurfer] mris_fix_topology stops with two T1-s
Many thanks Bruce, I will choose the best one in this case. The command line was: recon-all -s B_06 -qcache -measure thickness -all (I already had copied by hand the /mri/orig/001.mgz and 002.mgz) Just in case I repeated the process with the original files, but I had exactly the same results. This was the command line: recon-all -i /home/glerma/glerma/freesurfer/subjects/BERTSO_MRI/BS3_06/58153751 -i /home/glerma/glerma/freesurfer/subjects/BERTSO_MRI/SESION2/06_BERTSOLARI_IEA/54336388 -s B_06c -qcache -measure thickness -all thanks!

Including structurals from different days may not work as you may have large differential distortions due to differences in e.g. shimming, gradient nonlinearities, etc... that will preclude an accurate motion correction. Certainly it failed in this case. cheers Bruce On Fri, 10 Aug 2012, Garikoitz Lerma Usabiaga wrote: Thanks for the answer Bruce, it is still running, so I killed the process. When using two individual structural images separately, the recon-all process was OK. When I tried to use both structurals, I can check that the T1.mgz has some strange distortions (please check image attached). When it is ok using two structurals (different days, same subject)? In this is case, is there something we can do to fix it or should be use just one of them?

The time it takes is square in the convex hull of the largest defect, so that can take a long time. A 45K defect is too big and typically means something is dramatically wrong, like the cerebellum or skull is attached. cheers Bruce On Sun, 5 Aug 2012, Garikoitz Lerma Usabiaga wrote: Hi FS experts, I've run recon-all -i file -s subject -qcache -measure thickness -all to: - 18 subjects, session 1 T1 - same 18 subjects, session 2 T1 and everything went well.

[Freesurfer] Averaging overlays/labels across subjects
Dear Surfers, I have (non-fMRI) .w format surface overlays/labels, computed at the smoothwm surface in each individual subject, in 25 subjects. FS5.1 recon-all has been run for all T1 images. I already managed to convert all individual surface overlays into the surface space of one of the subjects (or fsaverage) using mri_surf2surf, and in the process also converted the format from .w to .mgh (as I understand .w is pretty much legacy). Now, I would just need to compute an average across these overlays. I would greatly appreciate any suggestions which FS tools to use for this. Thank you in advance! (In case it matters, the overlays are E-field estimates, with a numerical value given for each vertex point. Also each overlay has only one time point.)
