How to find UMI counts from cell ranger VDJ output

Question

[Kevin]

I ran cell ranger multi with VDJ and cell surface samples and the results look good. I have not been able to find info on UMI counts for IgH, IgL, or IgK and was wondering if there is a specific file I should be looking in? Would they have needed to be included in the feature barcode csv as part of cell rangers input?

hi, I would also suggest using MiXCR for 10x vdj data analysis. There is a single line command for that:

mixcr analyze 10x-vdj-bcr \
 --species hsa \
 sample_R1.fastq.gz \
 sample_R2.fastq.gz \
 sample_result

As the result you will get several files, the tsv file will have all the info for every clone (cell barcode, umi barcode, cdr3 sequence, etc.)
