External Email - Use Caution Hi Douglas, Yes, the file (/lustre/group/p00355/REST_Beijing_SCZ/Freesurfer/fsaverage/surf/rh.white) exists, I can view it in Freeview and have read permissions. I had recently tried downloading this patch: https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/ as I was equally having issues with make_average_subject and had found this forum post: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg57023.html Not sure if the problem might then be with mri_surfcluster.bin ? Thanks again, Colleen

calculated cortical thickness from segmented binary gray matter and white matter images from other software
by yuanchao.zhang8＠gmail.com 23 Sep '18

23 Sep '18

External Email - Use Caution Dear experts, Is there any way I can calculate the cortical thickness based on gray matter and white matter binary images from other software. I mean I have a image in native space with white matter voxels labelled as 10 and gray matter voxels labelled as 5. Is there any way I can manage to calculate the cortical maps from this image using freesurfer? Thanks a lot! Best, Yuanchao Zhang yuanchao.zhang8(a)gmail.com

External Email - Use Caution Hello Freesurfer Developpers, I'm attempting to make a study specific template using all of my subjects as input using the make_average_subject command, but am receiving the following error: Building hash of lh white Building hash of lh pial Building hash of rh white Building hash of rh pial Loading aseg from /lustre/group/p00355/REST_Beijing_SCZ/Freesurfer/average_v2/mri/aseg.presurf.hypos.mgz ASeg Vox2RAS: ----------- -1.00000 0.00000 0.00000 128.00000; 0.00000 0.00000 1.00000 -128.00000; 0.00000 -1.00000 0.00000 128.00000; 0.00000 0.00000 0.00000 1.00000; mghRead(mri/norm.mgz, -1): could not open file ------------------------- Labeling Slice relabeling unlikely voxels in interior of white matter Segmentation fault (core dumped) Linux wbic-cs-5 3.16.0-6-amd64 #1 SMP Debian 3.16.57-2 (2018-07-14) x86_64 GNU/Linux recon-all -s average_v2 exited with ERRORS at Fri Sep 21 11:11:25 BST 2018 I've attached here the full log file. I read in this forum: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg57030.html to try installing the following patch: https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/ and had asked our computing support team to install it before the current run of make_average_subject, so the error seems to be happening despite the patch. I would greatly appreciate your suggestions for resolving the error. Thanks very much, Colleen

Best way to update Freeview
by Maksimovskiy, Arkadiy 21 Sep '18

21 Sep '18

Dear Experts, Updating Freeview came up as a potential solution for a problem in a different thread, so I posting this as a separate issue, since the question stands on its own. I am currently using “Freeview Version 2.0” – Build Jan 19 2017. This version came with the Freesurfer 6.0 package, but from browsing the wiki, it seems that this version is out of date and requires a separate update. When I attempted to update Freeview, by clicking on “freeview_osx.tar.gz” using the link at Step 2 for Mac (located at this page: https://surfer.nmr.mgh.harvard.edu/fswiki/UpdateFreeview) I get the following error message: “The requested URL /pub/dist/freesurfer/freeview/freeview_osx.tar.gz was not found on this server.” I was wondering if there might a different way to obtain the latest Freeview version. Thank you for your help, arkadiy
