The files in this directory contain the information about locations and spanning lengths of single and consecutive molossinus and musculus-diagnostic SNPs, which specify each of four subspecies-derived strains, WSB/EiJ (domesticus), CAST/EiJ (castaneus), PWD/PhJ (musculus), and MSM/Ms (molossinus), using the combined data of the NIEHS project (K. A. Frazer et al. Nature 448, 1050, 2007) and the MSM/Ms sequence. File names are formatted as src_blk_{chromosome}_{strain-name}.xls Fields are : source strain: intrgression source strain, MSM(molossinus) or PWD(musculus) chr. start: start b.p. of introgression block chr. end: end b.p. of introgression block block len.: length of introgression block SNP num.: the number of SNPs that countruct this block mode: mode of introgression
