Hi! Trying to follow the Muon tutorial, I get stuck on: pt.pp.dsb(mdata, raw=mdata\_raw, empty\_droplets=droplets)

NameError: name ‘droplets’ is not defined

Can anyone help?

Hey @LivR,

In the [original CITE-seq tutorial](https://muon-tutorials.readthedocs.io/en/latest/cite-seq/1-CITE-seq-PBMC-5k.html), the interface of this function is demonstrated to require `empty_counts_range` provided using the `log10umi` scale.  
We might change this in future versions to enable providing exact barcodes (which would be more flexible I believe) but that’s currently the interface. So there’s no argument `empty_droplets` at the moment. 😃
