I am using FLIRT to register ANALYZE images, but I am left confused by the
output matrices. The output images look good, so I know the registration is
successful, but I can't figure out what the shifts in the registration matrices refer
to (units). Reading past mailing lists, I gather the shifts are reported in mm. True
units are not important for this project, so I have the pixel size set as 1mm^3 in
the ANALYZE headers. I hoped this would produce output matrices with
translations in # of pixels, but it doesn't seem to correspond properly. Is there a
way to get these translations simply in # of pixels?
Thanks in advance to anyone with suggestions!
