WebJun 29, 2024 · It's difficult to get this to go massively quicker I think - as with this question working with large gzipped FASTQ files is mostly IO-bound. We could instead focus on making sure we are getting the right answer.. People deride them too often, but this is where a well-written parser is worth it's weight in gold. WebSep 25, 2009 · For example, suppose you have a Solexa FASTQ file where you want to trim all the reads, taking just the first 21 bases (say). Why might you want to do this? Well, in Solexa/Illumina there is a general decline in read quality along the sequence, so it can make sense to trim, and some algorithms like to have all the input reads the same length.
WebThis tutorial teaches a fast approach to how to read sequences from large FASTA files in Python using Pysam.
