Approximate Hashing for Bioinformatics

The paper extends ideas from data compression by deduplication to the Bioinformatic field. The specific problems on which we show our approach to be useful are the clustering of a large set of DNA strings and the search for approximate matches of long substrings, both based on the design of what we call an approximate hashing function. The outcome of the new procedure is very similar to the clustering and search results obtained by accurate tools, but in much less time and with less required memory.
