Dear all,

What is the correct filter value for worm base genes like this:


I tried the following command, but it only gives NULL as value:

> library(biomaRt)
> mart <- useMart("ensembl")
> mart <-useDataset("celegans_gene_ensembl",mart)
> getBM(attributes=c("chromosome_name", "strand", "start_position", "end_position"), filters="wormpep_id",values="WBGene00022803", mart=mart)

Please kindly advice.
