I am trying to convert a list of different species Ensembl Gene IDs to NCBI Gene IDs. I found out that, given a list of same species Ensembl Gene Ids. We can obtain the NCBI Gene IDs through biomaRt Converting gene names.
However, I am not sure to obtain the list of NCBI Gene IDs, given the large list of Ensembl Gene IDs belonging to different species.
ENSAPLG00000002137 ENSATEG00000009947 ENSACAG00000001379
Can anyone suggest if there is any approach to automatically retrieve the NCBI gene IDs?
