    Help with DESeq please

    Hello everyone
    I am new in the use of DESeq and I have problems for obtain Diferencial Expression of an Output of EDGE-Pro.
    In R, I followed the steps on this page:

    https://wikis.utexas.edu/display/bio...ssion+analysis

    In where are the next steps:

    login1$ R
    ...
    > library("DESeq")
    > counts = read.delim("gene_counts.tab", header=F, row.names=1)
    > head(counts)
    > colnames(counts) = c("wt1", "mut1", "wt2", "mut2")
    > head(counts)
    > my.design <- data.frame(row.names = colnames( counts ),condition = c( "wt", "mut", "wt", "mut"), libType = c( "single-end", "single-end", "single-end", "single-end" ))
    > conds <- factor(my.design$condition)
    > cds <- newCountDataSet( counts, conds )

    BUT, in this point, I have the next error:

    Error en round(countData) : non-numeric argument to mathematical function

    Someone can help me? please

    My file is the next (the firsts five lines):

    gene 571A.rpkm_0 571B.rpkm_0 571C.rpkm_0 571D.rpkm_0
    geneA 406 609 423 477
    geneB 67 117 76 64
    geneC 21134 18099 14720 14153
    geneD 810 857 725 691

    Each 571 is one condition, without replicates.

    Is counts formatted correctly, does
    Code:
    head(counts)
    look like you'd expect?

    Is there a reason you are not using DESeq2? In DESeq2 you'd use DESeqDataSetFromMatrix instead of newCountDataSet:

    Code:
    dds <- DESeqDataSetFromMatrix(countData = counts,
                                  colData = my.design,
                                  design = <formula>)
    You should follow the PDFs available here:

      The table looks as expected, but I will try of use DESeq2. However, still I can not solve this problem in DESEQ.

        Check to make sure your sample and gene names do not include spaces. If they do, it will throw off the column numbers.

          Hi
          Finally I used DEseq2 and I could get what I expected. Thanks for all and greetings !!

            Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
            by SEQadmin2


            Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

            Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
            by SEQadmin2



            Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

            Cancer Drug Resistance: The Lingering Barrier to Rising Survival
            by SEQadmin2



            Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

            There is no single reason why many patients don’t respond to treatment as expected. Cancer is...
