Bifurcator by Ben Fry | Download Revision 21 This application creates a bifurcation plot from a set of haplotype data. Given a set of SNPs that define a "core" region, a tree is produced that shows how the genotypes of a set of individuals bifurcate and differentiate themselves from that point. usage: [--actual-positions] [--less-text] <phased_file> <position_file> <core_position> <core_length> <left_branch_length> <right_branch_length> <font_size> Example: java -jar bifurcator.jar ceph3.phase ceph3.pos 32 1 10 10 5 (the download includes the input files for this example) --actual-positions will horizontally place SNPs based on genomic position instead of equidistant --less-text this options shuts of text for anything except for the core region. The <phased_file> parameter should be a file that contains phased haplotype data. The first two columns of the data are ignored. Additional columns are expected to contain 1, 2, 3, or 4 to signify A, C, G, or T. The <position_file> parameter should specify a file that lists the position of each SNP on its own line.
