How to use user defined ligand-receptor datasets

[wwn7268]

Hi CellphoneDB team,

I want to infer cell-cell communication with my owe database. I try to use the code below.

cellphonedb database generate --user-interactions your_custom_interaction_file.csv --user-interactions-only

So what kind of csv file should I input? Could you show me an example of this csv file. Thank you very mauch!

Best

Hi @wwn7268,

You use the original as example:
https://github.com/Teichlab/cellphonedb-data/tree/master/data

Here you can check the mandatory columns and the process.

Best!
