Efficient sequence alignment against millions of prokaryotic genomes with LexicMap

Probe generation Probes, also referred to as ‘masks’ in the LexicHash paper, consist of a fixed number (m = 20,000 by default) of k-mers (k ≤ 32, k = 31 by default), which capture DNA sequences by prefix matching. A probe consists of two parts—the p-bp prefix and the remaining bases. To enable probes to match all possible reference and query sequences by prefix matching, all …
