[vertesy]

Hi Song, sure, happy to,

1. Seurat
2. Seurat.utils

Hi ,
I changed my code like this:

ids=select(org.Mm.eg.db,keys = rownames(sc_object),
             columns = c('ENSEMBL','SYMBOL'),
             keytype = 'ENSEMBL')
  head(ids)
  dim(ids) # 
  ids=na.omit(ids)
  dim(ids) 
  length(unique(ids$SYMBOL)) # 
  ids=ids[!duplicated(ids$SYMBOL),]
  ids=ids[!duplicated(ids$ENSEMBL),]
  pos=match(ids$ENSEMBL,rownames(sc_object) )
  sc_object=sc_object[pos,]
  
  sc_object =RenameGenesSeurat(obj = sc_object,
                         newnames = ids$SYMBOL)

This time it do well !

THANKS,
SONG

Hi vertesy,
Now I have an another problem that in the org.Mm.eg.db, I did not have like "mt-" mitochondrial genes, how can I filter it when the name is not standard for PercentageFeatureSet(sc_object, pattern = "^mt-") function that in order to QC.

THANKS，
SONG

I am sorry but this goes beyond what I can support.
PercentageFeatureSet is anyways Seurat, not this package

Hi vertesy:
Thank you very much! I know why my first method is not work, because here is a empty symbol gene name to match the ensembl id, but the org.Mm.eg.db database matches it, so the second one work well.
I can fix them together to solve the problem.

THANKS，
SONG
