DriverMap Adaptive Immune Receptor (AIR) DNA TCR-BCR Profiling
Easy-to-run, single-day assay that uses multiplex PCR-NGS technology to profile T-cell receptor (TCR) or B-cell receptor (BCR) repertoire present in human DNA. The DriverMap AIR DNA assay measures the frequency of CDR3 clonotypes to quantify the clonal frequency of T and B cells.
Bellow you can see the structure of cDNA library.
The data for this tutorial consists of one sample prepared according to the manufacturer's protocol.
All data may be downloaded using the script bellow.
Use aria2c for efficient download of the full dataset with the proper filenames:
mkdir -p raw
aria2c -c -s 16 -x 16 -k 1M -j 8 -i download-list.txt
ftp://ftp.sra.ebi.ac.uk/vol1/fastq/SRR264/031/SRR26446931/SRR26446931_1.fastq.gz

ftp://ftp.sra.ebi.ac.uk/vol1/fastq/SRR264/031/SRR26446931/SRR26446931_2.fastq.gz
out=raw/Sample1_R2.fastq.gz
Upstream analysis
MiXCR has a dedicated preset for this protocol, thus analysing the data is as easy as:
mixcr analyze cellecta-human-dna-xcr-umi-drivermap-air \
raw/Sample1_R1.fastq.gz \
raw/Sample1_R2.fastq.gz \
results/Sample1
Running the command above will generate the following files:
> ls result/
# human-readable reports
Sample1.align.report.txt
Sample1.align.report.json
Sample1.refine.report.txt
Sample1.refine.report.json
Sample1.assemble.report.txt
Sample1.assemle.report.json
# raw alignments (highly compressed binary file)
Sample1.vdjca
#Alignments with corrected barcode after ```mixcr refineTagsAndSort```
Sample1.refined.vdjca
# TCR and BCR CDR3 clonotypes (highly compressed binary file)
Sample1.clns
# TCR and BCR CDR3 clonotypes exported in tab-delimited txt
Sample1.clones_IGH.tsv
Sample1.clones_IGK.tsv
Sample1.clones_IGL.tsv
Sample1.clones_TRAD.tsv
Sample1.clones_TRB.tsv
While .clns
file holds all data and is used for downstream analysis using mixcr postanalisis
, the output .txt
clonotype table will contain exhaustive information about each clonotype as well:

Quality control
Now let's look at the QC plots. That can be easily done using mixcr exportQc
function.
First we will look at the alignment report:
mixcr exportQc align \
Sample1.clns \
figs/alignQc.pdf
From this plot we can tell that all samples have high alignment rate and nearly 90% of all reads from each sample have been successfully aligned to the reference sequences and CDR3 has been established.
Now we can check chains distribution plot:
mixcr exportQc chainUsage \
results/Sample1.clns \
figs/chainUsage.pdf
Finally, we can take a look at the reads per UMI distribution.
mixcr exportQc tags \
results/Sample1.clns \
figs/tags.pdf
Reports
Finally, MiXCR provides a very convenient way to look at the reports generated at ech step. Every .vdjca
, .clns
and .clna
file holds all the reports for every MiXCR function that has been applied to this sample. E.g. in our case .clns
file contains reports for mixcr align
and mixcr assemble
. To output this report use mixcr exportReports
as shown bellow. Note --json
parameter will output a JSON-formatted report.
mixcr exportReports \
results/Sample1.clns \
results/Sample1.report.txt
mixcr exportReports \
--json \
results/Sample1.clns \
results/Sample1.report.json
