Features

• Compares the snps in two or more VCF files.

• Lists the snps that are unique to each VCF file with full genotype information per snp.

• Lists the snps that are missing from each VCF file if present in at least two other VCF files.

• Generates Venn diagrams of positions and snps in the VCF files.

• Reports precision, recall, and F1 score when the truth is known.

• Reports the effectiveness of filtered variants when the truth is known.

• Reformat the VCF file in a tall-narrow format for easy viewing and diffs.

• Count samples, positions, calls, snps, indels, other variants, missing calls, and filter reasons.

• Plot calls along the length of the genome and show the location of filtered calls.

• Add the plot command to plot calls along the length of the genome and show the location of filtered calls.

• Change the text of the compare report to refer to “Calls”, not “Sample snps”.
