@nsheff - does this look good? I think this is the only thing remaining for us to get the RefGenie iGenomes on parity with AWS-iGenomes now.

[nsheff]

Ok great -- I will finalize this very soon

Hi @nsheff - anything we can do to move this PR along? 🙏🏻

[nsheff]

The input file is actually expected to be in gzipped bed format, right?

[nsheff]

I updated the key to bedgz to reflect that you're actually wanting to store a gzipped bed file

[ewels]

Nope, we've been using raw bed files - not compressed - until now (see path here for example).

But you're right, we should probably be using gzipped files. Means updating all of the code using these references but shouldn't be too difficult as long as we remember.

[nsheff]

Ok -- I ask because the recipe was naming the file .bed.gz, so this wouldn't have worked with raw .bed files... well, they would have been bed files named blah.bed.gz...

[ewels]

Oh I see 😅 Ok I'm sure it's fine, as long as @mirpedrol is on top of things 👍🏻
