[MINC-users] minccalc

[Andrew Janke]

Looks right to me,

Sure you aren't getting bitten by a datatype and range issue?  What
type is your input image? byte?  by default minccalc will use the
datatype of the first input image for the output.

Perhaps add a -double in there and see if you then get what you are
expecting.  Beyond this you are going to have to provide a bit more
info than "not what they should be"... :)
