[BioC] Mas5, normalization method, error

Dear Yisong

When I run the following code,

   library("affy")
   raw.data<-ReadAffy("E-MEXP-1478-raw-cel-1594215448.cel")
   mas5.data<-mas5(raw.data);

I get

background correction: mas
PM/MM correction : mas
expression values: mas
background correcting...Errore in getCdfInfo(object) :
   Could not obtain CDF environment, problems encountered:
Specified environment does not contain CINT06a520380F
Library - package cint06a520380fcdf not installed
Bioconductor - cint06a520380fcdf not available

Can you also provide the CDF package for your array? It might be worth 
getting in touch with the person who designed the array to make sure 
MAS5 is appropriate for it (e.g. does it have probesets, and mismatch 
probes?)

PS Luckily, the EBIs http servers have no problem and your cel file used 
in the above example is here:
