Lauren,

You can use ENVI_GET_ROI_DIMS_PTR to get the dims pointer that should
replace the -1 in your dims array.

And as for the class_ptr keyword, this is the list of class numbers
you're going to get stats for, so if you only have one ROI, just set
it to 0 (ie, do the first class). If you have multiple ROIs, and you
want to get stats for all of them, you just need the number of classes
- so use something like class_ptr = indgen(num_classes).
