Dear list,

I am trying to translate mouse Entrez ids  into human orthologous Entrez ids using inparanoid, and I am getting an error:

>  humanEGs<-inpIDMapper(tmp, srcSpecies="MUSMU", destSpecies="HOMSA", srcIDType="EG", destIDType="EG")

Error in names(destIDs) = dnames : attempt to set an attribute on NULL

> head(tmp)
[1] "269378" "211660" "211660" "211660" "98711"  "669171"
(looks all right)

I would be grateful if someone could indicate what I am doing wrong.
Probably I missed something important about the status of INPARANOID database and AnnotationDBI?

In the same time, if I am doing this via BiomaRt:
tm2<-getLDS(attributes ="entrezgene",filters = "entrezgene", values = tmp, mart = mouse, attributesL = c("affy_hg_u133a","entrezgene"), martL = human)

I get  results and at the first glance it looks consistent. But I would prefer to use inparanoid scheme for matching orthologs...
I would appreciate your help.

Best regards
Galina
