Thank you very much. |> -------- |> Thomas Skill |> tskill@monarch.papillion.ne.us |> AFGWC Offutt AFB, NE 68113 Thomas, You could re-scale all your images to use the same color table, put them in a 3d array and use MOVIE, ie. moviedata=bytarr(xsize,ysize,nframes). Or in WAVE there is also the WgAnimateTool procedure. -- Todd Ratcliff UCLA Dept. of Earth & Space Sciences Room 2707 Geology Building UCLA Box 951567 Los Angeles, CA 90095-1567 todd@artemis.ess.ucla.edu (310)825-3118 http://artemis.ess.ucla.edu/~todd/home.html
