Brodmann areas volumetric parcellation freesurfer 6.0
by Ahmed Radwan 08 Oct '21

08 Oct '21

External Email - Use Caution Dear FreeSurfer experts, I would like to generate .mgz Brodmann parcellation maps in FreeSurfer 6.0 (freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c) to be precise. Is this possible? I found this thread (https://secure-web.cisco.com/177FKNV88nkCNrwgn4jIC93-E_ZjHSBW0BXiH1uX3pOj28…) asking a similar question but aiming to propagate those parcellations into WM using FS 7.1. Thanks in advance, Ahmed Radwan

External Email - Use Caution Hi all, I have a between subjects factor (3 groups) and within subjects factor (3 stimuli type). I am interested in comparing cortical volume differences between groups and stimuli (i.e. group x stimulus interaction). What pipeline can I use to examine this? Many thanks, Abbie

SAMSEG output orientation not the same as input images
by daedalus39＠aol.com 08 Oct '21

08 Oct '21

External Email - Use Caution We have recently installed FS-7.1 and have tested a few “ADNI” images with SAMSEG. The process runs to completion, but the output (seg.mgz) appears upside-down and rotated about 90 about the X-axis. We are passing seg.mgz through BrainStorm to create NiFTI images. We do not believe that this is a BrainStorm issue inasmuch as the same images run through recon-all (fully separate proc) yield output images in the same orientation as the original images. I found a thread from 2012 with a similar output orientation issue, but the I did not see a response that resolved this. Any solution or insight would be greatly appreciated Sincerely,Randolph Andrews (PS. listserv item from 2012)Re: [Freesurfer] integrating FSL and FreesurferChris Filo Gorgolewski Tue, 09 Oct 2012 01:03:57 -0700https://http://secure-web.cisco.com/1bJm-kJVNOrTUaWjoqVk32d_m43kHXTpDrk8lcY-0m9IZL70ouR0Amj-rARrWUqpHqs37bd05gpqsZ5ysfX2IwhyEvB-jtySLbpgfVIwI9odls_4K82Kvhw3QUndLV0gJI7R_qOETwN5R8IsMiDFIovreM-3E6uNLDr9ua3ZEczUFu9zQt9L__yWHK3owmBE4NgW7-Jnn33sNGKV7QlzDb88gcre-4JwPKkrKdRylwImRU0aoDyCaRRFgoCRV_0jNFU_SZCrwzKcpPOyFWMzFRA/http%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg24896.html

non-brain tissue segmentation from T1-w images
by Banik, Rana 08 Oct '21

08 Oct '21

External Email - Use Caution Hello All, I am a beginner in freesurfer. Was looking for resources to perform volumetric segmentation(not surface mesh) for non-brain tissues like Muscle-skin, fat from T1-w MR images. Is that feature available in freesurfer? I have used FSL for WM, GM, CSF segmentation. Also looking to protect the inter-subject variability without registering the head volumes to MNI or another atlas. -Rana

Running -localGI without Matlab
by Soichi Hayashi 07 Oct '21

07 Oct '21

External Email - Use Caution Hello. I am trying to run recon-all with -localGI option. I am running freesurfer on HPC clusters where there is no Matlab license. When I add this option, freesurfer fails with this error message. mris_compute_lgi --i rh.pial ERROR: Matlab is required to run mris_compute_lgi! I am running freesurfer where it has access to MCR runtime to run compiled Matlab script. Is it possible to compile whatever the Matlab script that this module is using so that it can run without the full Matlab installation/license on our HPC systems? Thank you! Soichi

Re: [Freesurfer] Source freesurfer functions into R Studio Terminal
by fsbuild 06 Oct '21

06 Oct '21

External Email - Use Caution Hello Shrikanth, When you source the freesurfer setup script in your shell, e.g., bash, $ source $FREESURFER_HOME/SetUpFreeSurfer.sh - it sets your PATH, SUBJECTS_DIR and a few other variables.  It’s the addition to PATH of something like /usr/local/freesurfer/7.2.0/bin that enables freesurfer commands to be found, e.g.,  $ which mri_convert$ /usr/local/freesurfer/7.2.0/mri_convert So you could cut and paste the absolute path of a freesurfer command to run in the R environment via the system() command, i.e., use whatever is echoed by the “which” command above in the shell where you run freesurfer. You could also try to use a wrapper script to reproduce setting PATH and the freesurfer environment and run that script in the system() call.   Something like (change path to FREESURFER_HOME as need be), $ vi  fs_from_r.sh — start here —#!/usr/bin/env  bash  export FREESURFER_HOME=/usr/local/freesurfer/7.2.0 source $FREESURFER_HOME/SetUpFreeSurfer..sh  # add any freesurfer commands after this — end here — $ chmod 755 fs_from_r.sh Test run it in your bash sell first to see that it works, $ ./fs_from_r.sh Then see if you can run the fs_from_r.sh script via the R system() command.  You probably need to give the absolute path to the script though. - R.

Source freesurfer functions into R Studio Terminal
by Yadav, Shrikanth Muralidhar 06 Oct '21

06 Oct '21

Hello Freesurfer Developers, I had a freesurfer-Rstudio issue today which I solved by just working on a Linux shell script. However, I wanted to know if it is possible to send freesurfer related commands from R studio out of curiosity. My Problem: * I was trying to use freesurfer commands like mri_convert by sending them through the "system()<https://www.rdocumentation.org/packages/base/versions/3.6.2/topics/system>" function in R. * However, I got a "sh: mri_convert command not found" error. This indicates freesurfer is not sourced into the Linux terminal in the R Session. My Question: Is it possible to run freesurfer related commands from the rstudio terminal? What I did: 1. I looked up this problem online and found a similar example<https://stackoverflow.com/questions/26065564/why-cant-i-call-system-functio…> where the user needed the function bedtools. But updating the system path still threw the same error with . 2. In addition, I was able to send commands like "dcm2niix" from R using the system function mentioned above. I am certain this is a sourcing issue. Would appreciate any insight Thank you Shrikanth
