Dear Friends,

I have a critical error in getting MA plot for agilent 244K chip data with plotPrintTipLoess command. Following are the steps which I followed to get the layout information from my GAL file.

> gal <- readGAL("014791_D_20080424.gal")
> RG$printer<-getLayout(gal)
> RG$printer
$ngrid.r
[1] 1

$ngrid.c
[1] 1

$nspot.r
[1] 912

$nspot.c
[1] 267

attr(,"class")
[1] "PrintLayout"

When I use following command to get MA plot with PrinTipLoess, It gives blank MA plot along with error information.

> plotPrintTipLoess(MA, array=1, layout=RG$printer)
Error in data.frame(y = object$M[, array], x = object$A[, array], gr = factor(gridc(layout)),  :
  arguments imply differing number of rows: 205700, 243504

I request community to help me to come out this error.

Thanking you in anticipation,

Prashantha
