External Email - Use Caution        

Greetings,

 

I am trying to convert a surface label (e.g., lh.V1_exvivo.thresh.label) into a volume to use as an ROI mask.

 

I have played around with the mri_label2vol command, but I can’t seem to get it to work. Here is the command I am using:

mri_label2vol --label lh.V1_exvivo.thresh.label --temp T1.mgz --reg register.dat --fillthresh .3 --proj frac 0 1 .1 --subject sub1 --hemi lh --o V1Test.nii.gz

 

The issue I believe is that I don’t have seem to have a register.dat file. However, I’m not sure how to generate the relevant registration file since the surface label I’m using is already in subject space. The label that I need was created when I used recon-all to generate surfaces from my anatomical image. If it is relevant, my original anatomical image is a skull stripped T1 generated using FSL which I then converted to .mgz.


Does anyone have any insight? Thank you!

Vlad
