How to use the "ECM-Receptor" and "Cell-Cell Contact" in the database?

Hi @sqjin, I just wonder how to use the "ECM-Receptor" and "Cell-Cell Contact" annotation in the package? Could you give a quick example of these two part?
Thanks!

Hi @guokai8, you can use all the interactions by CellChatDB.use = CellChatDB.mouse , and only ECM-Receptor interactions by CellChatDB.use <- subsetDB(CellChatDB.mouse, search = "ECM-Receptor", key = "annotation"). Our tutorial also shows the example for using Secreted Signaling.
