Error in RenameGenesSeurat

Hi, thank you for the wonderful function!
I met the same problem as jenellewallace.

Hey JH,

thanks and sorry for the trouble. Very busy these days, try to address it next week.

Thanks for your help. I solved my problem using other methods. I'm writing my solution here in case anyone needs it in the future.

library(nichenetr)
library(Seurat)
exp_mtx <- as.matrix(Tcells1@assays$RNA@data)
con_df <- data.frame(mouse = rownames(exp_mtx),
                     hum_orig = convert_mouse_to_human_symbols(rownames(exp_mtx)),
                     stringsAsFactors = F)

con_df <- con_df[!is.na(con_df$hum_orig),,F]
exp_mtx <- exp_mtx[con_df$mouse,]
rownames(exp_mtx) <- con_df$hum_orig
human_SO <- CreateSeuratObject(counts = exp_mtx, meta.data = Tcells1@meta.data )
