[Re] medial wall label in Freesurfer 6
by Sofia Rodriguez Penuela 29 Nov '17

29 Nov '17

Hi, User M del Mar and me belong to same investigation group, so the problem is common. We have 116 subjects and we detected this trouble. However, we tried to repeat the make_average_subject command using a subgroup (only 60 subjects) and label files were correctly created. Maybe, number of subjetcs is the key. Nevertheless, with Freesurfer 5.3 we haven't this problem, no matter number of subjects. Best, Sofia -- Sofía Rodríguez Peñuela, Técnico de Laboratorio.

Re: [Freesurfer] Surface-based kernel operations
by Victor Montal Blancafort 29 Nov '17

29 Nov '17

Thanks Bruce and Doug! Bruce, I think the option of the sphere is the one that better fits my needs, since I need to perform conv operations + derivatives. How should address this issue? I am not very familiar with sphere files (nor metric tensors) and do not know how to open/where to find those files. Thank you once again! Bests, Victor M

TRACULA and the IFOF
by Juergen Haenggi 29 Nov '17

Dear TRACULA experts I am wondering wheter someone has already implemented the tractography of the inferior fronto-occipital fascicle (IFOF) into TRACULA? if yes, we are interested in this implementation.

error in segmentHA_T2.sh
by Cong 29 Nov '17

29 Nov '17

Dear freesurfer experts I am trying segment hippocampal and amygdala subregions in dev version(freesurfer-i386-apple-darwin11.4.2-dev-20171024), the segmentHA_T1.sh works well. However, when I try to add a T2 propeller sequence it doesn’t work. I am sure the T2.nii file is in mri folder, and this T2.nii file works well in 6.0.0 version for segmenting hippocampal subregion. I pasted the wrong scripts, could you tell me what’s wrong? Thanks!

Surface-based kernel operations
by Victor Montal Blancafort 28 Nov '17

28 Nov '17

Dear Freesurfer experts, I would like to preform several operations in surface files using spatial kernels (i.e mean value in a 3x3 grid, nearest neighbour value, etc). In summary, perform operations in the surface such as a 2D matrix/image. Is it possible to do it with Freesurfer? I tried to open the surfaces using Python and Matlab, but as far as I am concerned, the vertex orders does not follow any "continous" or topological order. Any insight would be very appreciated. Thanks in advance! Victor M

MacOS Sierra 10.12.5 dyld lazy symbol binding error
by Kelly Martin 28 Nov '17

28 Nov '17

Hi all, I have Freesurfer version freesurfer-i386-apple-darwin11.4.2-stable6-20170119 installed on my MacOS Sierra 10.12.5 environment, and am experiencing similar library issues to what others have reported. I have tried previously offered suggestions to update and test MacPorts, as well as $ sudo -E fs_update. I am trying to run a Connectome Workbench command, but the errors I am receiving involve incompatibilities with the Freesurfer libraries. I was however able to run recon-all without a problem. Does anyone have a recommendation on how to proceed? This is the error: dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address Referenced from: /Users/username/Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib Expected in: /usr/lib/libSystem.B.dylib Thank you, Kelly -- Kelly Martin Graduate Student Interdisciplinary Program in Neuroscience Georgetown University

Tracula / 0 slices processed in Bedpostx before queuing post processing stage
by Anna Mynick 28 Nov '17

28 Nov '17

Hi, I’m having difficulty making BedpostX work on non-tutorial data per the tutorial located here: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/RunningTracula <https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/RunningTracula> The preprocessing has worked without errors, but now that I’m using BedpostX, the output is producing: subjectdir is {subject's directory}/dmri Making bedpostx directory structure Queuing preprocessing stages Queuing parallel processing stage 0 slices processed Queuing post processing stage Obviously, it shouldn’t be going straight from 0 slices processed to the post processing stage. I’m running the command directly (i.e. bedpostx {subject's directory}/dmri ), and when the process is done ( it ends in 25 seconds) the dmri folder has files that are in the format data_slice_00**.nii.gz and nodif_brain_mask_slice_00**.nii.gz. I’ve also tried running the command: trac-all -bedp -c $TUTORIAL_DATA/diffusion_tutorial/dmrirc.tutorial on a cluster, which produces the same output. Has anyone else had this issue? Thanks for any help, Anna

ERROR: fast_sexavg3() failed\n
by Christina Pressl 28 Nov '17

28 Nov '17

Hi Freesurferteam, For some of my subjects I get an error when I try to perform my analyses, because the mcprextreg file is missing. It is not apparent to my why this file is missing for some of my subjects, while it is there for all the other subjects. Also, there is one subject for which the file is missing in one out of three bold runs. For the other two runs the file was perfectly generated. Could you please help me solving this issue? Thank you very much. Best regards, Christina

neonatal brain
by Dijkshoorn, A.B.C. (Aicha) 28 Nov '17

28 Nov '17

Dear all, I want to build my own neonatal control reference template (n=35)to investigate cortical thickness measures and compare these to neonates with a rare type of bleeding. I read that freesurfer uses an adult reference atlas, but that a neonatal-infant (0-2y) is being made/has been made. Is this new pipeline yet available in freesurfer? And can I build my own reference template in FREESURFER without interference from an adult brain template?

Merging two groups
by Ramesh Babu 28 Nov '17

28 Nov '17

Hi, I have done recon-all -all processing for 2 groups in separate subjects directories. I want to put all subjects in one dkirectory. Should I copy paste all subject’s folders in one directory or is there any others steps to merge? Thanks in advance RB
