This track depicts masked sequence as determined by
WindowMasker tool is included in the NCBI C++ toolkit. The source code
for the entire toolkit is available from the NCBI
To create this track, WindowMasker was run with the following parameters:
windowmasker -mk_counts true -input mm39.fa -output wm_counts
windowmasker -ustat wm_counts -sdust true -input mm39.fa -output repeats.bed
The repeats.bed (BED3) file was loaded into the "windowmaskerSdust" table for
Morgulis A, Gertz EM, Schäffer AA, Agarwala R.
