Hi @nperez
This is the use case about using the existing mask file in the analysis. We talked about it in issue #4 (closed).
When creating this use case, I found another bug about metadata (related to !90 (merged) and !92 (merged)) and I solved it in this branch. The bug is that the previous bugfixes for metadata didn't consider the case that retrieves two variables for one file. We can include this fix in the next release.
Cheers,
An-Chi
