scoperR Documentation

The SCOPer package


scoper is a member of the Immcantation framework and provides computational approaches for the identification of B cell clones from adaptive immune receptor repertoire sequencing (AIRR-Seq) datasets. It includes methods for assigning clonal identifiers using sequence identity, hierarchical clustering, and spectral clustering.

Clonal clustering

  • identicalClones: Clonal assignment using sequence identity partitioning.

  • hierarchicalClones: Hierarchical clustering approach to clonal assignment.

  • spectralClones: Spectral clustering approach to clonal assignment.


  • plotCloneSummary: Visualize inter- and intra-clone distances.
