Hi All, I’m trying to run

cellranger multi

on some multiplexed single-cell data, using the

--cellranger_multi_barcodes

option. But I get this error:

We detected multiple probe barcodes in: Sample Lib_Flex_Multiplexing_INF-01 in "fastq_all/gex"
Singleplex Flex chemistry is invalid with >1 probe barcode. If this is a multiplex Flex library please include a [samples] section defining the inputs.
The following top probe barcodes were observed: BC001, BC002, BC003.

It looks like the

[samples]

section isn’t being created in my

cellranger_multi_config.csv

. Any tips on how to fix this so it works with multiple probe barcodes?

Hi, Sorry for the delay here! Do you have examples of the CSVs you used and maybe the cellranger task log?
