The first parameter to immovie() must be an array of movie data. When you use the constant 330 there, you are implicitly asking for a single frame movie that is 1 pixel by 1 pixel of a color whose map index value is 330 (which would require that the map you pass in have at least 330 rows.)

Well, did you define map? If not, try just deleting it from the arg list and seeing if that runs. map is a colormap, for example

map=gray(256);

I bet you don't need it or want it.

[Walter Roberson]

The map _is_ needed if the original data is indexed images.
