For example, for 10x VDJ data:

> mixcr exportQc plots 10x-data.clns barcodesFiltering.pdf 

The upper plot shows reads per UMI distribution and cut-off threshold used to filter erroneous UMIs. The second plot shows UMI per cell barcode distribution and cut-off threshold used to filter erroneous cell barcodes.
