**What it does**

This tool identifies and masks out low complexity regions of a nucleotide database (or sequences in FASTA format) by using the symmetric DUST_ algorithm.

If you select *maskinfo ASN.1* (binary or text) as output format, the output file can be used as masking data for NCBI BLAST+ makeblastdb tool.

More information about dustmasker can be found in the `BLAST Command Line Applications User Manual`_.
