Wendi,
Remove LITTLE_ENDIAN from your options line.  There's no such option.

Try displaying ref or vel upon first opening the file.  If your file names
don't match the template strings you've set in the DSET line of your
control file, then you will get the "Cannot contour grid" error.  Other
than that, your script looks okay.  Just make sure you can display all the
base data first before trying to manipulate it.

Jeff
