I am trying to register a lowb volume to an average volume.
In this particular case, I'm trying to use tkregister2:
% tkregister2 --targ avg_000.bfloat --mov indivsubj_000.bfloat --reg \ register.dat
I am having a problem with the brightness of the TARG volume. It seems to be set near ~1, and using the fmov option only adjusts the brightness on the MOV volume. It is kind of hard to align them, when the target volume looks like a binary mask (appears all white). Have you seen this before?
Changing the contrast doesn't seem to help.
Thanks, George P.
