  • CummeRbund error

    Hi,
    I'm stuck in this cummeRbund error:

    library(cummeRbund)
    cuff_data <- readCufflinks('diff_out')
    Creating database diff_out/cuffData.db
    Reading diff_out/genes.fpkm_tracking
    Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
    line 1 did not have 33 elements

    If someone can help...
    Thanks

    Hi,

    I am having the same error:

    cuff_data <- readCufflinks ('diff_out')
    Creating database diff_out/cuffData.db
    Reading diff_out/genes.fpkm_tracking
    Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
    line 1 did not have 25 elements


    Were you able to resolve this problem?

    Thanks.

      I look all the files searching the problem...the problem was in the GFF3 (or GTF) file. The '#' character appeared in some gene names.
      Probably your annotation file have some character that the R don't recognize.

        Thanks. I deleted all the '#' characters and received some progress but another error.

        It may just be the same problem but with the gene_exp.diff file this time.
        Thanks again and I appreciate your help!

          I'm glad that I can help.
          I ran all the TopHat and cufflinks pipeline with the GFF3 corrected to avoid errors and it worked well for me.

            Hi
            I have similar problem while loading database in commeRbund

            > library("cummeRbund")
            > cuff_data<-readCufflinks('cuffdiff_output_sample-ATvsBC')
            Creating database /cuffdiff_output_sample-ATvsBC/cuffData.db
            Reading Run Info File cuffdiff_output_sample-ATvsBC/run.info
            Writing runInfo Table
            Reading Read Group Info cuffdiff_output_sample-ATvsBC/read_groups.info
            Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
            line 1 did not have 7 elements

            Then I try

            > cuff_data
            CuffSet instance with:
            0 samples
            0 genes
            0 isoforms
            0 TSS
            0 CDS
            0 promoters
            0 splicing
            0 relCDS

            The cuffData.db file is only 70kb, so I assume there are some error in loading db.
            Any help will be highly appreciated.

                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...
