SNP density 100kb windows (28,442)

dbSNP 126 has 12million SNPs, including randoms , etc.The region with the most SNPs is chr16 44943302-45043302

Regions with no SNPs (100kb)

• Watson and Venter have 121 regions in common (292 & 162)

• All HapMap has 444 in common (469-487)• They all have 111 in common– dbSNP has entries in these regions– Ensembl has a few Watson SNPs and many Venter

SNPs (only 2 in chrY remained 0) here

Genome Graphs import uses a 10kb window for computing depth and coverage. For these graphs depth was chosen and connections were drawn between items up to 1mb away. Ceu was done with both 1mb connections and 10kb connections and there wasn’t a noticeable difference.
