docs: optional environment fields in the bug form; the clr_welch settings in the README - #145
Conversation
…ings in the README Both CodeRabbit findings from #143, accepted; the PR merged before the fixes could ride on it, so they land here. - The bug report form required R and browser versions from everyone: a command-line reporter has no browser to name, and a web-interface reporter often cannot know the server's R version, so both fields forced placeholder answers. They are now optional, each with the wording that says when it applies; Julia stays required, since every reporter runs the Julia server. - The differential-abundance README section described only the default nb_glm method and listed only offset and min_prevalence, presenting the analysis as NB-only; clr_welch and replacement_delta have been in the pipeline config and code since the upstream syncs. The section now documents method and replacement_delta, notes that offset applies to nb_glm only, and states clr_welch's effect as a CLR difference, not a fold change. The wording follows config/defaults/pipeline.yml's own comments for the same keys. Generated by Mistral Vibe. Co-Authored-By: Mistral Vibe <vibe@mistral.ai>

Review comments at @README.md:
- Around line 268-270: Update the README volcano-plot description to state that
`nb_glm` plots log2 fold change while `clr_welch` plots the CLR difference;
retain the shared raw p-value axis and adjusted-p-value colouring description.
- Around line 268-270: Update the refusal list in the README to include
unsupported method values, replacement_delta values outside (0, 1), clr_welch
groups with fewer than two samples, and cases where zCompositions cannot be
loaded. Clarify that the documented three-sample minimum does not prevent a 1+2
split from failing the per-group requirement.

Describe the volcano-plot axis by method.
The plot uses the method-specific effect key and label. Update the README because it currently states that every plot uses log2 fold change.
Suggested documentation fix
-The result is a volcano plot and a table. The plot draws log2 fold change
-against -log10 of the raw p-value, coloured by whether the adjusted p-value
-is below 0.05.
+The result is a volcano plot and a table. For `nb_glm`, the plot draws log2

Complete the failure conditions for the new settings.
The refusal list should also include unsupported method values, replacement_delta values outside (0, 1), fewer than two samples in either group for clr_welch, and unavailable zCompositions. A 1+2 group split passes the documented three-sample minimum but then fails the clr_welch per-group check.
