If you have a template volume with the geometry you want, you can try:
--like templatevol

Hi all, I'm trying to resample an image into a talairach transformed volume from the 256^3 dimensions into 172 x 220 x 156. I've been using mri_convert in the following command line:
mri_convert -at transforms/talairach.xfm --devolvexfm 000718_vc4734 -cs 1 -oc -0.0950 -16.51 9.75 -ic 0 0 0 -oic 172 -ojc 220 -okc 156 -odt uchar nu nu_talairach_new3.img
It ran very nicely, but the anterior and posterior (frontal and occipital) regions are cut off, like they were cropped off. I suspect it is because data is being conformed to 256^3 in all directions and is just cropping to fit into my specified dimensions, but that is not what i would like to do. How would I be able scale it to fit into my specified dimension? I have tried -sc, but no matter how much smaller i seem to scale it, it's not enough to compensate for the crop.
thanks for any help! Tracy Wang
