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
