Hi Doug et al.,
when using mri_label2label with the --regmethod volume, there are no vertices output in the .label file. When loading the .label file into tksurfer, it crashes tksurfer without any error message.
It is possible to obtain vertices and to visualize them for the results of mri_label2label when using the volume regmethod?
Best, Darren

Currently not. What is it that you are trying to do? Do you just want to apply a transform to the label coords but keep the vertex numbers?

Hi Doug,
it would be useful to identify the Talairach coordinates for the center of mass, among other things, such as the spatial spread of a label in Talairach coordinates. I suppose there are other ways of doing that.
I am wondering, is it sensible to compare the results of the 'surface' and 'volume' regmethods?
Thanks, Darren

I guess you could compute the cog in native coords, then convert those coords to tal (would probably be the same thing as starting in tal). Having said that, I don't have anything which will compute the cog along the surface. The right way to do it is to map the label to the sphere, compute the cog there (where it is easier to compute distances), then find the closest vertex to the cog, get the native space coords for that, then convert those coords to tal. I'll add this to my to-do list (but feel free to ask me about it if I don't get back to you:).
