Alakazam is part of the Immcantation analysis framework for Adaptive Immune Receptor Repertoire sequencing (AIRR-seq) and provides a set of tools to investigate lymphocyte receptor clonal lineages, diversity, gene usage, and other repertoire level properties, with a focus on high-throughput immunoglobulin (Ig) sequencing.
Alakazam serves five main purposes:
- Providing core functionality for other R packages in the Immcantation framework. This includes common tasks such as file I/O, basic DNA sequence manipulation, and interacting with V(D)J segment and gene annotations.
- Providing an R interface for interacting with the output of the pRESTO and Change-O tool suites.
- Performing lineage reconstruction on clonal populations of Ig sequences and analyzing the topology of the resultant lineage trees.
- Performing clonal abundance and diversity analysis on lymphocyte repertoires.
- Performing physicochemical property analyses of lymphocyte receptor sequences.
