Hi Weiwei,

I cannot tell you very much about the etymology of the name since it was 
named well before I got here, but I do think that "rgug4130a.db" is the 
package you want.  If you still have doubts you should be able to check 
the probes in the package against the probes that are on your platform 
to verify that this is the one you want.

As for your other question, the package that you want to use is always 
the one that ends with ".db".  These are the newer format for these 
packages, and the older style will not be around much longer.

You can find out more information by reading the vignettes at this website:
