[BioC] SimpeAffy: how to get/generate qcdef file?

[Renaud Gaujoux]

Hi list,

how can one generate the qcdef file required by SimpleAffy in the case 
of a sugarcane Affymetrix array.
I installed and loaded the sugarcanecdf package. Since it is in the 
Bioconductor repository I thought the qcdef file would come together.
Is there a function that generate the qcdef file automatically from the 
cdf file? Ohterwise how does one know what to put in the the qcdef file?

Thank you,
Renaud.
