    I was wondering if anyone else gets the error:

    Error in validObject(.Object) :
    invalid class "countData" object: invalid object for slot "data" in class "countData": got class "data.frame", should be or extend class "matrix"

    when trying to import data into baySeq. I am using a simlar spreadsheet which worked for DESeq, DEGseq and edgeR but it doesnt work for baySeq. I have tried playing around with removing the labels etc but to no avail.

    any help would be greatly appreciated

    The problem appears to be that the 'raw.data' object is of class 'data.frame' rather than class 'matrix'. If you try the following:

    > raw.data <- as.matrix(raw.data)

    before the command

    > CD <- new("countData", data = raw.data, replicates = replicates,
    + libsizes = libsizes, groups = groups)

    then this should succeed.

      Also, if anyone else is using the programme what number of iterations and bootstraps are you using for your data set?

        Can anyone please let me know why I am encountering this problem in baySeq. Thank you.

          I installed the latest version 1.8.3 and followed the manual, got the following error:

          replicates <- c("simA", "simA", "simA", "simA", "simA", "simB", "simB", "simB", "simB","simB")

          Error in validObject(.Object) :
          invalid class "countData" object: invalid object for slot "replicates" in class "countData": got class "character", should be or extend class "numeric"

          But they are characters in the manual as well.

          Anyone experienced it? Tia.
