Hi everybody!

I am trying to read several .cel files from Affymetrix Exon Arrays with the R program. I have loaded the affy, affyio, oligo and packages but when I write the command read.affybatch(dir()[1]) it does not work and the following message appears:

AffyBatch object
size of arrays=2560x2560 features (17 kb)
cdf=HuEx-1_0-st-v2 (??? affyids)
number of samples=1
Error in getCdfInfo(object) :
Could not obtain CDF environment, problems encountered:
Specified environment does not contain HuEx-1_0-st-v2
Library - package huex10stv2cdf not installed
Bioconductor - huex10stv2cdf not available
In addition: Warning messages:
1: In read.affybatch(dir()[1]) :
Incompatible phenoData object. Created a new one.
2: missing cdf environment! in show(AffyBatch)

I have looked for the huex10stv2cdf package through the internet but I cannot find it.

Moreover if I write read.celfile(dir()[1]), a huge list appears without any information even when I ask for it.

Could anyone help me, please? Any advice would be really welcome.

Moderators can you please remove the wrong tag and modify the query? @OP please try to modify the query so that others can read it properly and also the tag for tutorial is not errors centric rather informative resource. Please change it.
