I have recently used AnnotationHub for annotation of mArray-Chip Results. But I have also found AnnotationDbi in Bioconductor. Looking into the vignettes, there seem to be no difference in the usage between both tools. What is the difference, and in which cases to use which tool?
AnnotationHub is a way to distribute different types of annotation resources. Some of the resources distributed by AnnotationHub are based on AnnotationDbi. Some are not.
I don't know what you mean when you say that there are no differences in the usage of the two; maybe you mean that once you have retrieved an AnnotationDbi resource from AnnnotationHub, the AnnotationDbi resource is used in the same way as an AnnotationDbi resource obtained from another source.
Can you be specific?

Ok, I have misunderstood so far, that AnnotationHub is using AnnotationDbi. What I meant is that both are using the same SQlite interfaces, commands, etc. and fullfill similar tasks? Sorry for my dilletante wording. Ah, I see you are one of the authors ... :-)
