Description

This track depicts masked sequence as determined by WindowMasker on the the 29 Jun 2021 Eueides isabella/GCA_019049475.1_ASM1904947v1/GCA_019049475.1 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.

Methods

To create this track, WindowMasker was run with the following parameters:

windowmasker -mk_counts true -input GCA_019049475.1_ASM1904947v1.unmasked.fa -output wm_counts
windowmasker -ustat wm_counts -sdust true -input GCA_019049475.1_ASM1904947v1.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.bed
The 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 214,013,151 bases in the assembly size 440,123,586 for a percent coverage of % 48.63.
