FAQs
General
How to install BRB-ArrayTools if you have 64-bit MS-Office?
There is no difference in terms of the installation.
If installation, I can not find the BRB-ArrayTools in Windows > Start > All Programs.
Check EXCEL.
Can I upgrade R?
Better not.
Can I install multiple versions of R?
Yes.
Rserve
Since version 4.3.0, BRB-ArrayTools started to use Rserve as a media for the communication between R and Excel. When Rserve is required, an R window will be pop up. This R window has a blue icon on the Windows' taskbar. If you accidentally close it, it will be automatically popped up when it is needed.
See my Rserve wiki page.
Analysis

Ask your local help desk.
For affy cel files, GCRMA has a memory problem and MAS5 is way too slow
It is a known problem. BRB-ArrayTools uses justGCRMA() function in 'gcrma' package for GCRMA option and justMAS() function in 'simpleaffy' package for MAS5 option.
