Hi,
I am trying to create cortical surface labels from several brain masks. All are .mgz files, separated by hemisphere, and aligned to fsaverage.
Here is the command I entered to create the labels:
mri_cor2label --i <filename>.mgz --l <labelname>.label --id 1
When I run this command, I successfully create the label, but I am unable to open the label in tksurfer. I've tried opening both from the GUI menu and from command line, and each time I get the following error:
--
******************** 0 nonzero vertices found ******************** label stat field identically zero - setting to 1 13245 unassigned vertices in label - building spatial LUT... assigning vertex numbers to label... MatrixMultiply: m2 is null!
--
And then tksurfer closes. I'm not sure why this is happening -- any help would be greatly appreciated!
Thanks, Sophie
