[BioC] maSigPro and "subscript out of bounds"

[andrea.grilli at ior.it]

Hi all,
I'm performing time series experiment with maSigPro package. When I  
compute regression fit to find significant genes with "p.vector"  
function, I receive this output:
Error: subscript out of bounds

Here you can find a resume of my script:
library("maSigPro")
parameters <- as.matrix(read.table("./Parameters.txt", header = TRUE))  
# design object
design <- make.design.matrix (parameters, degree = 3)
Data <- read.table("./Data_RMAnorm.txt") # expression object
fit <- p.vector(Data, design, Q = 0.05, MT.adjust = "BH", min.obs = 20)
> Error: subscript out of bounds

It looks like no right dimension of either design or array objects,  
but both input files look ok for me.

Data table comes from previous write.table after import of .CEL files  
with ReadAffy and RMA normalization (from affymetryx platform  
HG-U133_Plus_2).
R version is 2.11.1, instead maSigPro is 1.24.1.

I focus that I'm new to Bioconductor, so I hope problem is clear....
Any idea about possible solutions??

Thanks in advance,
Andrea
