Re: [Freesurfer] Circle around vertex

Hi Martin --

There is an app in the development tree, 'mris_pmake' that can be used to generate fixed-radius regions about arbitrary vertices. It's scriptable, so you can feed it a list of vertex indices to build circular ROIs about.

It should be available in the 5.0 release of FreeSurfer, but if you'd like to use it already, send me an email and I can send you a beta version.

Cheers -=R

:) thanks. In volume images dilation is usually by 1 voxel, but as far as I understand, label is a surface represented by a mesh where a distance between vertices does not need to be the same. So if I want to dilate the label by 10 mm do I click "dilate label" 10x.

Thanks,

Martin
