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.
