Ig to Fastq Sequence Converter

Input format: ig This refers to the IntelliGenetics file format, apparently the same as the MASE alignment format.

Output 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.

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

On Windows install WSL, on Mac or Linux start terminal

Run following script:

from Bio import SeqIO

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