I have a customized version of spm_orthviews, which can be downloaded
as part of my recommended local modifications
http://www.sph.umich.edu/~nichols/spm99_umlocal.tgz
http://www.sph.umich.edu/~nichols/spm2_umlocal.tgz
I would pick through them to see what each one does; here I'm
just referring to the spm_orthviews and related mods.
You can fix the max value as follows. In SPM99, you have to issue
the command at the Matlab prompt:
spm_orthviews('addcolorbar')
In SPM2, you can do this, or add a colorbar to a CheckReg view by
right-clicking inside the image to get the context menu, and then
select Image -> Add color bar.
Once the color bar appears the maximum and minimum intensities are
fixed, based on a global min and max. More important, you can right
click on the *colorbar* to get a context menu to control the min and max
displayed intensities. For example, you can right click on the intensity
that you want to be the new maximum and then select 'Set Max'; likewise
you can right click and 'Set Min'. You can also 'Set Max - all images'
which will force all images in the Check Reg view to have the same max.
If you prefer, you can use the 'Manual' option to manually enter the
min/max range.
Hope this helps!
