Two input formats are supported: CRAVAT format and VCF format.

VCF format
See VCF specification for details.

CRAVAT format
See input format help for details.

Genomic-coordinate input format
UID, chromosome, position (1-based), strand, reference base(s), alternate base(s), and (optional) sample ID, separated by a space or tab. UID should not contain commas. For indels, use the following format. "-" means no base. Examples are below.
VAR1 chr22 25115449 + A G Sample1 (substitution)
VAR2 chr22 25115449 + - GA Sample2 (insertion)
VAR3 chr22 25115449 + GCA - Sample3 (deletion)

Transcript-coordinate input format
Variant ID, transcript identifier, amino-acid substitution, and (optional) sample ID, separated by a space or tab. An example is below.
VAR4 NP_001135977 R641W 1 (substitution)
