We're happy to announce that we recently released version two of our
Database Definition Document
. This document includes all of
the currently supported track configuration options (trackDb) for
track and assembly hubs in the UCSC Genome Browser.
This latest version includes settings for our latest "big" track
types: bigMaf, bigChain, bigPsl, and bigGenePred. As well as the
"CRAM" track type. This newest version also marks the movement of
some trackDb settings (html, priority, colorByStrand, autoScale,
spectrum) from the "full" to the "base" support level to indicate
that they are supported by other genome browsers. At this time, it
is primarily Ensembl that supports the use of these new "base"
settings in track hubs on their site.
Additionally, we have posted a new
that discusses the versioning of these trackDb
settings and how you can use hubCheck to see if your hubs are
compatible with other genome browsers.
