Add Sage converter for label-free quantification - #144
Conversation
📝 WalkthroughWalkthroughChangesThe package adds Sage LFQ support. It defines Sage input cleaning, exposes Sage conversion support
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The converter still does not handle valid annotations that omit Fraction, which can lead to incomplete converted data; the associated tests also need tighter feature-level checks and explicit fixture validation. Merge should wait for these bounded correctness and test-readiness issues to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

- Around line 136-138: Update the columns_to_fill definition in the converter to
include Fraction with a default value of 1, and add a regression test using an
annotation containing only Run, Condition, and BioReplicate to verify the
converter supplies Fraction successfully.

high_q_peptidescollapses input rows topeptideonly. The converter filters rows whoseq_valueexceeds the cutoff, so a peptide can retain signal for another charge or precursor row. The current assertions can reject valid output. ComparePeptideSequencewithPrecursorCharge(andRunwhen needed), and add a mixed-q fixture case.🤖 Prompt for AI Agents

Both fixtures are tracked package test data. If either
system.file()call returns"", the test skips all charge assertions and passes without coverage. Fail explicitly, or use a conditional skip only when this coverage is intentionally optional.🤖 Prompt for AI Agents

Motivation and Context
Sage label-free quantification data requires conversion to MSstats format. Sage
lfq.tsvfiles are not pre-filtered by FDR.This change adds Sage input cleaning and the exported
SagetoMSstatsFormatconverter. The converter supports q-value filtering and MSstats preprocessing.Changes
