A Fast and Symmetric DUST Implementation to Mask Low-Complexity DNA Sequences

Aleksandr Morgulis, E. Michael Gertz, Alejandro A. Schäffer, Richa Agarwala
2006 Journal of Computational Biology  
The DUST module has been used within BLAST for many years to mask low-complexity sequences.  ...  In this paper, we present a new implementation of the DUST module that uses the same function to assign a complexity score to a sequence, but uses a different rule by which high-scoring sequences are masked  ...  One would like masking of low-complexity sequences to be as fast and as predictable as possible.  ...
