Hi Lena, Have you tried loading your labels as a segmentation volume? As long as each of your labels has a different voxel value, you can load that label volume as a segmentation, and then make a corresponding color look up table making each label whatever color you want (as long as you can fi

[Freesurfer] multimodel wm hypointensity labeling?

2009-09-10 Thread Victoria Williams
Hello, Are there any freesurfer tools that allow labeling of wm hypointensities using imput from both T1 and T2 or lowb images? Also, I was wondering if there was further documentation for the use of the mri_relabel_hypointensities command? I got the impression this script dealt somehow with c

Hi, I have successfully run 126 subjects through bbregister and mri_vol2vol in order to translate the wmparc volume into TBSS space. However, there are 2 subjects that exited prematurely from bbregister. I think it may have to do with my naming system? 126 of the subjects have the subjid CVRA
