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.)

You can read more on it here: https://docs.milaboratories.com/mixcr/reference/overview-built-in-presets/#10xgenomics
