< Kaviar >	(~Known VARiants) is a very simple tool for answering a very specific question: What variants have been reported already for a given specific genomic location?
This is the 2011 version of Kaviar. Visit db.systemsbiology.org/kaviar for latest version.
1. Specify the coordinate system	Human reference version (freeze) is hg18 (NCBI Build 36.1) hg19 (GRCh37) Coordinates are zero-based one-based
2. Specify your queries Enter genomic positions. Not genomic ranges, but rather specific positions you're interested in. You can use a variety of supported formats.	Chromosome: (e.g. "chr1", "chrX", "17") Coordinate(s): (e.g. "42101", "77119, 555911,714019")
	Alternatively, list coordinates (e.g. paste here from Excel a list of chromosome : position coordinates):
	...or upload a text file with the coordinates:
3. Specify the output format	Preferred output format: table (easier on human eyes) text (easier to parse by scripts) JSON (JavaScript Object Notation) VCF (Variant Call Format)
4.

Suggestions for improvements are most welcome.
