Donna, Thanks for the quick response! I just uploaded "input_tal.L.full.sMRI.params" and "input_tal.L.full.sMRI.mnc" The original dataset was a local analyze format version of colin, which was then converted to minc using our own idl routines, and subsequently converted to the standard taliarach space used by Insect/Classify (from MNI). -Tim --------------------------------------- Timothy R.
