[Homer-users] Error in using create_HeadVox.m

[jdubb at nmr.mgh.harvard.edu]

Hi Maheen,
I'm not clear about this issue.

I couldn't find a script called create_HeadVox.m
under Homer2. Where is this script supposed to be in the
Homer2 folder structure?

Are you trying to convert Freesurfer files to AtlasViewer?
If so I'll need more info on what Freesurfer files you have
in your subject folder.
