Cell barcode IDs for processed ATAC SummarizedExperiment objects

[andrewjkwok]

Hi,

Many thanks for the repository of code and data. I was hoping to use some of the healthy scATAC datasets, but after downloading the healthy hematopoiesis scATAC cell x peak SummarizedExperiment object, I found that the cell names (column names) are all in the form BMM_R1_15, BMM_R1_16... etc.

However, the fragment files when I download them have the 10X cell barcodes. Is there a way I can match the barcodes back to the processed SummarizedExperiment objects? I've looked in the various metadata slots for the SummarizedExperiment object but can't seem to find anything.

Many thanks in advance.
