segfault using brainstem module from dev version
by Vincent Beliveau 20 May '16

20 May '16

Hi list (and Eugenio), I've ran the brainstem module from the dev version on some data processed with FS v5.3. The module created some great segmentations of brainstem but when taking a closer look at the log file, there is 2 seg faults which occur when calls to mri_robust_register are made, with the following output (full log attached, see line 319 and 371): /data1/vbeliveau/software/freesurfer-Linux-centos4_x86_64-dev-110516/bin//mri_robust_register: line 3: 36835 Segmentation fault mri_robust_register.bin "$@" /data1/vbeliveau/software/freesurfer-Linux-centos4_x86_64-dev-110516/bin//mri_robust_register --mov imageDump.mgz --dst /indirect/data1/vbeliveau/atlas/proc/MR/recon_final/f5249_GD/tmp/BS_T1based//BS-DE-binaryMask_autoCropped.mgz -lta trash.lta --mapmovhdr imageDump_coregistered.mgz --sat 50: Segmentation fault mv: cannot stat ?imageDump_coregistered.mgz?: No such file or directory I'm curious about how is this affecting the overall process, as otherwise everything appears to be working smoothly.

Question about group analysis
by Josh Gray 20 May '16

20 May '16

Hello, I've got a very basic question related to group analysis. If I want run a correlation of voxels in the cortex with a variable *controlling *for another continous variable, how do I do this. I know how to run them both in a GLM simultaneously by coding the matrix 0 1 1, however, how do I look at the first variable after controlling for the other? Here is an example of my current fsgd input (I want to control for income): GroupDescriptorFile 1 Title MyTitle Class Class1 plus blue CLASS Class2 circle green SomeTag Variables impulsivity income Input subjid1 Main 10 100 Input subjid2 Main 20 200 etc. -- Graduate Student Psychology Dept. - Clinical Program Experimental & Clinical Psychopharmacology Laboratory University of Georgia

Specifically, I have a .label from tksurfer and I would like to report this label on subj orig.nii.gz ----Messaggio originale---- Da: stdp82(a)virgilio.it Data: 20-mag-2016 10.36 A: <freesurfer(a)nmr.mgh.harvard.edu> Ogg: [Freesurfer] MASK.label from fsaverage to volume in subject space Hi list, to trasform a MASK.label (created by tk surfer) from surface to volume is correct to use: 1. mri_surf2surf to register the mask from fsaverage to subj space2. mri_surf2vol to report the label (subj space) to volume (subj space) Thanks.

I made the necessary changes to the white matter, and when I ran recon all the changes with the voxels showed up, but there was no change to the contour lines. In order to change the gray matter volume, I can¹t find the changes I already made on the white matter (the picture with green control points). If I am able to see the changes I made to the white matter, I can utilize the control points to modify the segmentation. Also will this impact the gray matter volume as well as per your previous response to my question. Thanks, Gaurang
