Practical sequence analysis, comparison, generation, and reproducible testing workflows for computational biology.
Find a method, workflow, scientific concept, or software decision.
Learn how a sequence dot plot works, what diagonal patterns can suggest, how window and threshold settings affect noise and sensitivity, and when to follow the visual pattern with an alignment.
Supports Dot Plot Read the analysisFilter the publication by research area or keyword.
Evidence-led articles on scientific methods, reproducible workflows, and software decisions.
Learn when local protein alignment is more appropriate than an end-to-end comparison, how Smith-Waterman defines the matching region, and how to interpret score, coordinates, identity, and gaps without overclaiming.
Learn when end-to-end protein alignment is appropriate, how it differs from local alignment, why substitution matrices and gap penalties change the result, and how to interpret score and identity responsibly.
Choose the right random-sequence model, distinguish uniform generation from shuffling, preserve the generated FASTA and metadata, and avoid treating synthetic controls as natural proteins.
