+**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.
