Dear Pedro,

I am using AgiMicroRna 1.0.0 to process my agilent miRNA
microarray data. Agilent Feature Extraction Software v10.7 was
used to extract the features. I got segfault when I do rmaMicroRna:

 

> dd.rma=rmaMicroRna(dd.micro,

+  normalize=TRUE,

+  background=TRUE)

 

 *** caught segfault ***

address 0x10cd6000,
cause 'memory not mapped'

 

However, this
problem is gone when I do rmaMicroRna on a subset of my dd.micro: 

> dd.rma=rmaMicroRna(dd.micro[,13:16],

+  normalize=TRUE,

+  background=TRUE)

 

I have check my dd.micro
data, everything is fine. In other words, rmaMicroRna only works when I apply
it to a smaller dataset. BTW, I am using a 64 bit version of R on linux
machine. Therefore, memory limit shouldn’t be an issue here. Could you look at
this issue? Thanks a lot!
