Description
This track depicts masked sequence as determined by WindowMasker on the
the 24 Jan 2022 Homo sapiens/GCA_009914755.4_T2T-CHM13v2.0/GCA_009914755.4 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_009914755.4_T2T-CHM13v2.0.unmasked.fa -output wm_counts
windowmasker -ustat wm_counts -sdust true -input GCA_009914755.4_T2T-CHM13v2.0.unmasked.fa -output windowmasker.intervals
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 1,297,712,987 bases in the assembly size 3,117,292,070 for
a percent coverage of % 41.63.
