Motivation and Context

Please include relevant motivation and context of the problem along with a short summary of the solution.

Changes

Please provide a detailed bullet point list of your changes.

Testing

Please describe any unit tests you added or modified to verify your changes.

Checklist Before Requesting a Review

  • I have read the MSstats contributing guidelines
  • My changes generate no new warnings
  • Any dependent changes have been merged and published in downstream modules
  • Ran styler::style_pkg(transformers = styler::tidyverse_style(indent_by = 4))
  • Ran devtools::document()

Motivation and Context

annotateProteinInfoFromIndra did not support protein groups represented by semicolon-joined identifiers. The function now resolves each group member independently and pools the results onto the original row.

Changes

  • Added helpers to split, join, and normalize protein-group identifiers.
  • Added PTM site suffix removal for each group member.
  • Updated UniProt, INDRA COGEX, and Gilda grounding paths to:
    • Resolve members independently.
    • Deduplicate results.
    • Preserve member order.
    • Store pooled results as semicolon-joined values.
  • Initialized Entity columns as NA_character_.
  • Updated gene-flag population to skip rows with multiple groundings.
  • Updated documentation for protein-group behavior and multi-grounded rows.

Unit Tests

  • Added tests for protein-group splitting, joining, and PTM site removal.
  • Added tests for per-member UniProt and COGEX resolution.
  • Added tests for pooling, deduplication, shared-gene collapse, and unresolved members.
  • Added tests for separate COGEX query nodes.
  • Added mocked API calls for protein-group grounding paths.

Coding Guidelines

No coding guideline violations are identified in the provided changes.

📝 Walkthrough

Walkthrough

Changes

Protein-group inputs are split on semicolons, normalized, PTM-stripped, and grounded per member. UniProt, COGEX, and Gilda results are deduplicated and pooled into aligned Entity columns. Gene flags remain unset for multi-grounded rows. Tests and documentation cover the new behavior.

Group parsing and UniProt resolution
R/annotateProteinInfoFromIndra.R, tests/testthat/test-annotateProteinInfoFromIndra.R, man/annotateProteinInfoFromIndra.Rd, man/dot-populateUniprotIdsInDataFrame.Rd
The code splits protein groups, strips PTM suffixes per member, resolves UniProt IDs, and joins results with semicolons.
Pooled entity grounding

COGEX and Gilda ground each member independently, deduplicate results, and populate aligned Entity columns. Tests cover unresolved members, repeated members, metabolites, and COGEX fan-out.
Single-gene flag handling
R/annotateProteinInfoFromIndra.R, man/dot-populateKinaseInfoInDataFrame.Rd, man/dot-populatePhophataseInfoInDataFrame.Rd, man/dot-populateTranscriptionFactorInfoInDataFrame.Rd
Transcription-factor, kinase, and phosphatase flags skip rows with multiple groundings. Single-grounding rows retain flag population.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 857a3

Protein-group annotation can still produce incorrect UniProt or Gilda mappings when existing GlobalProtein values are reused or identifiers are stripped too broadly; the PR is mergeable with explicit owner awareness and follow-up to correct these bounded mapping risks.

UniProt and Gilda join the train
COGEX maps the links again

Match only a complete trailing PTM suffix.

The current patterns match _[A-Z][0-9] anywhere in the identifier. For example, ABC_S1_extra becomes ABC even though it has no trailing PTM suffix. This can ground the wrong group member.

Proposed fix
 .stripPtmSite <- function(x) {
-        return(ifelse(grepl("_[A-Z][0-9]", x),
-                      gsub("_[A-Z][0-9].*", "", x, perl = TRUE),
-                      x))
+        return(gsub("_[A-Z][0-9]+$", "", x, perl = TRUE))
 }

Always derive GlobalProtein from Protein.

When input already contains GlobalProtein, this branch skips per-member PTM stripping. Downstream UniProt and Gilda mapping then uses stale or unnormalized values instead of the current Protein group. Derive and overwrite GlobalProtein for every row.
