Hi,
I've done some statistics on thickness and volume of the default cortical regions (segIDs 1000 - 1035 and 2000 - 2035) for a number of subjects. How can I show for instance the p values (expressed as -log(p)) as an overlay on the pial surface of fsaverage?

Hi Ed,
sorry, I keep hoping someone else will respond as we did put something together to do this once upon a time, but apparently it's faded from all of our memories. You could do it in matlab by loading the parcellation and just setting every vertex with the parcellation value to the same scalar.

Hi Bruce,
I'm not familar with matlab but I can read the matlab scripts to understand what they are doing. I can then convert the code into C code. Which matlab script can I use to load the parcellation?
My suggestion would be to load the ?.thickness and replace the thickness values with the corresponding -log(p) values. However, I don't know which thickness in this file belongs to which segID?

read_annotation.m will load a .annot file. We'll try to digup the tksurfer bit that did this
