Hi Sara, I'm not sure what you are trying to do. Are you doing a volume or surface-based analysis? If surface based, why do you need to convert it into the volume? doug

Hi,
I would like to create an overlay from a number of labels from the standard 2005 aparc in order to perform an fdr correction of a significance map using a mask to restrict the search space. I would like to do this with fsaverage.
As far as I can tell, there is no label or annotation to surf function??
What I have done so far is group my labels into one larger label using mri_mergelabels. Then I have converted this label to a nifti volume using mri_label2vol (I tried using this command to create an mgh file, and it did, but I was not able to subsequently open this as an overlay in tksurfer). What I then wanted to do was convert the volume to a surface using mri_vol2surf, BUT I don't have a registration file, as this has all been done with fsaverage.
I feel like there should be a simpler way to do this though! Any advice appreciated.
Thanks,
