Dear experts,
I'm trying to create labels for subcortical regions. I want to use these labels to extract time series from resting state fMRI data (I want all of the subcortical time series and I want them to be in mni305 space). I'm not sure if I'm doing the right thing. Here's an example of what I used: mri_cor2label --c $FREESURFER_HOME/subjects/fsaverage/mri.2mm/aseg.mgz --id 255 --l ~/Desktop/CC_Anterior.label
After running this command, attached is the label file I get. The first column is all "-1"s.
any ideas how I can go about doing such thing?
Best, Ladan
