**What it does:** 

The input data file is sorted and compressed by bgzip which has a gzip(1) like interface. Tabix requires the file to be compressed using this tool first.

**Citation:**

Tabix was written by Heng Li. The BGZF library was originally implemented by Bob Handsaker and modified by Heng Li for remote file access and in-memory caching.
