| I am working in PET, but we have T1 weighted (SPGR) MRI's (GE) for the
| subjects on which I'd like to display activation. I note that the
| gray-white contrast is rather poor, and quite variable between subject
| volumes. In one volume in particular, the volume is quite dimly displayed,
| and difficult to see.
|
| The only visual controls I can find are on the graphic output box, and
| they are limited to brightening or darkening the image, overall. Are there
| any other tools for better adjusting the gray-white contrast?
You can display the results via the <Display> function. This allows you
to specify an intensity "window".
Alternatively, you can window the display from the results section by:
spm_orthviews('window',1,spm_input('Range','+1','e','',2));
Best regards,
