tabix

generic indexer for TAB-delimited genome position files

Tabix indexes files where some columns indicate sequence coordinates: name (usually a chromosome), start and stop. The input data file must be position sorted and compressed by bgzip (provided in this package), which has a gzip like interface. After indexing, tabix is able to quickly retrieve data lines by chromosomal coordinates. Fast data retrieval also works over network if an URI is given as a file name. This version of tabix is built from the HTSlib source.
