C. briggsae operons

[MagdalenaZZ]

Multiple issues with the C. briggsae operons.
In the DB there are >1000 operons. Only 49 are dumped to the GFF. None are displayed in the JBrowse track.

With regard to JBrowse: all of the operons that are in the GFF are displayed in JBrowse 1 but that track hasn't been ported to JBrowse 2 yet (some "species specific" tracks haven't been done. I'm working on it this week.

Actually what I wrote above is not correct: there are no operons in the C. briggsae JBrowse of any version (I was looking at the wrong thing). Anyway, here's why: in the elegans GFF, there are three types of operons:

operon:operon
operon:deprecated_operon
operon:dicistronic_mRNA

but in the briggsae GFF, there is only operon:dicistronic_mRNA. I believe at some point, the operons in the briggsae GFF might have been something else (perhaps operon:operon) and I didn't catch the change. Anyway, I can update the processing and config to catch the operon:dicistronic_mRNA features. Of course, I can't speak to where the other operons in briggsae are.

Since Magdalena said there are >1000 operons in the database for briggsae, and this paper says they identified 1100 operons (https://wormbase.org/resources/paper/WBPaper00041271) I'm guessing those the operons that are missing in the GFF. I'm going to assign to Mark as a best guess of who could likely fix this. (actually, I'm not going to assign to @markquintontulloch because I don't appear to have that authority)

Will take a look @scottcain

I don't know what I was on yesterday, but dicistronic mRNAs are in both JBrowse 1 and 2 on both staging (WS288) and production (WS287), eg: https://wormbase.org/tools/genome/jbrowse2/?session=share-pXhyUFLl8h&password=IuYtq Perhaps it was because "Operon" wasn't in the name of the track :-)

Anyway, that at least is good news, since I don't have to track down a bug that was causing them to be overlooked.
