Hi,
I'm not sure whether the --seg option ever got looked into, but for
those searching the lists in the future, here is the quick hack I used
in perl to accomplish what I wanted:
mishkin
#! /usr/bin/perl
if($ARGV <1){
print "\nUsage: $0 \n";
print "Assumes SUBJECTS_DIR is set, and mri_a
Hi Martin,
it will dilate by one neighbor in the mess, regardless of distance. The
neighbors start out about 1mm apart, but there is some variation (which
is why it won't end up being exactly circular).
cheers,
Bruce

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

once every time you click "dilate label"

Hi Bruce,
if I dilate an arbitrarily shaped label in tksurfer, how much is it actually
dilated?
Thanks,

Hi Yigal,
yes, you can select the vertex, make a label out of it, then dilate it
however many times you want. This will be approximately spherical.
Alternatively you could write some code to use the ?h.sphere surface to
compute geodesic distances (great circles) to do it more exactly, but we

Hi,
In surface-based analysis, is it possible to create an ROI label that is
a circle of a certain radius around a given vertex?
Thanks,

you need to load it into tksurfer, which will sample it onto the surface.
Then save it again.

Dear All,
I've edited labels in tkmedit using the select voxel tool. I get the following
text file,where the vertex numbers are missing. Could anyone tell me what's
wrong about my procedure?
Thanks!!
