[Freesurfer] export hippocampal subfields using mri_binarize

2012-03-15 Thread Catarina Duarte
Hi all, I am trying to export the hippocampal subfields generated in Freesurfer 5.1. To do that I use mri_binarize with a minimum voxel threshold of 150 and a maximum of 255. However, some of these regions appear overlapped. Why does this happen if a minimum threshold of 150 correponds to a

[Freesurfer] Crippled fiber tracts in healthy subjects (TRACULA)

2012-03-15 Thread Ansgar Furst
Hi, We are using the ADNI Acc 3D FSPGR for structurals and 30 directional (5 B0s) repeat sequence for DTI which so far rendered really nice results. However, recently I encountered data from several healthy young subjects where the TRACULA fiber tract estimations would suggest severely crippled tra

Hi Ansgar, Can you send us an example screenshot of the one of the fiber tracts that look crippled? If you can send us an overlay of path.pd.nii.gz of that specific tract on the FA map, it will give us an idea of what is going on. Best, Priti > Hi, > We are using the ADNI Acc 3D FSPGR for struct

Hi Doug, As a post-mortem to this thread, in the process of going to "tweak" the wm.mgz as you suggested, I noticed that there were actually some substantial errors in the surfaces in the calcarine, presumably due to topology correction gone astray. So, whether or not that precipitated the probl
