MIGEC
|
Read assignment by barcode (de-multiplexing) and consensus assembling based on UMIs using the open-source tool MIGEC.
|
I: NGS files in compressed or non-compressed FASTQ file format O: assembled reads in FASTQ file format
|
|
MiXCR
|
Execution of MiXCR commands for clonotype identification and quantification for receiving nucleotide and AA sequences of the CDR3 region and V(D)J gene segments.
|
I: files in compressed or non-compressed FASTQ file format O: immune repertoire profiling measures (e.g., V(D)J gene segments, CDRs etc.) in text file format
|
|
ContaminationAnalysis
|
Calculates shared UMIs and V(D)J hits of multiple samples for cross-sample contamination analysis.
|
I: MiXCR output, MIGEC output or non-compressed FASTQ files containing the UMI sequence in the read ID O: cleaned FASTQ files
|
|
FACSCorrection
|
Cell subset disambiguation of clonotypes from cells separated using FACS or magnetic sorting (e.g., CD4+ and CD8+) and elimination of clonotypes within a twofold change range.
|
I: filename of pairs for analysis (pairs.txt) and MiXCR output O: cleaned files in MiXCR text file format
|
|
VDJtools
|
Executes methods of the open-source tool VDJtools (convert and calculate diversity indices) for diversity stats visualization later-on.
|
I: MiXCR output O: diversity indices for all samples
|
|
Bowtie
|
Analyze undetermined reads from sequencing run and from MIGEC assignment using the open-source tool Bowtie2 for non-assignable read composition analysis.
|
I: file path to the undetermined files in compressed or non-compressed FASTQ file format and to MIGEC undef-m output file, and path to Bowtie2 library O: mapping information is collected in SAM file format
|
|
EvaluateUndetermined
|
If undetermined read analysis using Bowtie2 has been performed, evaluation and visualization of the results is done.
|
I: the Bowtie2 output in SAM file format O: read counts for each category (see Undetermined Read Processing and Analysis)
|
|
ClonalityAnalysis
|
Clonotype and CDR3 sequence length analysis and visualization is performed.
|
I: MiXCR output O: CDR3 AA length distribution and clonotype counts
|
|
DiversityAnalysis
|
Diversity curves are calculated and visualized as well as the diversity indices calculated using VDJtools.
|
I: MiXCR output and VDJtools output O: diversity curves and diversity measures
|
|
OverlapAnalysis
|
Shared clonotype analysis and visualization.
|
I: MiXCR output O: shared clonotype overlaps (heatmap and LM plots)
|
|
SimilarityAnalysis
|
Hierarchical clustering of all samples is performed and visualized.
|
I: MiXCR output O: hierarchical clustering information
|
|
VDJAnalysis
|
Calculation of V and J gene segment pairings and visualization using Chord diagrams.
|
I: MiXCR output O: chord diagrams
