using synthsr with HCP Pipeline
by KennethSPrice 03 Aug '23

03 Aug '23

External Email - Use Caution Hello all, I am currently struggling through the HCP Pipeline! I want to use clinical scans processed with synthsr in the HCP Pipeline. 1.) Is this even possible? 2.) Is there a way to get a T2 output with synthsr? 3.) In lieu of the HCP Pipeline, could you use SythSR scans with the HCP Database to do a normal group analysis? Thanks, Ken

Please see the capture below: [cid:a7289c63-1b2b-407c-9dec-a9ff5e082daa] Fig.1 Under-segmentation of white and pial surfaces still not fixed after running the command with the flags -autorecon2-cp -autorecon3 for the subject [cid:baf96016-01d2-4d50-ac8e-ce6067c1dec6] Fig.2 The same image for the subject, with the visible wm. The tutorial <https://secure-web.cisco.com/1eFs9sHrAZSKhe4nUQhj-OHr9PCuaQnsYS1AVa0FxCl5k_…> from the FsTutorial indicated that adding control points to the white matter area only. Moreover, the pial surface expends from the white surface. Thus, it is not possible to add control points on the cortex. Would somebody can help with fixing such error, please? Thank you very much!

External Email - Use Caution Hi, I am running freesurfer/7.3.2 and had an issue with freeview sudden termination. The error message is *sub-002/label/aparc.annot.ctabMRISreadAnnotationIntoArray: vertex index out of range: 538980362 i=2020300A, in_array_size=132205* *annot file: /fs04/wr47/Project/Data/NIFTI/Freesurfer7.3.2/sub-002/label/aparc.annot.ctab* *terminate called after throwing an instance of 'int'* It happened when I tried to load any annotation. I can load pial surfaces. I worked in a cluster computer if that helps. Thank you, Kind regards, Jacob -- *Jacob Bunyamin* PhD Student *Department of Neuroscience* Central Clinical School, Monash University 99 Commercial Road Melbourne VIC 3004 *E:* jacob.bunyamin(a)monash.edu

External Email - Use Caution Hello FreeSurfer Developers, I have installed FreeSurfer v6.0.0 in my MacOS 12.6.7 but I got Freeview crashed due to PETSC error (which has been fixed in FreeSurfer v7.1.1). For the consistency with my previous work, I do not want to upgrade to Freesurfer V7.x in my MAC. I updated the latest freeview from this website: https://secure-web.cisco.com/1GU54Krzar0viM1rYGXBq6dM7Sopf4ca6PYKueDS2-Ie8D… freesurfer-macOS-darwin_x86_64-dev-freeview.tar.gz 2023-07-29 08:52 37M After updating the Freeview, it works for me but whenever I load a pial surface, I got this error message: error: mincRead(): error reading volume from file /Applications/freesurfer/mni/bin/../share/mni_autoreg/average_305_8_dxyz.mnc I'm not sure this is serious or just relating to the rendering. Could anyone tell me how to fix this? 1) Freesurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0 2) Platform: MacOS Darwin 12.6.7 3) freeview: mincRead(): error reading volume from file /Applications/freesurfer/mni/bin/../share/mni_autoreg/average_305_8_dxyz.mnc 4) FreeSurferColorLUT.txt: see attached Thanks, Ha

mris_preproc error: cannot allocate memory
by MANSSOUR Wassima 01 Aug '23

External Email - Use Caution Hello FreeSurfer Developers, I'm conducting the Surface Based Group Analysis explained on the tutoriel (https://secure-web.cisco.com/1_YynvwS-dkAnt9HfkAib_JfSy9UZxarfHbzK2t54zb7qC…) but I keep getting the error: "Cannot allocate memory" while running the mris_preproc command. I'm using the data of 355 subjects stored on an external hard drive, and a pc of 23G RAM, but it stops at the 334 subject. I've already tried with a windows and mac of 16G RAM and got the error, so moved to the other one but still getting the same issue. Does anyone have any thoughts on how to trouble-shoot this? or any other alternative solution to run the mris_preproc on all the subjects? FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0 Platforme: Debian 3.16.7 Thank you for your help, -- Wassima MANSSOUR Master Student at INSEA Rabat M2SI - Information Systems & Intelligent Systems IMRB intern-France wmanssour(a)insea.ac.ma<mailto:wmanssour@insea.ac.ma> wassima.manssour(a)u-pec.fr<mailto:wassima.manssour@u-pec.fr>
