Hi Jeff,
you should be able to use the "custom fill" tool to get what you want. The easiest thing is to use "up to and including threshold" (or something like that). After clicking in an active spot it will fill all the connected vertices that are above threshold and create a label, which you can then save.
cheers, Bruce

Hello all,
I am trying to hand draw ROIs from a functional overlay. The wiki mentions a Cut Area tool in tksurfer, which sounds ideal for getting rid of the area outside my ROI, but it's nowhere to be found in the tksurfer GUI for our installation, Centos 4 x86 64 bit. Has this tool been renamed or subsumed under some other tool? If there is an easier way for me to draw ROIs?
Thanks,
