scRepertoire VERSION 2.7.2

NEW FEATURES

  • New clonalBin() function to bin clones by frequency or proportion without requiring a single-cell object. Adds clonalFrequency, clonalProportion, and cloneSize columns to the output of combineTCR(), combineBCR(), or combineExpression(). Supports custom bin thresholds, optional grouping by metadata variable, and chain filtering.
  • New vizCirclize() function for quick chord diagram visualization without manual circlize code. Supports directional arrows, custom colors, and sector annotations.
  • getCirclize() major enhancements:
    • Multi-level hierarchical grouping via group.by accepting a vector of columns
    • New method parameter: "unique", "abundance", "jaccard", "overlap"
    • New symmetric parameter for directional flow analysis
    • New include.metadata parameter returning sector statistics
    • New filtering options: min.shared, top.links, filter.sectors
    • Built-in color palette generation with palette parameter
  • alluvialClones() major enhancements:
    • New top.clones, min.freq, highlight.clones, and highlight.color parameters
    • Visual customization: stratum.width, flow.alpha, show.labels, label.size
    • New order.strata parameter for controlling level ordering within each stratum
    • Enhanced export.table output now includes freq, prop, and rank columns
  • combineBCR() defaults the clustering call to “IGH” instead of “both”

API CHANGES

  • Soft-deprecated camelCase arguments across all exported functions in favor of dot.notation (e.g., cloneCall to clone.call, exportTable to export.table, cloneSize to clone.size, filterNA to filter.na, addLabel to add.label, clonalSplit to clonal.split). All deprecated arguments will continue to work with a deprecation warning until version 3.0.0.

BUG FIXES

  • Fixed combineExpression() failing with “undefined columns selected” when input data already contained clonalFrequency/clonalProportion columns from a prior clonalBin() call.

scRepertoire VERSION 2.6.2

UNDERLYING CHANGES

  • Expanded functionality in combineBCR() and clonalCluster():
    • New metrics beyond normalized Levenshtein edit distances
    • Support for raw and normalized-based calculations

  • Added support for declaring chains = "IGL", "IGK", or "Light" to get all light chains in downstream quantification.

BUG FIXES

  • Fixed handling of multiple chains in combineBCR(), specifically in formatting CTstrict.
