Missing Column `annotation` in LRsig after merge cellchat and celltalk L-R pair

[wuy33]

Hi, I followed your instruction of updating cellchat DB by integrating celltalk L-R pairs, but after the run, I found column annotation is missing from the LRsig slot, which prohibited me to use some function like plotting bubble plot. I can manually add the column, but wonder whether this is a bug with using manually curated L-R database?
