Dear All, I think the problem is, that specified annonated cdf environment should be established, such as rmHu01Aa520485.CDF, when we use the bioconductor to preprocessing microRNA microarray datasets. It seems to be my nightmare to creat the cdf file then create in R project. So, I need a CDF-file of this library file. Best Regards! Bai [[alternative HTML version deleted]]

Hi Bai, That doesn't look like a commercial chip. We supply cdf packages for chips that Affy makes available on their website, but are unable to do so for chips that are not downloadable. We do make the makecdfenv package available, with an explicit vignette to show people how to make a cdf package. I would recommend reading the vignette and follow those instructions.
