Question 1

Why use a workflow manager rather than shell scripts?

Accepted Answer

Workflow managers handle dependency resolution, parallel execution, resumption after failure and portability across computing environments without rewriting job submission logic. Scripts work until a run fails midway through hundreds of samples. The declarative structure also documents the analysis graph, which serves as part of the methods description.

Question 2

How is reproducibility actually achieved?

Accepted Answer

Pin every tool to an exact version inside a container image or a fully specified environment, record parameters and reference genome builds per run, and place the workflow under version control with a tagged release for each published result. Reproducibility means someone else obtains identical output later, not that your machine produces it twice.

Question 3

What makes a fair benchmark?

Accepted Answer

Use evaluation data whose correct answers were established independently, whether simulated with known ground truth or reference samples with community truth sets. Report sensitivity and precision across a range of thresholds rather than one operating point, and tune competing methods with equal effort, since undertuned comparisons are the commonest weakness in method papers.

Question 4

How much testing does a research pipeline need?

Accepted Answer

At minimum, a small end-to-end dataset that runs in minutes and confirms every step still executes and produces expected output shapes. Unit tests on custom scripts catch logic errors early. Running these automatically on each change reveals breakage when a dependency shifts, which otherwise surfaces months later in a rerun.

Question 5

How are parameter choices justified?

Accepted Answer

Defaults reflect the developer test case, not your organism, read length or coverage. Vary the parameters that plausibly matter across a realistic range and report how results move. Where conclusions prove sensitive to a setting, that sensitivity belongs in the thesis rather than being hidden behind one chosen value.

Question 6

How should compute and storage be planned?

Accepted Answer

Estimate memory and runtime per step from a pilot batch, since one memory-hungry step usually sets the requirement for the whole run. Decide early which intermediate files are kept and which are regenerated on demand, because storage rather than processing time is often the binding constraint on large cohorts.

Question 7

What should be released alongside the thesis?

Accepted Answer

Publish the workflow code with a licence, container definitions, parameter configuration files and a small test dataset, and archive a citable snapshot with a persistent identifier. Documenting expected inputs, outputs and resource requirements determines whether anyone reuses the work or rebuilds it from scratch.
