variable: $invertmoveflag -- invert MOVEABLE scan
default: 1 (TRUE)

When invertmoveflag is 1 (invertmov is selected),
the contrast of the MOVEABLE scan (e.g., a
T2-weighted functional EPI scan) is inverted to
aid visual comparison with the TARGET scan (usu.
a T1-weighted FLASH).  Note that this also
inverts the operation of the "fmov:" field --
that is, higher fmov values make the MOVEABLE
scan *darker*.  Unclick to align two T1 scans.
