Pair-end reads翻译
WebReads that start or end with very low quality can be aligned better if the bad quality parts are trimmed off. We will use Trimmomatic to trim reads and remove adapter sequences. As we have paired reads, we will run it in Paired-end (PE) mode which requires 2 input files (for forward and reverse reads) and 4 output files (for forward paired, forward unpaired, … WebMay 9, 2024 · My comment above mentions the slow IO for the Python code (it was iterating at ~ 3600 reads/s, which, for a FASTQ with 500M reads would take ~1.6 d to complete), so I tried an alternative method that would cut down on the IO overhead. It's not super efficient, but I ended up using zcat awk with a switch-case on the line number to stream the data.
