CummeRbund: populate db

[dGho]

I am a complete nube when it comes to CummeRbund and SQL, so I apologize for this very simple question. I read the following in the CummeRbund manual:


populate the 'cuffData.db' database backend, and return the CuffSet pointer object, you can do the following.

> library(cummeRbund)
> cuff<-readCufflinks()
> cuff

CuffSet instance with:
3 samples
400 genes
1203 isoforms
662 TSS
906 CDS
1062 promoters
1986 splicing
990 relCDS

sorry, I am embarrassed asking this question but what exactly is going on in the above example. If I do this, does this mean my db is "populated"?

This basically means cummeRbund will read in the cuffdiff output files and write the information in a database, that remains in your working directory and can be reloaded fast. Then cummeRbund works on that database.

sorry, it was not the most intelligent question.

Thank you very much sBeier
