Hello, 
  I encounter an error while reading in gpr files with read.maimages. My codes are:

f <- function(x) as.numeric(x$Flags > -50.5)
RG <- read.maimages(targets, source="genepix", wt.fun=f)

Error message is:
Read GSM237424.gpr 
Read GSM237425.gpr 
Read GSM237426.gpr 
Read GSM237427.gpr 
Error in RG[[a]][, i] <- obj[, columns[[a]]] : 
  number of items to replace is not a multiple of replacement length

I believe this is due to a different gpr format among some of the files. The first 4 that were read successfully are of "GenePix Result 3" type, and the next one which failed is of "GenePix Results 2" type. I checked the data, and found these versions differ in # of rows and columns. 
 
Does this mean I am unable to use Bioconductor to read + process gGenePix pr files that are of different output versions?

Thanks!
Casper
