WebThese polyG tails need to be removed or the read will not map well to the reference genome. Reads that start or end with very low quality can be aligned better if the bad quality parts are trimmed off. We will use fastp to fix all of these issues. fastp can remove low quality reads, adapters and polyG tails. It even automatically detects what ...
