This vignette inside AnnotationHub gives you a quick tour on how to access these files  via the Hub with some examples.

Please let us know if you'd like any other files to be added to the Hub from the same project or another.

Thanks and Regards,

Hi Sonali, are there any plans to add access to the raw data (ie consolidated and unconsolidated tagAlign files) through AnnotationHub? As far as I can tell, this info is not indexed in a publicly accessible way and the easiest method currently is just to parse the file names from the web server HTML. Also, does AnnotationHub provide any methods to download files to disk rather than straight into R? Obviously for large BAM-type files working in memory is not always an option.

cache(hub["AH12345"]) retrieves the resource(s) to local disk (if necessary) and returns the path. Mostly large files are not read in to R, but returned in a format that can be queried for relevant information (as with the fasta file vignette example).

Dear Sonali,

I just posted a question regarding some Roadmap files: AnnotationHub: confusing pValue/qValue for (some) Roadmap records
