there is some code around to display each parcel with a different value,
but I'm not sure exactly what it is. YOu could certainly do it in matlab
if you wanted to (use read_annotation.m to read in the .annot file)

Hi Bruce,
Some background:
I have already extracted ROI timeseries using the following method:
- use mri_vol2vol to transform the functional images to structural space
(yes these were very large images; I did it one at a time)
- use
Hi Ben
can you explain a bit more explicitly what you are trying to do? The
annotations are exactly what you suggest (a parcellation ID for every
vertex)
cheers

Could you tell me how I can map a particular ROI (for instance the
Destrieux cortical surface ROIs) to a set of vertices that make up the ROI?
Is there a lookup table I can use?

Hi Ben,
My last email was referring to how to load custom color map for volume
viewing. If you want to load custom color for surface, you need to
create and load an RGB map file. The file can be a text file contains N
lines of RGB color like this:
R1, G1, B1
R2, G2, B2
...
or a volume

I've been trying to do this as well, but I can't see the right place to
specify in freesurfer to specify an alternative lookup table.
For instance, if I am coloring a pial surface, then the first possibility
is to set a Color (where I can "load RGB
It looks like a customized look up table will work for your case. You
can simply select "Lookup table" as the colormap and load your own
lookup table. To create your own look up table, you can refer to the
content of FreeSurferColorLUT.txt file in your freesurfer installation
directory.
Hi all,
I’m wondering whether there’s a way to create a custom color map in Freeview
that would operate as a alternative to the preset Greyscale, Heatmap, NIH, PET,
Jet and GE Color options.
Ideally, I could assign each number value a given color, e.g. every “0” value
in an .nii file is
