help with SAMSEG
by Alberto Del Cerro Leon 05 May '21

05 May '21

External Email - Use Caution Hello Freesurfer team, my group is interested in using the SAMSEG tool to evaluate white matter lesions in MCI patients. We would like to use a personalized atlas for the measure. We suppose that we need to use the flag --atlas but we don`t know if we need a generic atlas or we need an atlas at each subject' spaces. Thanks in advance for your help.

Freesurfer version 7 reconall -autorecon2-wm error
by Jewelia K. Yao 05 May '21

05 May '21

External Email - Use Caution Hi Freesurfer Developers, I am trying to run reconall -autorecon2-wm using Freesurfer version 7 after making some minor edits to the wm.mgz file. I've tried it on multiple subjects and still get the same error (recon-all.log attached) when mri_fill starts to run: reading segmented volume aseg.presurf.mgz removing CC from segmentation Looking for area (min, max) = (350, 1400) area[0] = 1276 (min = 350, max = 1400), aspect = 0.46 (min = 0.10, max = 0.75) no need to search using seed (127, 124, 151), TAL = (1.0, 23.0, 4.0) *** Error in `mri_fill': double free or corruption (!prev): 0x0000000001c65070 *** reconall -autorecon2-wm runs well with Freesurfer version 6, but since the data was run through reconall with version 7, I was hoping to to use it for autorecon as well. I couldn't find any similar errors (specific to version 7) in the list. Does anyone know if this error is specific to version 7 and if there's any way to troubleshoot? Thanks! Jewelia

Error with mris_convert
by バキット・ムダシル 05 May '21

05 May '21

External Email - Use Caution Hi, I manually made annotation files on an inflated surface of 40 subjects. The labels that makes these annotfiles are 13 in total but not present in all subjects every time, some can be missing depending on the brains surface morphology. I made the ctab files manually in the label folder in eluding an unknown label in the first line. I tried to convert one of the annotfiles into gii format and got the following error: mris_convert --annot $SUBJECTS_DIR/spl_01/label/lh.par.annot $SUBJECTS_DIR/spl_01/surf/lh.white ~/Desktop/spl_01/lh.par.gii reading colortable from annotation file... colortable with 14 entries read (originally none) Segmentation fault: 11 What this error exactly means, and how I can solve this issue. Thanks Mudathir

Re: [Freesurfer] Freeview slow on CentOS 8 Stream

External Email - Use Caution Hello Torkil, Not sure what version of Freesurfer you are using, but if it’s an older release, it could be interesting to compare the performance with one of the latest development builds (not a release) from https://secure-web.cisco.com/11eosYMqxQIzJXYwfskbMMIPybJKGeVS7FnO….  There’s an archive and RPM for CentOS7 and an archive for a CentOS8 build. - R.

Error 3d normalization pass 1 of 2 white matter peak

External Email - Use Caution Dear Freesurfer experts, I am running recon all on a T1 image that already gave me many problems. After I solved the last one (adding control points in white matter) I finally got a new error. The command I run is: echo "cd $PWD; ./recon_all_sub056.sh" | qsub -N "reconall_sub056" -l walltime=48:00:00,mem=150gb. Error is: 3d normalization pass 1 of 2 white matter peak found at 110 Cannot allocate memory Linux dccn-c047.dccn.nl 4.19.94-300.el7.x86_64 #1 SMP Thu Jan 9 16:15:13 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux 150gb is more memory than I ever used while running recon all on other data, so I doubt that adding more memory will help. Please could someone give me any hint on how can I solve this error?

QA in longitudinal processing
by Malo Gaubert 03 May '21

03 May '21

External Email - Use Caution Hello FreeSurfer developers, I am trying to apply longitudinal processing on T1w MRI data for two timepoints (~8 months between the two TP) in adolescents in order to perform vertex-based analyses. I am following the online tutorial here for the preprocessing: https://secure-web.cisco.com/15SLKllO1EVTB4t08TfZPIkp1fVCDUdF94m0DqoL4seAFO… Thus I launched the creation of BASE followed by the LONGITUDINAL. Everything went well for recon-all for these 3 steps. Now, I want to do the QA on the data and I have two questions regarding this QA: 1/ For one subject, for the two timepoints, the white and pial surface are entering in the left lateral ventricle as displayed in figure 1 (session 1 of the subject; cross-sectional), while the aseg is fine (this area is considered as Lateral ventricle, see figure 2 attached). What correction could I apply for this case ? 2/ For some subjects, there is a small shift between the pial of the two sessions (or the white; see figure 3=display of the norm of my norm and pial/white for the two timepoints (long)) and/or some weird/non straight lines for pial or white (see figure 3, especially between temporal pole and the rest of the brain). What could be the error in this case? Could it be related to some bad quality of T1w images? 1) FreeSurfer version: freesurfer-linux-centos7_x86_64-7.1.0.tar.gz 2) Platform: Ubuntu 18 (Virtual Machine on remote server) 3) uname -a: Linux ubuntu18-cbrain-042020 4.15.0-135-generic #139-Ubuntu SMP Mon Jan 18 17:38:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Any help would be appreciated.
