Currently I am trying to subset a portion of my scATAC-seq data to look at the DARs for inhibitory neuronal clusters. I have done the following:

sub_obj <- subset(object = obj_name, idents = "Inhibitory"), assuming that the cluster is named "inhibitory". Since there are several clusters identifying as such, I thought it would be easiest to extract those clusters this way.

I keep generating the error "Cannot find the following identities in the object".

Please help? Any other techniques to use here?
