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.

WebJun 24, 2024 · The typical way to write an ASCII .fastq is done as follows: for record in SeqIO.parse (fasta, "fasta"): SeqIO.write (record, fastq, "fastq") The record is a SeqRecord object, fastq is the file handle, and "fastq" is the requested file format. The file format may be fastq, fasta, etc., but I do not see an option for .gz. Here is the SeqIO API. A quality value Q is an integer mapping of p (i.e., the probability that the corresponding base call is incorrect). Two different equations have been in use. The first is the standard Sanger variant to assess reliability of a base call, otherwise known as Phred quality score: The Solexa pipeline (i.e., the software delivered with the Illumina Genome Anal…

Webfastp evaluates the read number of a FASTQ by reading its first ~1M reads. This evaluation is not accurate so the file sizes of the last several files can be a little differnt (a bit bigger or smaller).
