WebMay 1, 2024 · We choose bwa-meth for alignment as it provides efficient and robust mappings due to its internal usage of BWA-MEM . We omit pre-alignment trimming of reads because of bwa-meth’s internal usage of soft-clipping to mask non-matching read subsequences. Alignments are deduplicated using the Picard toolkit . WebNov 25, 2024 · This tool provides simple, powerful read clipping capabilities that allow you to remove low quality strings of bases, sections of reads, and reads containing user-provided sequences. There are three arguments for clipping (quality, position and sequence), which can be used alone or in combination. trska za ogradu kupujem prodajem
