CORE CAPABILITY

Alignments + QC

MolBioCove aligns Sanger traces and FASTQ/consensus reads back to the expected construct sequence, calls mismatches automatically, and pins evidence (trace, quality, allele fraction) to the exact bases—so you can confirm true variants, ignore noise, and keep QC decisions reviewable. Local-first, natively built on macOS.

PRODUCT VIEW

Sanger mismatch detection with coding impact

Automatic calls highlight what changed—and whether it affects the coding sequence—so you can focus on the mismatches that matter.

MULTIPLE SEQUENCE ALIGNMENT

AlignCove: deterministic MSA for remote‑homology proteins

AlignCove is MolBioCove’s default protein multiple‑sequence alignment (MSA) engine, tuned for challenging remote‑homology families. It’s deterministic by design (same input → same output), so results are reproducible and easy to compare across runs and collaborators. No ML inference—fully algorithmic and deterministic.

How it works (high level)

  1. Input normalization + QA
  2. Difficulty stats (sequence count, lengths, similarity)
  3. Guide tree from k‑mer distances (k=6)
  4. Progressive alignment (sequence↔sequence, sequence↔profile, profile↔profile; affine‑gap DP)
  5. Pairwise rescue candidates (only for the final two‑sequence merge)
  6. Stage‑3 refinement (bounded local search; deterministic tie‑breaks)
  7. Output + diagnostics (final alignment + run metadata)

AlignCoveV1 is the stable shipping preset. Today, aligncove and aligncove‑v1 produce identical results for the same input (and remote7 is a historical alias).

When AlignCoveV1 collapses to a final two‑sequence merge, it can evaluate a small, deterministic set of “rescue” candidates (e.g. diagonal‑biased DP and terminal‑gap rebalance). A rescue is used only if it improves the unbiased score and passes safety checks (to avoid pathological alignments).

Benchmarks (alignment quality; quality‑only)

On a curated set of 13 difficult OXBench families (SP‑F1; higher is better):

  • AlignCoveV1 mean SP‑F1: 0.6337
  • Best external tool per family (mean SP‑F1): 0.7053 (gap: 0.0715)

External tool mean SP‑F1 (same set):

  • T‑Coffee: 0.6758
  • ProbCons: 0.6620
  • MUSCLE: 0.6587
  • MAFFT: 0.6572
  • Clustal Omega: 0.6511
  • MSAProbs: 0.5822

Note: this comparison is quality‑only; it does not include external tool runtimes.
