linkmapper 0.2.0
A rewrite of the app as a modular package.
New
- Backcross and recombinant inbred line populations, alongside F2 intercrosses; onemap raw files as well as MAPMAKER.
- Trait files in CSV, in addition to traits in the genotype file.
- Segregation tests with Bonferroni correction, missing-data summaries and marker filters.
- Seriation ordering, Haldane distances, and recombination-fraction heatmaps per linkage group.
- Interactive linkage map with QTL support intervals; MapChart, CSV and Excel exports.
- QTL mapping with R/qtl: Haley-Knott, EM or imputation interval mapping and composite interval mapping, permutation thresholds, 1.5-LOD support intervals, variance explained, effects and genotype plots.
- HTML report, reproducible R script and session files; PNG, SVG and PDF for every figure.
- Horizontal step bar, guided tour, dark mode and its own visual identity.
read_cross(), qc_summary(), filter_markers(), linkage_groups(), order_groups(), build_cross(), scan_qtl(), run_analysis() and related functions are exported.
Fixed
- Analysis state was held in global variables, so sessions on the hosted app could interfere with each other.
- The QTL step did not detect QTL on the demo data.
- The map image was written to the working directory.
- Marker ordering was not reproducible between runs.
Compatibility
run_linkmapper(), validate_lm_file() and group_markers() keep their 0.1 behaviour.
