1. MULTI-seq is a hashing demultiplexing module from Seurat. I created the structure Seurat/Multi-seq because I intend to add another hashing demultiplexing module to the folder, which is also the property of Seurat (HTODemux), so both tools from the same library are located in the same place. Is that right?
2. These modules need many arguments to run its different functionalities, which I added in the nextflow.config file, any suggestion about this? especially, regarding the tests
3. also the code used to generate the plots for both tools is very very similar, any suggestion about it?

Hi @mari-ga . I'm back to having a little bit of spare time to look at nf-core things again, I'll try and take a proper look today.
