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
