[Freesurfer] Probabilistic V1 labels to volume

2011-12-09 Thread Ian Charest
Hi There was a post recently on the mailing list about exporting Probabilistic V1 labels to a volume. I have applied the probabilistic mapping of an individual subject and now have the "lh.v1.prob.label" I would like to convert this label as a volume, and the function mri_label2vol is a litt

Hi Jen, the T1.mgz is in register with the surfaces by construction, so you shouldn't need any registration. cheers Bruce On Mon, 14 Feb 2011, Douglas N Greve wrote: > When you say the original T1, do you mean the data directly from the > dicom files? FS analysis is generally done in our "confo

When you say the original T1, do you mean the data directly from the dicom files? FS analysis is generally done in our "conformed" space (1mm isotropic, 256^3). One of those volumes is called "T1" and one is called "orig" -- this understandably confuses a lot of newbies (and oldbies). doug Je

Hi there, I'm not really familar with freesurfer and am missing the step on what to register to create the register.dat file required to use mri_label2vol to convert the probabilistic V1 label file outputs from a single subject to a volume. I thought the labels are already on the surface/vo
