Re: [Freesurfer] "Splotchy" labels after transformation from fsaverage to native

Hi, just wanted to bump this up since it looks like Doug is back.

Hi,

I'm using mri_label2label to reverse normalize labels from fsaverage space to the native surface.

I'm ending up with some splotchy-looking labels, for lack of a better word. See what I mean here: http://web.mit.edu/mwaskom/www/splotchy.png

I'm doing this normalization in a script with the following relevant line, which seems to be what happens inthe BAlabes step of recon-all

mri_label2label --srclabel ../fsaverage/label/${hemi}.${roi}.label \ --srcsubject fsaverage --trgsubject ${subj} \ --trglabel label/$hemi.${roi}.label \ --regmethod surface --hemi $hemi

Any idea how I can avoid this splotchiness or, failing that, do a closing on the label to clean up some of the noise?

Cheers, Michael
