Version Compatibility

Reference examples tested with: BioPython 1.83+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

FASTQ Quality Scores

"Filter my FASTQ reads by quality score" → Access, analyze, and filter Phred quality scores, trim low-quality bases, and generate per-position quality profiles.

• Python: SeqIO.parse() with letter_annotations['phred_quality'] (BioPython)

Analyze and manipulate FASTQ quality scores using Biopython.
