Well, sorta. :-)
The * indicates a data range, (eg, 0:sizeOfX-1). Your
data is, occasionally, smaller than that. And the array
on the left hand size will have to equal the size of the
array on the right hand side, or IDL will complain like
this.
There is a trick, though. If you specified only the
*first* value of the data range, IDL will try to fit
your array into the larger "space" on the left hand side.
Try this:
data[0,0,I] = framearray
I think there is a good chance you will get away with that. :-)
Cheers,
David
