[DAS] Survey on DAS projects

Hi Andy,

thanks for the info. Having a bed DAS adaptor is part of the problem,
the other is not having to worry about having to deal with the DAS
server directly. easyDAS manages to do this but unfortunately it is
not obvious for people who do not know DAS how to operate it. Also if
the file is very big and the connection slow it can take up to an hour
to create a DAS source.

Wouldn't it be nice to create a DAS source just with one click or two?

Please see below a snippet of a few SNPs in my chromosome 16 just as
you would get them from 23andMe (NCBI36 assembly; columns mean

It also supports Hydras, which are modules that are designed to automatically create DAS sources from a single config without restarting the server. This is how EasyDAS works with ProServer: there is one SourceAdaptor, and a Hydra to scan a relational database for new data.
> I don't know what 23andme's data looks like, but the addition of a Hydra to scan directories for new files and automatically make them available as DAS sources would seem to be a trivial piece of work. I daresay a VCF adaptor would also be fairly easy, especially if there is a Perl API of some sort (BioPerl?).
