'lh_G_Ins_lg&S_cent_ins_volume' and 'lh_G_insular_short_volume'
by Christophe Destrieux 22 Nov '18

22 Nov '18

External Email - Use Caution Hi Rujing Sorry for the late answer. These 2 labels correspond to the insula The insula is divided by the central sulcus of the insula (S_cent_ins_) into long insular gyri (G_Ins_lg) and short insular gyri (G_insular_short). Since the cortex lining the central sulcus of the insula was quite small, it has been grouped together with the the long insular gyri ( 'lh_G_Ins_lg&S_cent_ins_volume’) If you are interested in the volume of the whole insula you need to add the volumes of these two anatomical classes. For a complete list of anatomical classes and explanations on their anatomical meaning see : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937159/ Best Christophe Destrieux, Unité iBrain UMRS INSERM U1253, Université de Tours https://ibrain.univ-tours.fr/ <https://ibrain.univ-tours.fr/> Service de Neurochirurgie et Laboratoire d'Anatomie - Faculté de Médecine - 10 Bd Tonnellé - 37032 Tours - France tel (33) 2 47 36 61 36 - fax (33) 2 47 36 62 07 > Le 21 nov. 2018 à 17:12, Bruce Fischl <fischl(a)nmr.mgh.harvard.edu> a écrit : > > you are getting very popular! > > > ---------- Forwarded message ---------- > Date: Wed, 21 Nov 2018 14:30:13 +0800 > From: charujing123 <charujing123(a)163.com> > Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> > To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> > Subject: [Freesurfer] 'lh_G_Ins_lg&S_cent_ins_volume' and > 'lh_G_insular_short_volume' > > > External Email - Use Caution > > Hi, what is difference between and 'lh_G_insular_short_volume'.

How to automate recon-all command for multiple subjects
by Vivek Sharma 22 Nov '18

22 Nov '18

External Email - Use Caution Hi, I'm using freesurfer to generate head surfaces using MRI file. I want to execute recon-all command for number of subjects, but unable to run it. The script I'm using is: for i in `cat *subs.txt*` do recon-all -s $i -all -qcache done subs.txt contains the name of folder that contains .nii file. The scripts ends with the following error: ERROR: no run data found in /cblhome/vivek/freesurfer/subjects/sub-CC110033_T1w/mri. Make sure to have a volume called 001.mgz in /cblhome/vivek/freesurfer/subjects/sub-CC110033_T1w/mri/orig. If you have a second run of data call it 002.mgz, etc. See also: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Conversion Linux cblhost 4.4.0-83-generic #106~14.04.1-Ubuntu SMP Mon Jun 26 18:10:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Please let me know how I can run recon-all for multiple subjects. Thank you. -- Vivek Sharma Mobile: +919953582034 Skype: vivek.sharma1015

Corrupted T1 file (?) but segmentation look fine
by Anneliis Sartin-tarm 21 Nov '18

21 Nov '18

External Email - Use Caution Hello all, I have been running into a curious problem with a couple brains (8 out of 150 seem to have this problem) running through the recon-all pipeline. Upon loading brainmask.mgz, T1.mgz, and corresponding white matter and pial surfaces in Freeview, my colleague and I received an error that T1.mgz failed to load. Segmentation and parcellation seemed to run smoothly and accurately, however, the size of the T1.mgz file was 0. Assuming the file had been corrupted somehow (our server through which we run recon-all and store our data has tons of available memory), we reran the brains affected. Upon loading up the same re-run surfaces, T1.mgz loaded into the GUI as white, washed out voxels, displaying no brain at all. The size of this file is large, as well as all other surface and volume files. Curiously, the brainmask file seems normalized/stripped fine and surfaces displayed over the T1 look accurately segmented. I attached a screenshot displaying the T1.mgz file and surfaces that I'm referring to. I have a few concerns and questions. Because T1.mgz doesn't seem to be necessary for downstream manual editing and processing, can we proceed as normal, only displaying and using the brainmask file to make edits? Will our surface and volume metrics export properly without a usable T1 file? Lastly, any clues to how this might have occurred are welcomed. It seems like the mri_normalize step is the culprit, although the nu.mgz files corresponding to these brains seem normally sized.

nu_correct ERROR (FreeSurfer v6)
by Korom, Marta 20 Nov '18

20 Nov '18

External Email - Use Caution Dear FreeSurfer Developers, I have the most recent version of FreeSurfer installed on a MacOS Mojave (10.14) and as I was running recon-all, I received the following error message: "Assertion failed at line 742 in file templates/CachedArray.cc nu_estimate_np_and_em: crashed while running volume_stats (termination status=256) nu_correct: crashed while running nu_estimate_np_and_em (termination status=256) ERROR: nu_correct Darwin Martas-MacBook-Pro.local 18.0.0 Darwin Kernel Version 18.0.0: Wed Aug 22 20:13:40 PDT 2018; root:xnu-4903.201.2~1/RELEASE_X86_64 x86_64 recon-all -s plc0061 exited with ERRORS at Tue Nov 20 22:32:15 EST 2018" I reviewed many threads on the same error message, but none of them were solved. I have the same version of FreeSurfer on two other MacBooks (with older versions of iOS) and both work fine. I ran fixup_mni_paths as it was suggested on multiple threads and nu_correct, as well and I got the following message: "nu_correct nu_correct, version 1.12.0 Usage: nu_correct [-help] [options] in.mnc out.mnc" Any thoughts on what the problem might be and how it could be fixed? Could this be an iOS compatibility issue?

Bonferroni correction of 2spaces or 3spaces
by YAN Chao-Gan 20 Nov '18

20 Nov '18

External Email - Use Caution Dear freesurfer experts, I have a pretty naive question but would like to confirm. When we use --3spaces option in multiple comparison correction, does that mean we set the Cluster-wise threshold (cwp, not Cluster Defining Threshold or Cluster Forming Threshold) to 0.5/3=0.0167 for lh. Similar cwp at 0.0167 for rh and subcortical? In addition, if we use "--cortex" to restrict the calculation on cortex only, where can we find the corresponding mask or label file for cortex?
