AbSim (version 0.2.6)

Time Resolved Simulations of Antibody Repertoires

Description

Simulation methods for the evolution of antibody repertoires. The heavy and light chain variable region of both human and C57BL/6 mice can be simulated in a time-dependent fashion. Both single lineages using one set of V-, D-, and J-genes or full repertoires can be simulated. The algorithm begins with an initial V-D-J recombination event, starting the first phylogenetic tree. Upon completion, the main loop of the algorithm begins, with each iteration representing one simulated time step. Various mutation events are possible at each time step, contributing to a diverse final repertoire.

singleLineage

Antibody lineage simulations using only one set of V(D)J germline genes. The main difference between this function and the fullRepertoire function is that there can be multiple VDJ recombination events within one tree. Each VDJ recombination event in the singleLineage function is a branching event within the existing tree, whereas the VDJ recombination events in the fullRepertoire function start a new tree.

fullRepertoire

Simulates full heavy chain antibody repertoires for either human or mice.
repertoireFastas

Converts AbSim's output sequences and names into fasta file format. Each tree within the repertire will be stored in an individual fasta file. Utilizes sink() and cloneAllConnections() from R base
