Provides a suite of utilities that cover a range of complex analysis tasks for immunoglobulin (Ig) repertoire sequencing data. Change-O is a suite of utilities that (i) processes the output of V(D)J alignment tools, (ii) assigns clonal clusters to Ig sequences and (iii) reconstructs germline sequences. It also offers applications to import data from the frequently used IMGT/HighV-QUEST tool and a set of utilities to perform basic database operations, such as sorting, filtering and modifying annotations.
A universal framework that processes big immunome data from raw sequences to quantitated clonotypes. MiXCR efficiently handles paired- and single-end reads, considers sequence quality, corrects PCR errors and identifies germline hypermutations. The software supports both partial- and full-length profiling and employs all available RNA or DNA information, including sequences upstream of V and downstream of J gene segments.
Utilizes re-alignment to identify V(D)J genes and alleles after common local alignment. A methodology is developed to correct the PCR and sequencing errors, and to minimize the PCR bias among various rearranged sequences with different V and J gene families. IMonitor provides general adaptation for sequences from all receptor chains of different species and outputs useful statistics and visualizations. Usefulness of IMonitor was demonstrated on minimal residual disease detection of patients with B-cell Acute Lymphoblastic leukemia.
A software package that significantly improves the completeness and accuracy of TCR/IG profiling from deep sequence data and includes procedures to identify novel alleles of gene segments. The alignment step in LymAnalyzer, which is based on a fast-tag-searching algorithm, results in rapid identification of VDJ gene segments, with significantly improved accuracy and completeness compared to existing tools applied to TCR data. In addition, LymAnalyzer can be applied to IG sequences, includes an integrated single nucleotide polymorphism (SNP) calling algorithm that identifies novel alleles of the VDJ gene segments and produces lineage mutation trees to represent the affinity maturation process of the IGs. On real and simulated data sets LymAnalyzer produces highly accurate and complete results. Although, to date we have applied it to TCR/IG data from human and mouse, it can be applied to data from any species for which an appropriate database of reference genes is available.
Offers a platform for comprehensive analyses of B cell receptor repertoires, using IMGT/HighV-QUEST formatted data. bcRep is a R package that combines techniques for studying clones and also the total set of input sequences or subsets of sequences. This program allows users to filter these sequences for their functionality or junction frame usage, and clones also for their size.
Processes raw immune sequence reads from any source and learns unbiased statistics of recombination and somatic hypermutations. IGoR is a flexible computational method that outputs a whole list of potential recombination and hypermutation scenarios, with their corresponding likelihoods. It learns a context-dependent hypermutation model to identify hotspots, which allows for a comprehensive analysis of the mutational landscape of B cells receptor (BCR).
A flexible toolkit for the processing and analysis of antigen receptor repertoire sequencing data at single-cell level. The software combines bioinformatics tools for immunoglobulin sequence annotation with a relational database, where raw data and analysis results are stored and linked. sciReptor supports attribution of additional data categories such as cell surface marker expression or immunological metadata. Furthermore, it comprises a quality control module as well as basic repertoire visualization tools.
