OSfinder assumes that anchor files have the form shown below when two genomes (G1 and G2) are compared.
chrom_1 start_1 end_1 sign_1 chrom_2 start_2 end_2 sign_2 chrom_1 -- chromosome ID on genome G1 (int). start_1 -- start coordinate on genome G1 (int). end_1 -- end coordinate on genome G1 (int). sign_1 -- orientation on genome G1 (char). chrom_2 -- chromosome ID on genome G2 (int). start_2 -- start coordinate on genome G2 (int). end_2 -- end coordinate on genome G2 (int). sign_2 -- orientation on genome G2 (char). Example) 1 8040363 8040427 + 1 168782735 168782799 + 1 8847983 8848048 + 1 43731182 43731247 - 1 8849080 8849144 + 1 43730882 43730946 - 1 8876198 8876273 + 1 108267190 108267265 +
Note that Chromosome IDs, start coordinates and end coordinates must be integer. Thus, "X" and "Y" are not appropriate for chromosome ID. In our experiment, we used "-1", "-2", "-3", and "-4" instead of "X", "Y", "2a", "2b", respectively.
