Hi

I have multiple pair files from a Nimblegen methylation array that I have converted to XYS files. I am trying to feed them into pdInfobuilder using the script below, but it crashes out with the following error:

Error in validObject(.Object) :
  invalid class “ScalarCharacter” object: ScalarCharacter must have length one

Does this mean that pdInfobuilder can only take one file at a time? I thought that as the file was being read into an array it could analyse multiple files

Thanks

Andrew


library(pdInfoBuilder)
baseDir <- "/mnt/cdrive/Nimblegen/methylationpercentages"
ndf <- list.files(baseDir, pattern = ".ndf",full.names = TRUE)
xys <- list.files(baseDir, pattern = ".xys",full.names = TRUE)
pos <- list.files(baseDir, pattern = ".pos",full.names = TRUE)
seed <- new("NgsTilingPDInfoPkgSeed",ndfFile = ndf, xysFile = xys, posFile = pos, author = "Andrew Beggs", email = "a.beggs@bham.ac.uk", biocViews = "AnnotationData",genomebuild = "HG 18", organism = "Human", species = "Homo Sapiens", url = "http://www.biostat.jhsph.edu/~bcarvalh")
