Re: [Freesurfer] ERROR - build stamps do not match
by Hoopes, Andrew 25 Mar '20

Hi Laura, For any study, it is essential that you process all of your subjects on the same operating system. Even though the same FS version is used, there will be underlying system-level differences that may lead to small inconsistencies across your linux and mac results. Also, are your recons dying after printing “build stamps do not match”? That message should just be a warning and not force a recon-all exit unless REQUIRE_FS_MATCH is enabled (it’s not by default).

I’m getting the following error message when continuing the editing on datasets that were already started on my Linux: INFO: FreeSurfer build stamps do not match Subject Stamp: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c Current Stamp: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c A few questions: Is it feasible to override this error message for subjects that I have already started processing since they are both using v6.0? I have about half of my data set already fully processed using a Linux – if I start processing the second half from scratch using my Mac, can I eventually combine the 2 parts of the dataset for comparison? If I use a mix of Freesurfer builds on different data sets, can I still process data sets from the same subject using the longitudinal stream? Thanks, Laura Danielian

recon-all : command not found
by Koustav Chatterjee 25 Mar '20

25 Mar '20

External Email - Use Caution Dear Sir/Madam, Hope this mail finds you well, considering the present pandemic scenario across globe. I have installed FreeSurfer in my PC successfully and I have been following tutorials and freesurfer wiki to learn the basics of it. I have an image with .nii extension saved in usr/local/freesurfer/subjects directory in ubuntu. I wanted to use recon-all command for preprocessing the image.nii. root@ubuntu:/usr/local/freesurfer/subjects# recon-all -s kctest01 -i (the input file.nii) the result shows, recon-all: command not found It would be kind enough if you could please help me out. I am also sharing the screen shot of the terminal window I used for this programming, if it would e of any help. Thank you, Best regards, Koustav

Error in segmentation of the hippocampal subfields: /tmp/MCR_3634872073/.mcrCache8.4 error
by Pascale Patenaude 24 Mar '20

24 Mar '20

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to produce an automated segmentation of the hippocampal substructures and the nuclei of the amygdala (see hippocampal module https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAm…) When I try to run the segmentHA_T1.sh SUBJECT_ID [SUBJECTS_DIR] command with the dev version of freesurfer, I keep getting this error: [cid:ced2aa15-ebc9-4e8e-8555-471e7094cf73] I've tried setting the MCR_CACHE_ROOT env variable to somewhere under my user directory. Does anyone have any suggestions on how this can be fixed? Thank you in advance, Pascale

Re: [Freesurfer] Freeview Error
by fsbuild 24 Mar '20

24 Mar '20

External Email - Use Caution Hello Gian, I suspect the freeview binary is not going to be able to run on Debian linux.  We don’t build or test on Debian linux, but freeview/freesurfer should be fine on CentOS 6, CentOS7 and Ubuntu 18 for linux and also on Mac OS. Maybe someone could help you look at the steps listed here, https://surfer.nmr.mgh.harvard.edu/fswiki/VM_67  for running freeview in a virtual machine.  The instructions there are for setting up the virtual machine to run on Windows and the Mac - but those instructions should also basically work on (Debian) linux.  But you would need to have privileges to install VirtualBox, download some files and uncompress them, etc. - R.

Segmentation Issues
by Harriet Cornwell 24 Mar '20

24 Mar '20

External Email - Use Caution Hello, We are using FreeSurfer v5.3. and are sometimes finding that a brain can seem okay when it is first run through the recon-all process and is edited, but then when it is re-run the segmentation seems to deteriorate hugely. I have screenshotted an example below. Are you able to advise us on why this might be happening and what we could do about this? One of the options I had thought about was to re-run the recon-all from scratch but it doesn’t seem very time efficient to do this for multiple brains. Any suggestions would be gratefully received! Thank you.
