Hi Everyone,

I remember a post in March when Allison referred someone to this page:

https://surfer.nmr.mgh.harvard.edu/fswiki/tksurfer_labeledit

and I think this will be really helpful for me if I can figure out how to make it work.  I have a scan with corpus callosum bleeding into the caudalanteriorcingulate.  When I try to change the label, I am able to select the region by clicking on it.

However, when I try to “Draw a complete outline path that encloses the desired "incursion"”, every time I click to draw the path, the image refreshes. 

Here are the instructions:

“Create outline path:

    *

      Possibly start with Edit > Unmark all vertices

    *

      Make a series of clicks along the desired outline path. tksurfer shows marked vertices.”

Is “create outline path”  the same as “Make Path” on the TkSurfer tools box?

What would make the decision between “Possibly start with Edit > Unmark all vertices” and not doing that?

I succeeded once in getting the path drawn, but have no luck replicating that.  Also, when I tried to relabel the part inside the path, I was able to turn it into label = “None” or turn 90% of the brain into caudalanteriorcingulate.

I’m missing something really simple here – help, please.

Also – can this be done also on the pial surface using this command?  I can see the boundaries better on this view than on the inflated

tksurfer $i lh pial -annotation aparc

Thanks for any help – let me know if you need more information
