Fastq to Fasta Sequence Converter

Input format: fastq FASTQ files are a bit like FASTA files but also include sequencing qualities. In Biopython, 'fastq' refers to Sanger style FASTQ files which encode PHRED qualities using an ASCII offset of 33. See also the incompatible 'fastq-solexa' and 'fastq-illumina' variants.

Output format: fasta This refers to the input FASTA file format introduced for Bill Pearson's FASTA tool, where each record starts with a '>' line. Resulting sequences have a generic alphabet by default.

You can also convert between these formats by using command line tools.

On Windows install WSL, on Mac or Linux start terminal

Install BioPython

Run following script:

from Bio import SeqIO

records = SeqIO.parse("THIS_IS_YOUR_INPUT_FILE.fastq", "fastq")
count = SeqIO.write(records, "THIS_IS_YOUR_OUTPUT_FILE.fasta", "fasta")
print("Converted %i records" % count)
