This track depicts masked sequence as determined by WindowMasker on the the 16 Jun 2010 Coprinopsis cinerea okayama7#130/GCA_000182895.1_CC3/GCA_000182895.1 genome assembly. The WindowMasker tool is included in the NCBI C++ toolkit. The source code for the entire toolkit is available from the NCBI FTP site.
To create this track, WindowMasker was run with the following parameters:
windowmasker -mk_counts true -input GCA_000182895.1_CC3.unmasked.fa -output wm_counts windowmasker -ustat wm_counts -sdust true -input GCA_000182895.1_CC3.unmasked.fa -output windowmasker.intervals perl -wpe 'if (s/^>lcl\|(.*)\n$//) { $chr = $1; } \ if (/^(\d+) - (\d+)/) { \ $s=$1; $e=$2+1; s/(\d+) - (\d+)/$chr\t$s\t$e/; }' windowmasker.intervals > windowmasker.sdust.bedThe windowmasker.sdust.bed included masking for areas of the assembly that are gap. The file was 'cleaned' to remove those areas of masking in gaps, leaving only the sequence masking. The final result covers 2,826,914 bases in the assembly size 36,192,590 for a percent coverage of % 7.81.
