hippocampus misestimation
by Adam Mezher 05 Feb '14

05 Feb '14

Hi all, I was curious to know if anyone has been able to use edits to correct hippocampal under- or over-estimation. I've experienced a number of cases in which about half of the left hippocampus is labeled as ctx-lh-unknown or Left-Cerebral-White-Matter (for reference, I'm using FreeSurfer version 5.1 for these projects). If anyone has any suggestions to correct this error, it would be much appreciated. Thank you, Adam *Adam MezherStaff Research Associate IICenter for Imaging of Neurodegenerative DiseasesSan Francisco VA Medical Center4150 Clement St. (114M)San Francisco, CA 94121Tel: 415-221-4810 Ext. 4629 Fax: 415-668-2864*

from label to mask diffusion space

Hi Doug, I've been reading the list and I ended with 4 steps to move from a label to a mask in diffusion space (below). Is this correct? Is there any other more straightforward way? It should end with a binary mask in diffusion space (I am using the anatorig2diff.bbr.dat created in the Tracula process). tkregister2 --mov mri/rawavg.mgz --targ mri/aseg.mgz --regheader --reg mri/rawreg.dat --noedit Create volume (it does it in LPS ): mri_label2vol --label label/lh.th13labels-001.label --temp mri/rawavg.mgz --reg mri/rawreg.dat --fillthresh .5 --o mri/fromlabel_lh.th13labels-001.nii Move volume to anatorig (LIA) : mri_vol2vol --mov mri/fromlabel_lh.th13labels-001.nii --targ /mri/brainmask.mgz --regheader --o mri/anatorig_lh.th13labels-001.nii --no-save-reg Move to diffusion space (LAS): mri_vol2vol --mov dmri/dtifit_FA.nii.gz --targ /mri/anatorig_lh.th13labels-001.nii --inv --interp nearest --o mri/diff_fromlabel_lh.th13labels-001.nii --reg dmri/xfms/anatorig2diff.bbr.dat --no-save-reg thanks!

mris_divide_parcellation replication
by Christian Brodbeck 05 Feb '14

05 Feb '14

Dear Freesurfer developers, I am trying to replicate mris_divide_parcellation for mne-python (https://github.com/mne-tools/mne-python/pull/1085) I think I am doing the same as the MRISdivideAnnotationUnit function (https://github.com/neurodebian/freesurfer/blob/master/utils/annotation.c#L4…) but the result still looks different. Could someone point out how exactly the split is done, and if there are any steps in addition to the function? Are there any measures that are taken when the split would result in two disconnected regions belonging to the same label? And what surface is the split performed on (I would assume that would be “white”)? Thank you! Christian

Significant cluster only shows up in the terminal but not on the template brain
by Tudor Popescu 04 Feb '14

04 Feb '14

Dear Freesurfer experts, I ran a QDEC analysis for structural data and found, after Monte-Carlo correction(a)0.05, one significant cluster, annotated as "postcentral" (see screenshot attached). The stats associated with it are displayed in the terminal, however the statistical map on the template brain is blank. Also, when I press the "Find Cluster and Go To Max" button, I receive an error that no stats can be generated for that cluster. Not sure if it's relevant, but my dependent variables of interest in this analysis were thickness and local gyrification index (lGI). It seems I'm getting the above problem only when lGI is the DV, and whether or not there is a group factor among the categorical predictors. I do have, however, lGI analyses where the significant cluster shows up fine both on the template and in the terminal window. Can anyone help? Many thanks in advance! Best wishes, Tudor

mri_segstats - Manual Parcellation
by Gonzalo Iribarne 04 Feb '14

04 Feb '14

Hello Freesurfers, I am manually parcellating a cerebellum using Freeview and would like to compare #voxels across filled-in ROIs for reliability control. When using mri_segstats, which should be my segmentation volume? I have included my parcellation volume in the --mask option to target the voxels in my ROIs. Is this necessary or can I simply define my --seg volume as the manual (M_Parc.mgz) parcellation volume? Here is my command: mri_segstats --seg mri/testM_Parc.mgz --sum stats/testM_Parc.stats --pv mri/norm.mgz --excludeid 0 --mask testM_Parc.mgz --ctab /Volumes/share/Cerebellum/CerebellumStudyLUT.txt --subject 19 Thanks in advance! -Gonzalo Iribarne
