hi,

can someone please explain to me, why is it, that I'm always getting the NULL-
value when I try to look fot the significance genes:
> data.out

s0 = 0

 Number of permutations: 100

 MEAN number of falsely called genes is computed.

 Delta: 10
 cutlow: -23.092
 cutup: 15.556
 p0: 0.321
 Significant Genes: 6
 Falsely Called Genes: 0
 FDR: 0


Genes called significant (using Delta = 10):

now, when I'm try to extract the information, I get:
> AE0625419.sum.out$row.sig.genes
NULL
> AE0625419.sum.out$mat.fdr
NULL
> AE0625419.sum.out$mat.sig
NULL

Can anyone please tell me, how can i reach these values?

THX
