Error loading custom labels
by Catherine Tallman 04 Sep '20

04 Sep '20

External Email - Use Caution Hello, After running mri_vol2label I created a custom label named lh.parahippocampal.label. When I try to load the label onto lh.pial, I receive the following error: "Could not load label from <path>". The file is saved within the path folder itself. I was wondering if there is a workaround for this issue? mri_vol2label --c mri/aparc+aseg.mgz --id 1016 --l label/lh.parahippocampal.label Thank you, Catherine -- ------------------------------------------------ Catherine Tallman, M.A. Graduate Student CNS Laboratory of Memory and Brain University of California, San Diego

autorecon2, error MRISreadCurvature:
by James Hartzell 03 Sep '20

03 Sep '20

External Email - Use Caution Hi When running recon-all autorecon2, on a single subject with (Macbook Pro 10.15.6 (19G2021), freesurfer-darwin-macOS-7.1.0-20200511-813297b) it handles the rh.curv without a problem, but for the lh kicks out this error: /Users...$subj.../surf \n mris_curvature_stats -m --writeCurvatureFiles -G -o ../stats/lh.curv.stats -F smoothwm $subj lh curv sulc \n Toggling save flag on curvature files [ ok ] Outputting results using filestem [ ../stats/lh.curv.stats ] Toggling save flag on curvature files [ ok ] Setting surface [ $subj./lh.smoothwm ] Reading surface... [ ok ] Setting texture [ curv ] Reading texture...error: No such file or directory error: MRISreadCurvature: could not open /Users/$subj./surf/lh.curv ***WARNING!*** Some error has occurred while reading 'lh.curv'. This might be due a vertex incompatibility between the surface 'lh.smoothwm' and curv 'lh.curv'. You might be able to correct this by re-running 'mris_make_surfaces' on this dataset. Skipping this (and any remaining) curvature files. Any measurements / calcuations that depend on the curvature file will be skipped. ************* Note /Users/$subj./surf/lh.curv does exist in the subject's surf folder. I ran it twice just to be sure. I don't find an answer for the problem in the freesurfer list. Any guidance will be much appreciated! Cheers James Hartzell, PhD (2x) Donostia-San Sebatián, Spain

how to calculate Euler number
by C.P.E. Rollins 03 Sep '20

03 Sep '20

External Email - Use Caution Dear Freesurfer Developers, It is not clear to me how to calculate the Euler number. Using mri_segstats reports something like: Computing euler number orig.nofix lheno = -18, rheno = -20 orig.nofix lhholes = 10, rhholes = 11 However, I had understood from previous comments that the Euler number should be around 2. I'm wondering which of the above numbers I could report. Thanks, Colleen

tkregister2 deprecated for FS7.1?
by Zeng, Victor (BIDMC - Keshavan - Psychiatry) 02 Sep '20

02 Sep '20

Hi FS devs, I am following https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview? as a tutorial to fix the bad talaiarch file I have. I know that tkmedit is deprecated, but I was wondering if tkregister2 is too. If so, I was wondering what software I would use (or commands, I assume using freeview) since that page still refers to tkregister2.

External Email - Use Caution Hi Freesurfer group, For some reason, I have to use the left and right brain stem separately. I wonder if there is one way to have a midline, to cut the brain stem into Left and Right? Many thanks, Mengxing

Re: [Freesurfer] Freesurfer hippocampal error
by Emily K Clarke 02 Sep '20

External Email - Use Caution Hi Douglas, Could you point me to the documentation about creating hippocampal files outside of recon-all? I’m not familiar with running this method outside of recon-all since I’ve typically followed the ENIGMA hippocampal pipeline. Best, Emily
