[BioC] siggenes R-fold question

[wxu at msi.umn.edu]

 Hello,

 I have the following question which I could not find the answer from the
 FAQ. What does the R.fold mean in the siggenes sam? Why does it give such
 a big number such as 2.68E+74, or small number such as 1.18E-25? It is
 different from the fold I got from the Excel SAM that seems the real fold
 change.

 Thanks in advance,

 Wayne
