Hi Devavrat
freeview definitely does not modify the values in any volumes you load
for display.

External Email - Use Caution
Hi freesurfer developers!,
I am using Freesurfer 6.0 and the latest (freeview -beta) to display overlays
on my flat surfaces.
I am a novice user of freesurfer and I am a bit confused with how the overlays
are displayed /
thresholds calculated.
My overlay of rsquare values ranges from 0.2 to 1.0 (i.e all are positive
values.). When the overlay is
loaded, the threshold histogram depicts values that are negative and positive
(centered around zero).
1) Does freeview recaluate/modify the values before they are displayed?
2) Is it possible to display the values of the overlay as they are?
Thank you. Stay healthy and safe!
Best,
Devavrat
