[BioC] combineAffyBatch problem

[Catherine Dumur]

Dear Wolfgang and Bioconductor people,

I am using the combineAffyBatch function from the matchprobes package 
regularly now, and I am very pleased with its performance.

However, I was wondering if you can help me with the following:

I understand that every time I run the function, a new .CDF object is 
created and this takes a considerable amount of time. I was wondering if 
we can re-use an existing "newcdf" object when performing new analysis 
where the same two types of arrays are used. In other words, since I am 
always combining the same 2 types Affy chips, the newcdf object should 
be the same. If I use that object from previous sessions, I shouldn't be 
creating a new one every time.

I would greatly appreciate it if you could tell me if that is feasible, 
and if it is, how can I  do it.

Thank you very much for your attention to this issue.


Cathy
