WebJun 1, 2024 · Since the majority of variant callers require mapping reads to a reference genome, the reliability of the latter is a key factor determining accuracy of the downstream analyses. We present Whisper 2, a short-read-mapping software providing superior quality of indel variant calling. Its running times place it among the fastest existing tools. Webread mapping and variant calling. For read mapping, we adopt a divide-and-conquer strategy to separate a read into regions with and without gapped alignment. With this strategy of read partitioning, SNVs, indels, and breakpoints can be identified efficiently. For variant calling, MapCaller maintains a position
