Raincloud plot of neurite length in three genotypes — half violin, box and every individual neuron — so a bimodal knockout is seen rather than averaged away. Typed FlowScript for laboratory biology. Keywords: experiment, assay, sample, protocol.

FlowScriptACMG/AMP 2015 — sequence variant classification rules
The ACMG/AMP 2015 germline sequence-variant classification framework — the 16 pathogenic evidence codes (PVS1, PS1–PS4, PM1–PM6, PP1–PP5), the 12 benign codes (BA1, BS1–BS4, BP1–BP7) and the Table 5 combining rules that map them onto pathogenic, likely pathogenic, uncertain significance, likely benign and benign — the rule set a clinical molecular geneticist applies to every variant before it is reported.
Graphviz (DOT)Phase I oncology — 3+3 dose escalation and MTD rules
The 3+3 dose-escalation decision rules for a first-in-human phase I oncology trial — the CTCAE v5.0 dose-limiting toxicity definition, the 0/3, 1/3 and ≥2/3 cohort decisions, expansion to six patients, de-escalation, the MTD definition (≤1 DLT in 6 evaluable patients) and the RP2D expansion cohort — the escalation schema every phase I protocol and DSMB charter must state.
Graphviz (DOT)Levey-Jennings chart — glucose QC with a 2-2s rejection
Levey-Jennings internal quality control chart for a clinical chemistry analyte: twenty daily QC results plotted against an assigned mean and cumulative SD with +/-1s, +/-2s and +/-3s limits, showing the 1-2s warning at run 14 and the 2-2s systematic-error rejection completed at run 15 — the chart a medical laboratory scientist reviews and signs before releasing any patient result.
PlotCausal perturbation — loss, rescue and controls
Plan a gene-function experiment that separates association, loss-of-function and rescue. Include delivery controls and independent readouts; rescue supports specificity but does not eliminate every off-target explanation.
ScienceSingle-cell study — samples before cell counts
Design a single-cell analysis without treating cells from one donor as independent biological replicates. Track sample identity through quality control, annotation and donor-level comparisons.
ScienceOrganoid model — identity, function and limits
Validate an organoid model against predefined identity and functional criteria. Distinguish technical repeat wells from independent donor lines and make the limits of in-vitro extrapolation explicit.
ScienceMicrobiome workflow — contamination and compositionality
Map a sequencing study with field blanks, extraction blanks and batch randomisation. Relative abundance is compositional; absolute microbial load requires a separately justified measurement.
ScienceReceptor signalling — response and adaptation
A generic receptor-signalling model distinguishes ligand binding, signal amplification and termination. Feedback and receptor trafficking can alter response duration; arrows specify regulation rather than material transfer.
ScienceStable-isotope tracing — flux inference boundaries
Plan isotope tracing with a labelled input, time points, metabolite pools and isotopologue distributions. Enrichment alone is not flux; inference requires a network model and justified steady-state assumptions.
ScienceAntibody validation — orthogonal evidence
Select validation strategies for the intended assay, including genetic controls, independent antibodies and orthogonal measurements. A validation in one application does not automatically transfer to another.
ScienceCell migration assay — motility versus proliferation
Interpret wound closure with time-resolved imaging, viability and proliferation controls. Separate collective migration from growth and use independent cultures as the unit of replication.
ScienceHost–pathogen model — exposure, burden and response
A conceptual infection-study map distinguishes exposure, pathogen burden, host response and damage. Use appropriate containment and approved protocols; this template specifies measurements rather than operational pathogen-handling steps.
ScienceSpecies occupancy — presence versus detection
Repeated site visits help separate occupancy from imperfect detection. Keep site covariates distinct from visit-level conditions and report uncertainty rather than interpreting every non-detection as absence.
ScienceFood web — perturbation and indirect effects
Explore a small conceptual food web with resource limitation, predation and a perturbation. Arrow captions distinguish consumption from effects; the diagram is a hypothesis map, not a quantified stability analysis.
ScienceCircadian study — phase, amplitude and environment
Separate clock phase from response amplitude using time-series observations and controlled timing. Record light, feeding and sampling schedules; distinguish entrainment from a single treatment response.
ScienceLineage tracing — ancestry versus cell state
Track a heritable label through cell divisions while measuring phenotype separately. Clonal ancestry, current marker expression and inferred fate are different claims; label specificity and detection losses constrain interpretation.
ScienceImmune memory — primary and recall responses
Compare primary activation, contraction and recall in a conceptual immune-response model. Antibody titres, memory-cell frequencies and functional protection are separate readouts and should not be treated as interchangeable.
ScienceSpatial transcriptomics — location and mixture
Combine tissue location, expression and morphology while retaining spot-level uncertainty. Mixed-cell capture areas require explicit deconvolution assumptions; proximity alone does not establish cell-to-cell signalling.
ScienceReplication design — biological and technical units
Distinguish experimental allocation units, independent biological samples and repeated technical measurements. Aggregate or model technical repeats appropriately rather than inflating the biological sample count.
ScienceExperimental bias — allocation, masking and audit
Build a study workflow that keeps allocation generation, intervention delivery and outcome assessment distinct. Record unavoidable unmasking and analyse according to a predefined plan.
SciencePlant stress — water status, growth and recovery
Compare plant responses during stress and after recovery. Water status, stomatal behaviour and biomass are distinct endpoints; position, developmental stage and independent plants constrain the design.
ScienceProteomics — peptide evidence to protein inference
Trace quantitative proteomics from independent samples through peptide identification and protein inference. Shared peptides, missing values and batch effects must remain visible in downstream comparisons.
ScienceMechanobiology — substrate to cellular response
Relate substrate mechanics and ligand presentation to cell adhesion, force generation and response. Changes in stiffness can be confounded by chemistry or geometry, so define matched controls.
