Analyze unaligned ncrna2

[eggzilla]

Hi, this branch supersedes the branch unaligned-ncrnas-analysis (https://github.com/galaxyproject/training-material/pull/1502). I forked again from master on advise from @bebatut during GCC.

@eggzilla this PR is now almost 4 years old, shall we close it or do you plan to work on it still?

@pavanvidem do you think you have time to finish this one?

[pavanvidem]

It seems to be finished and ready to review. Let me test it once.

Great, thanks for looking at it @pavanvidem!

I tried the tutorial. It worked until the Align sequences and extract representative sequences step. Then it fails because Select Sequences tool produces empty alignments. I have to find different parameters to make it work. There are also some open questions in the tutorials. It needs more understanding of the topic to fill those gaps. I don't think there are (m)any users for this tutorial now. If there is a possibility we can archive this and resume later if we plan for the next release of RNA workbench.

@pavanvidem thanks for testing it! Sure, we can just leave it open then until those last points have been addressed, just good to know there is still interest in finishing it :)
