Thanks to everyone for their assistance in my adventure of custom local datatypes. In response to this, I've added a new wiki page with a basic MWE/tutorial on adding datatypes. A complete example is at the end, because most people like copy+paste code to get them started.
https://wiki.galaxyproject.org/Admin/Datatypes/AddingCompleteDatatypes Please feel free to add to it/fix things I completely misunderstood.
I'm not sure what 80% of the functions that get called in datatypes do, nor where they're called from, so I can't offer much more detail in this wiki page than I already have. (E.g., when is split called? If I write a split method, how can I test it? What other methods should I implement?)
Cheers, Eric
Hi Eric,
Good work :)
Split and merge are used when a tool has a <parallelism .../> tag and this is enabled in your universe_wsgi.ini file. As an example, see the BLAST wrappers, e.g.
https://github.com/peterjc/galaxy_blast/blob/master/tools/ncbi_blast_plus/nc...
This will split on the query FASTA file, and merge on the output file (which could be text, html, tabular, blastxml) using the output datatype's merge method.
I had to work out a lot of this from reading the code and queries on the mailing list.
