    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.

            Current Approaches to Protein Sequencing
            by seqadmin


            Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

            Strategies for Sequencing Challenging Samples
            by seqadmin


            Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
