One more question regarding NaN voxels... I have the averaged activation
area of a control group... I wanted to use it as a region of interest for
tractography. when I tried to overlay them with the canonical t1 image of
spm, I could not because these images did not have the same dimensions... so
I tried to reslice them, but what I got was a cube whose voxels had a value of
zero, surrounded by a border of NaN voxels. all the activation areas
disappeared. Could you please tell me why? Is there any issue in reslicing
imagines which contain NaN voxels? I am using SPM5, by the way.
