Merging virtual datasets

[Adrian Fraser]

Hi all,

I'm running into filenumber quotas on Pleiades, and it would be great if I could merge datasets and have a single .h5 file rather than a virtual file and all the, e.g., slices_s1/slices_s1_p*.h5 files. It looks like this should be doable with post.merge_virtual_analysis(), but I'm getting errors along the lines of:

KeyError: "Unable to synchronously open attribute (can't locate attribute: 'set_number')"

and

KeyError: "Unable to synchronously open attribute (can't locate attribute: 'file_number')"

whenever I try. Is there some other method I should be using?

Thanks,

Adrian

Here's the complete error message in case anyone has a chance to take a look.

Hi Adrian,

You might want to look at this pull request. If you are especially keen you could try to implement the proposed changes so that we could merge a fix in (at this stage probably more efficient to have a new PR because this one would require significant rebasing).

Daniel
