Inquiry about infant freesurfer pipeline - wm segmentation options
by Shinwon Park 02 Aug '22

02 Aug '22

External Email - Use Caution Dear Experts, We ran the freesurfer infant pipeline on our dataset consisting of 1 and 2 year olds, and noticed that the white matter segmentation does not perform well. Specifically, it does not extend all the way up to the lateral regions of the brain. Is there a way to modify some options to increase white matter segmentation coverage? For instance, in the adult freesurfer pipeline using the *mri_segment *command we can adjust the white matter low and high limits using the -wm_low and -wm_high flags, respectively. Looking through the commands of the freesurfer infant pipeline, the " *mri_label_fusion*" function which is called upon in the *run_label_fusion.sh* along with several other commands such as " *mri_correct_segmentations*" seems to play a key role in the segmentation process. However, we could not find any usage documentation for these commands. We would greatly appreciate If you could share the usage descriptions for the commands used in the freesurfer infant pipeline! Best, Shinwon Park

TRACULA in FreeSurfer version 7.3
by kingwai.chu＠gmail.com 01 Aug '22

01 Aug '22

External Email - Use Caution Hi Anastasia, � Just downloaded FreeSurfer version 7.3 and trying out TRACULA. Ran recon-all, segmentThalamicNuclei.sh, and trac-all in v7.3 However trac-all -prep is looking for ThalamicNuclei.v12.T1.FSvoxelSpace.mgz from segmentThalamicNuclei.sh which doesn’t exist. Because in v7.3, segmentThalamicNuclei.sh output a new version v13 (ThalamicNuclei.v13.T1.FSvoxelSpace.mgz). I worked around this problem by linking ThalamicNuclei.v12.T1.FSvoxelSpace.mgz to ThalamicNuclei.v13.T1.FSvoxelSpace.mgz ln -s ThalamicNuclei.v13.T1.FSvoxelSpace.mgz ThalamicNuclei.v12.T1.FSvoxelSpace.mgz � trac-all finished w/o problem. � trac-all -version trac-all 7.3.0 � I seems trac-all in v7.3 forgets to update the fact that segmentThalamicNuclei.sh output v13 of the file. Or it is looking for v12 for a reason? � Is my fix correct? � Thanks, � King-Wai

ROI analysis, S1, face area
by Eszter Boros 31 Jul '22

31 Jul '22

External Email - Use Caution Dear FreeSurfer Team, I would like to do a ROI analysis focusing on the primary somatosensory cortex (S1) using Freesurfer and see the potential alterations after a (behavioral) treatment . I am wondering how I can do that? First, I picked and looked at the postcentral gyrus and sulcus, but I am specifically interested in the face area. Is there a way to make my analysis more accurate? I am using Freesufer 7.1.1 Thank you for your answer! I greatly appreciate it. All the best, Eszter Boros
