External Email - Use Caution
Dear Ruopeng,
thanks for looking into this, and sorry for ma delayed reply. I have just read your answer.
I can certainly do what you suggest, but the color bar is a bit confusing, see attachment. Somehow it suggests that the threshold is 0.767, when indeed it is 1.23 (these numbers are chosen exclusively to describe the software problem and the maps represented have no sense).
When using the color bar in tksurfer the numbers shown intuitively revealed the threshold used in the map. What would you advice to do?
Thanks
Fabio

After you load the overlay onto the surface, you can click on “Configure Overlay” button on the left pane to adjust color scale and thresholds for the overlay.

even though on the official webpage it is advised to use freeview to display statistical maps because tksurfer is considered obsolete/not maintained in freesurfer 7, I am unable to reproduce the same figures, even when using tksurferfv.
one feature that is missing but can be reproduced using mri_fdr is FDR thresholding. however, it is not clear to me how to produce a decent color scale given a threshold computed by mri_fdr or any other means, which indicates the threshold.
could someone please suggest how to edit the color scale in freeview? or whether there is an alternative software to display the overlays/statistical maps produced by freesurfer?
thank you very much in advance!

Dear Greve,
thanks for your reply. These are my steps (I corrected the second):
- I open the inflated surface:
tksurferfv fsaverage lh inflated
(this successfully displays the inflated left hemisphere of the average subject)
- I now load the overlay from the freeview window (sig.mgh from a mri_glmfit)
(this successfully overlays the -log(p) statistical map)
- I would like to threshold the map using FDR<.05. This was possible in tksurfer:
https://secure-web.cisco.com/14RYweM71AH5pQm4yA5snEHYyrEVoKp3gpJ8mUW3BNypi7N...
however no such option appears in tksurferfv / freeview
Any hint at this point?
Thanks a lot
Fabio

your tksurferfv command line is wrong

External Email - Use CautionDear Freesurfers
I recently moved to FS7.1 and I was trying to reproduce my workflow I had with FS5.3.
To visualize statistical maps, I had always used tksurfer. It seems, however, it is no longer maintained.
When I launch it it fails to find out the tix, tcl, etc libraries. Following this thread: https://secure-web.cisco.com/1v7sQGKZgCQ9d6BT0fUpIf9QvmP5selhkoGYWs1-X9TSsF6...
I tried to use tksurferfv. However, when trying to overlay the sig.mgh output of mriglmfit, on an inflated fsaverage surface, the program shuts down, with this error:
freeview -f /usr/local/freesurfer/subjects/fsaverage/surf/lh.inflated:curvature=/usr/local/freesurfer/subjects/fsaverage/surf/lh.curv -viewport 3d terminate called after throwing an instance of 'int' Abort (core dumped)
What would you suggest to visualize statistical maps in FS7? Is my problem expected?
Thank you in advance for your attention
