Dear Doug,
Thank you for your recent advise with using freesurfer to extract mean values from non structural image data. Is there a way to generate an image (e.g. heat map) displaying those values in free view?
Best wishes,
Sal
Do you mean table data or data that you have on a map? On 05/31/2013 03:20 PM, Salil Soman wrote:

I have been able to generate the table. I was asking about an actual image (that could be visualized in freeview or something else).
Thank you.

you can just specify an overlay on the freeview command line

Dear Doug,
Thank you for your response. I am not sure I understand what I would be overlaying.
I would like to display the T1 volume for the subject, but for each voxel color value, I would like that to reflect the mean intensity value that I calculated using mri_segstats. I do not see a way to do this in freeview. Any pointers to further details would be greatly appreciated.
Best wishes,
Sal

if you are working with the aseg, then you could
aseg = MRIread('aseg.mgz'); overlay = aseg; overlay.vol = zeros(size(overlay.vol)); ind = find(aseg.vol == 17); % Find left hippocampal voxels overlay.vol(ind) = value from you table corresponding to left hippo
you would then replicate with each ROI. The "17" comes from $FREESURFER_HOME/FreeSurferColorLUT.txt
