STARsolo for 10X Chromium fastqs with HTO libraries #10

Closed OluwayioseOA closed 1 week ago

OluwayioseOA commented 2 months ago

Hi Alex, I have some 10X chromium fastq libraries (R1/R2), each with HTO libraries (R1/R2) for sample demultiplexing. I successfully ran "cellranger count" but we wanted to replicate this using STARsolo. However, I did not find the option to include the HTO libraries in my line of code (please see below). Please would you have any suggestion for me on this?

Hi,

Sorry, totally forgot to answer you! There is no option to process HTO or ADT datasets in STARsolo, unfortunately. However you always can process the gene expression part (GEX) of your experiment separately (since HTO usually is done together with GEX). That would be normal STARsolo, run as usual. After this you can take the results of demultiplexing (i.e. barcode to sample table) and use it on your STARsolo results.
