That's right. The bounding box is maintained and the original data are (weighted-average) interpolated to the Reduce'd resolution grid.
For subsampling, you can use Slab/Slice/Stack to do this doing some book-keeping in the process. Here's an example of this idea with a macro. (See attached file: SubSample.net) I haven't used it in awhile and I wrote it over 4 years ago, so I can't vouch for it working perfectly with OpenDX. But it should help you get started. -------------------------- Lloyd A. Treinish Deep Computing Institute IBM Thomas J. Watson Research Center P. O.

However, I want to only subsample the field, and don't need the filtering. What should I do? Thanks. yuzhong
