mri_cvs_register quit for mris_resample: Command not found
by Cong 18 Oct '16

18 Oct '16

Dear freesufer experts I’m learning DTI image process according to steps in FsTutorial/ Diffusion_DtiIntegration. In Spatial Normalization I need create a .m3z morph file through mir_cvs_register. I used command mri_cvs_register --mov subjectname --template cvs_avg35. But it always stop for mris_resample: Command not found. I run freesurfer v5.3.0 in a MacBook Pro. Two log file in cvs folder are attached. Could you give me some advice? Thanks very much. Best Wishes Cong Chen

mri_nu_correct crash
by Burkhard Maess 18 Oct '16

18 Oct '16

hello Freesurfer developers, during the recon-all (autorecon1) processing, it seems that the mne_nu_correct procedure does not always manage to finish successfully. I have searched the net, found a question in the mailing list, which seemed to be similar, but no answer (http://www.bic.mni.mcgill.ca/pipermail/minc-users/2015-November/004205.html) Our status file shows, that we had sometimes runs which were completed without errors. Maybe, we should not have started the recon-all a second time. It would be very great if you could help with further hints. For instance, could we remove a file or several files to roll back to the situation when it worked? all the best, Burkhard .....................

Generating aparc statistics that only correspond to a masked region
by Brandy Riedel 17 Oct '16

17 Oct '16

Hello Freesurfer's, I would like to generate the standard aparc.mgz statistics, but only for ROIs or for segments of an ROI that fall within the bounds of a mask. I've created the mask I want to use, have label files that correspond to the mask, have a masked version of the aparc.mgz, but I can't seem to figure out this final step. I was planning to use mris_anatomical_stats but none of the adjustments I've tried have yielded output different from the standard aparc stats. Any help would be appreciated! Thank you!

Re: [Freesurfer] Quantifying volumes
by Damien MARIE 17 Oct '16

17 Oct '16

Hi, Just adding a word about the e-mail of ma colleague Josue. What he meant is that he extracted volumes for exactly the same ROI (a merging of destrieux labels of Hechl’s gyrus, Heschl's sulcus and planum temporale) using 1- a .curv file of this ROI, mri_binarize and mri_segstats or 2- a .label file of this ROI and mris_anatomical_stats. We get a different volume output (ratio of difference between the 2 methods = approx. 2.5, similar to mean thickness I would say…), so we would like to understand what is happening exactly. Using the method 1, it’s actually a surface measurement we get no? Would that be possible to convert a .cuvr file to a .label file ? Thank you and best, Damien Josue Luiz Dalboni Da Rocha Wed, 12 Oct 2016 07:26:32 -0700 Dear Doug, Thank you very much for your advice! We get to extract results for the volumes from a ".curv file encoded ROI" using your recommended command lines (mri_binarize and mri_segstats ), but unfortunately the results are much smaller (around 3 times) than when we extract total gray matter volumes from a respective ".label file encoded ROI" using mris_anatomical_stats . Example: Volumes from a ".curv file encoded ROI" using your recommended command lines (mri_binarize and mri_segstats): Subject1 = 1090 Subject2 = 1181 Subject3 = 713 Subject4 = 1230 Volumes from a respective ".label file encoded ROI" (mris_anatomical_stats): Subject1 = 3497 Subject2 = 3786 Subject3 = 2268 Subject4 = 3491 Are the volumes extracted from a ".curv file encoded ROI" (using mri_binarize and mri_segstats) an estimation of the total gray matter volumes? Why these values are differing that much?

FreeSurfer on MP2RAGE
by Daniel Ferreira 16 Oct '16

16 Oct '16

Dear all, We have been working quite extensively with Freesurfer over the years. We are now starting to collect a new large cohort and we are about to decide which T1-weighted sequence to use, MPRAGE or MP2RAGE (Siemens 3T Prisma, headcoil 20 Chanel). When we visually inspect the images we think there is a better contrast between GM and WM in the MP2RAGE over the traditional MPRAGE sequence. Both sequences seem to produce good Freesurfer output, but the cortex tend to be a bit thinner with MP2RAGE, possibly due to the better contrast, but we can of course not be sure of this. Freesurfer have always produced nice results with the MPRAGE sequence and the MPRAGE flag seems to work well. Do you think this flag will work as well on MP2RAGE? Of course it is difficult to say but we wonder if you have any opinion on which sequence to use? Thank you very much, Best regards -- Daniel Ferreira, PhD.
