Yes, you can either provide the names with the argument coordFields of scanpyToCellbrowser yourself or let the new version do the job, it autodetects fields and uses all keys of the obsm object. (you may remember that this was a problem before in with older scanpy versions, due to the breaking changes in scanpy, but we've found a way around that, I think we talked about that in a previous discussion). The code for this is now in cellbrowser.py / writeAnndataCoords.
What is "_hm" ? Or "_1" and "_2" ? I've never seen these before.
Hm... are you on the current release...? I thought we had released this code...

do you have in newer versions more flexible ways of picking up the tSNEs and UMAPs on that AnnData? If that is the case, could you do a new release, as I need one that includes a defensive fix for #177 https://github.com/maximilianh/cellBrowser/issues/177 . Thanks!

There is no release yet that covers #177. I will try first with your dev version with what I'm trying and see if it doesn't require any further changes and let you know.
That will be extremely helpful, thanks!

Ok, this seems to be working on the latest version. Could you please do a release that includes #177 and then I can use that? Thanks @maximilianh!
OK, will try to release today or early next week.

This should be fixed now.
