freeview crash

External Email - Use Caution To whom it may concern: I am a graduate student major in neurosurgery at Fudan University. Nowadays, I am learning to use freesurfer in order to segment brain sulci and gyri. However, in some situation, the freeview will crash. For example, when I load “lh.area” surface, the freeview crashed. The error code is “0x02000148”. The information of system is list below: OS Version: Mac OS X 10.15.5 (19F101) Report Version: 12 Bridge OS Version: 4.5 (17P5300) Model: MacBookPro15,1, 8 processors, 8-Core Intel Core i9, 2.3 GHz, 32 GB There are some other operations to the freeview will lead to the crashes. But the load of surface is a more common one. Could give me any advice in solving the problem. I look forward to hearing from you soon. Thanks so much Yusheng Tong

License Agreement for re-distribution
by Ezequiel Mikulan 22 Mar '21

22 Mar '21

External Email - Use Caution Hi All, I've developed an open-source software for MRI pseudonymization that uses Freesurfer so I wanted to check that I'm correctly handling the licenses. In Freesurfer's License Agreement it says that: "If you distribute Software (as defined below) downloaded from FreeSurfer, all of the paragraphs of Part B of this Agreement must be included with and apply to such Software". It is not clear to me if we should copy the relevant part into our license or if it is ok if we add a text file in the software with Freesurfer's license. In other words, should Part B be included inside our license or inside the software as a file? How should I proceed? Thanks, Ezequiel

Some brain area missing after running recon-all
by Stef Meliss 22 Mar '21

22 Mar '21

External Email - Use Caution Dear FreeSurfer Experts I am using FreeSurfer on my anatomical data to use segmentations and parcellations in my fMRI analyses in AFNI. After reviewing the output from recon-all -all (FreeSurfer version 6.0.0), I noticed that one subject is missing some occipital areas in the output (e.g. aparc+aseg.mgz). Please see attached for a screenshot of the output from freeview -v mri/brainmask.mgz \ mri/wm.mgz:colormap=heat:opacity=0.4 \ -f surf/lh.white:edgecolor=yellow \ surf/lh.pial:edgecolor=red \ surf/rh.white:edgecolor=yellow \ surf/rh.pial:edgecolor=red \ surf/rh.inflated:visible=0 \ surf/lh.inflated:visible=0 From what I read in the information on troubleshooting the output, I understand that manual editing is necessary to fix this – is this correct? I have verified that the missing areas are included in the brainmask as well as aseg.presurf. I am not sure though how to determine whether I am dealing with a segmentation error or a normalization error or maybe even a combination of both. If you could give me some pointers on which steps to take, that would be highly appreciated. Many thanks in advance for your help. Best regards, Stef

Freesurfer 6.0.0 Container & MCR
by Ursula Tooley 22 Mar '21

22 Mar '21

External Email - Use Caution Hi Freesurfer experts, I’m trying to use the official FS 6.0.0 container from Dockerhub on a new HPC (for consistency with previous pipelines), and got the error below about not finding the Matlab Compiler Runtime in the container. I have worked around it by explicitly binding the mcr on the HPC to the container with “-B /cbica/software/external/matlab/mcr/v711/:/opt/freesurfer/MCRv80”, but is this the expected behavior? Or is there some issue? My understanding was that one of the advantages of mcr was that you could include it in containers and distribute compiled code, so was surprised to find this come up. Thanks in advance, Ursula --- Ursula Tooley Ph.D. Candidate Neuroscience Graduate Group University of Pennsylvania she/her/hers utooley(a)gmail.com 202.413.5627

Freesurfer 7.1 recon-all -long exits with erros
by Yakupov, Renat /DZNE 22 Mar '21

22 Mar '21

External Email - Use Caution Dear Freesurfer developers, I am trying to run the longitudinal processing pipeline of our data on our HPC cluster (SGE based) and it crashes at the 3rd step - generating the longitudinal runs. The exact command is 'recon-all -long tp1dir basedir -all'. There is no error message on the screen, it just says that it exited with errors. The recon-all.log file has no error information either, other than the statement that it exited with errors. It seems to have stopped after mri_nu_correct.mni step and looking further it looks like it crashed at the beginning of orig_nu step, since orig_nu.log has this error message: /usr/bin/time: /dev/stdout: Not a directory Please see attached log files. Additional information: Freesurfer version: freesurfer-linux-centos6_x86_64-7.1.1-20200723-8b40551 uname -a: Linux compute-0-2.local 2.6.32-504.16.2.el6.x86_64 #1 SMP Wed Apr 22 06:48:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux lsb_release -a: LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.6 (Final) Release: 6.6 Codename: Final What is interesting is that running it on the headnode directly without qsub works fine. The headnode has the same OS and tcsh versions. In my rather poorly informed opinion, it looks like fs_time is the culprit. For a quick fix, is it safe to assume that using fs_time from Freesurfer 6 wont affect the processing pipeline in any way? Thank you! Best regards, Renat.

-hires vs -conf2hires in 7.1.1.
by Alexopoulos, Dimitrios 21 Mar '21

21 Mar '21

External Email - Use Caution Does the hires flag still generate segs at the native hi resolution and place surfaces on the 1mm volumes, whereas conf2hires generates volumes at 1mm but places surfaces on the hires images? Which option is recommended and why?
