Capstone Evidence Guide & Rubric
How to know when your binder-design project is complete—and defensible
Purpose
The capstone is not complete merely because every command ran. A strong submission makes a reproducible, evidence-based argument for why one design should move forward and why the alternatives should not.
Use this page at three points:
- Before starting, to plan what you will save.
- At each milestone, to check whether your evidence is sufficient.
- Before finishing, to self-assess the complete project.
Required Evidence Portfolio
Your final format can be a report, notebook, repository, slide deck, or video, but it should contain all seven artifacts below.
1. Target and epitope brief
- Target name, biological role, structure accession, chain, and residue range
- The binding surface or epitope you intend to target
- Three to six hotspot residues and the evidence used to choose them
- Important caveats such as missing density, glycosylation, alternate conformations, cofactors, or chain-numbering differences
Completion evidence: one annotated structure image plus a concise rationale.
2. Reproducible run configuration
- Tool release or commit, environment, model checkpoint, and hardware
- Exact input-file identifiers and checksums when practical
- Commands, configuration files, random seeds, and output paths
- Any deviations from the course’s known-good stack
Completion evidence: another learner could reconstruct the run without guessing hidden settings.
3. Backbone-generation evidence
- Number and type of designs generated
- Representative gallery showing both successful and failed outputs
- Topology, target contact, hotspot contact, clashes, and diversity observations
- A documented first-pass filter
Completion evidence: a gallery or table that explains why candidates were kept or removed.
4. Sequence-design evidence
- Sequence-design method and settings
- Number of sequences generated per backbone
- Sequence recovery, diversity, composition, and any fixed residues
- Checks for obvious liabilities relevant to your target or intended use
Completion evidence: a compact candidate table linking sequences back to their parent backbones.
5. Structural validation
- Complex-prediction method and settings
- Per-chain confidence, interface confidence, and PAE interpretation
- Interface geometry, hotspot recovery, clashes, and model agreement
- At least one independent check beyond a single confidence score
Completion evidence: figures and metrics that distinguish local fold confidence from interface confidence.
6. Failure analysis and iteration
- At least one failed or misleading result
- Your diagnosis of the likely cause
- The change you made in response
- Whether the next run supported your diagnosis
Completion evidence: a short before/after comparison. A scientifically useful failure is stronger evidence than an unexplained success.
7. Final selection memo
- The candidate you would advance and the alternatives you rejected
- The criteria and trade-offs behind that decision
- Remaining uncertainty and the next computational or experimental test
- A clear statement that computational confidence is not experimental validation
Completion evidence: a one-page decision memo or equivalent final section.
Twenty-Point Self-Assessment Rubric
Score each category from 1–4. Use the lowest description that still fits the work consistently.
A. Reproducibility
- 4 — Reconstructable: inputs, versions, commands, seeds, outputs, and deviations are complete and internally consistent.
- 3 — Mostly reproducible: the main run can be repeated, but one or two minor details require inference.
- 2 — Partially documented: settings are summarized, but exact inputs or commands are missing.
- 1 — Not reproducible: results cannot be connected reliably to a specific configuration.
B. Structural and computational evidence
- 4 — Converging evidence: multiple appropriate metrics and visual checks support the conclusions, with limitations interpreted correctly.
- 3 — Adequate evidence: core confidence and interface checks are present, but validation is narrow.
- 2 — Score-driven: conclusions rely primarily on one summary score or an attractive structure image.
- 1 — Unsupported: outputs are shown without meaningful validation.
C. Scientific judgment
- 4 — Defensible decisions: selection criteria are explicit, trade-offs are weighed, failures are investigated, and uncertainty changes the conclusion appropriately.
- 3 — Reasonable decisions: choices are explained and major limitations are acknowledged.
- 2 — Descriptive decisions: observations are listed, but the reasoning connecting them to selection is weak.
- 1 — Completion-based: a candidate is selected mainly because the pipeline produced it.
D. Iteration and learning
- 4 — Hypothesis-driven iteration: a failure or comparison motivates a specific change that is then evaluated.
- 3 — Documented iteration: multiple settings are compared and their effects are discussed.
- 2 — Repetition without diagnosis: several runs are shown, but changes are not tied to a clear hypothesis.
- 1 — Single pass: no meaningful iteration or failure analysis is included.
E. Communication
- 4 — Clear evidence trail: figures, tables, labels, captions, and narrative allow a reader to follow the complete argument efficiently.
- 3 — Understandable: the story is coherent with only minor gaps or presentation problems.
- 2 — Fragmented: key outputs exist, but their relationships or significance are hard to follow.
- 1 — Incomplete: essential artifacts or explanations are absent.
Interpreting Your Score
- 17–20: Portfolio ready. The work presents a defensible computational argument and clearly identifies what remains unproven.
- 13–16: Complete with revisions. Strengthen the lowest-scoring category before presenting or sharing the work.
- 9–12: Pipeline run, not yet a scientific case. Add missing evidence, comparison, and decision logic.
- 5–8: Reconstruct the evidence trail. Confirm inputs and outputs before drawing conclusions.
For course completion, aim for at least 13/20, with no category below 2. The score is a self-assessment aid—not evidence that a binder will work experimentally.
Suggested Review Sequence
- Review your target brief before spending substantial compute.
- Review reproducibility and backbone evidence before sequence design.
- Review sequence and validation evidence before selecting a finalist.
- Complete the rubric and revise the lowest category.
- Compare your reasoning with the worked selection example.
