@omicsorama Hello. I see you also have a specs change proposed to add this value. I'm happy to add this update this but I'm going to wait for a bit in case there's any feedback on that pr.

Are you a representative of Singular? Are they producing data with this value at the moment?

@lbergelson Yes i made the parallel PR to keep docs and tool in step. Makes sense to wait a bit for feedback. Thanks.

Yes I am on the Bioinformatics team at Singular and we are holding off on producing data with this value until our customers can use a published htsjdk version that supports it

Happy to address any other questions!

@omicsorama Thanks for the info. It seems like it should be uncontroversial then if the name is coming straight from the source.

This seems to have been merged in specs so I'm going to merge it. Thank you @omicsorama
