Hi Angela
in tksurfer you can show the overlay, and use the "custom fill" button to fill the area that is above threshold on the surface. Then save it as a label and use mri_label2vol to write it into a volume. If the output volume you give has the extension .nii.gz it will save it in nifti for you
cheers Bruce

Dear all, I found some interesting findings about gyrification and I would like to test any related problem in structural connectivity. My idea was to use the area where I found significant lower gyrification in my sample to perform probabilistic tracking with FSL. My question is: is there any way to label the area of significant difference (or I have to manually draw it) and to transform it in a nifti format?
