It's a mass spec tracing database. Animals are infused with radio labeled compounds and mass spec is used to see what the animal's biochemistry turns those compounds into. (My undergrad was biochem, so I've been resurrecting my biochem knowledge, as needed for this project. I've been mostly doing RNA and DNA sequence analysis since undergrad, and most of that was prokaryotic. > One quibble with the Download tab, there is no indication of the size of the > datasets.

Not knowing the download size is exactly a complaint I had. That download actually uses my advanced search interface (in browse mode). There is the same issue with the download buttons on the advanced search. With the streaming, we're not dealing with temp files, which is nice, at least for the advanced search, but we can't know the download size that way. So I had wanted a progress bar to at least show progress (current record per total). I could even estimate the size (an option I explored for a few days). Eventually, I proposed a celery solution for that and I was overruled. As for the download in the nav bar, we have an issue to change that to a listing of actual files broken down by study (3 files per study). There's not much actual utility from a user perspective for downloading everything anyway. We've just been focussed on other things. In fact, we have a request from a user for that specific feature, done in a way that's compatible with curl/scp. We just have to figure out how to not have to CAS authenticate each command, something I don't have experience with.
