Bruce,
Thanks for the quick response to my question. I've gone searching instructions
on how to run the mri_morphology command but I can't find anything in the wiki
or the mailing list archives. All I have been able to locate is the following
blub which I get by then I run the command with no flags.
usage: mri_morphology [options] <volume> <operation> <# iter> <out volume>
-u where which can be [dilate,erode]
Is there some place I can go for advice on how to run this? Once again I would
be interested in feeding is a set of XYZ coordinates and then creating a sphere
around them which I can then use as if it is a structural label.
Thanks again for your help,
Avram

Hi Avram,
mri_morphology implement general morphological operations on volumes,
including dilation. You'll need to convert the .label to a .mgz if that's
what you're using, then back to a label.
cheers,
Bruce

All,
I'm attempting to create some spherical ROIs around peak activated voxels

the volume. Is there anything similar to the label dilate function for use
in
the volume?
Thanks for any help you can offer,
