Kmer-indexer: A Fast K-mer Indexing Program.

In our previous work, a k-mer based program named MFEprimer-2.0 was designed and developed for primer specificity evaluation task. In order to increase the index processing speed, decrease the index data size and memory usage, we developed a new program named kmer-indexer. Compared to MFEprimer-2.0, the processing speed of kmer-indexer is 10+ times faster, the index data size can be significantly reduced to one third, and the memory usage is controlled within a small range so that this program can run on an ordinary PC.
