I need some help with bioconductor.

 

I have run Poplar chip with the Affymetrix Platform and I want to analyze them with RMA using R. However, it seems since it is a new microarray chip that the Poplar cdf file is not available on bioconductor. I don't know if you are the best person to reach for that matter, if yes is it possible to add the Poplar cdf file in the library of bioconductor or if you are not the person in charge of that can you redirect me to the person in charge of those issues. 

 

This is the message I got from R.2.2.0

 

>>rma.set<-justRMA()

> 

> 

> Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered:

> 

> Specified environment does not contain Poplar

> 

> Library - package poplarcdf not installed

> 

> Data for package affy did not contain poplarcdf

> 

> Bioconductor - poplarcdf not available

 

 

Thank your for your help.
