Are there any packages available to convert "gene id to ensemble id". I am using "biomaRt" and "org.Hs.eg.db" but it does not able to convert "gene id to ensemble id".
I can convert "Gene Symbol to the ensemble" but with gene ID both packages show an error. eg. 'keys' must be a character vector
Genes name are in this format "A2BP1|54715", "A2LD1|87769", "A2ML1|144568". I am using only the integer part for conversion. As some genes have no name for example "?|155060" So I decided to stick with the conversion of the numbers.
