Harmony issue

[emanuelavilla]

Hello Khushbu!
Thank you for all the videos and the knowledge you are sharing. You are helping me a lot!

I have a question about Harmony package. I was watching your video and saw a comment in which the person was asking if Harmony would work on different seurat objects, that he/she had merged together. I did the same, but got this error:

Harmony converged after 3 iterations
Error in UseMethod(generic = "Key", object = object) :
no applicable method for 'Key' applied to an object of class "character"

Do you know the error or did it happen to you the same?

I tried to search on the web, but I did not find anything useful for me.

Thanks a lot!
Emanuela
