+ 23 July 2010 - BigBed/BigWig Paper Published +
+Last summer, we announced the release of new data formats for very large data sets: BigBed + and BigWig. Read more about these data formats + here. As a follow up, we are pleased to announce that we have published a + paper on these new file formats. + +
+ Kent WJ, Zweig AS, Barber G, Hinrichs AS, Karolchik D. + BigWig and BigBed: enabling browsing of large distributed data sets. + Bioinformatics. 2010 July 17. Published online in advance of print. ++ +
From the abstract:
+ BigWig and BigBed files are compressed binary indexed files containing data at several
+ resolutions that allow the high-performance display of next-generation sequencing experiment
+ results in the UCSC Genome Browser. The visualization is implemented using a multi-layered
+ software approach that takes advantage of specific capabilities of web-based protocols and
+ Linux and UNIX operating systems files, R trees, and various indexing and compression tricks.
+ As a result, only the data needed to support the current browser view is transmitted rather
+ than the entire file, enabling fast remote access to large distributed data sets.
The supplemental materials (available online) contain the technical details about the + implementation. +
