  • NOT NULL constraint failed: genes.gene_id

    Hi,

    I am using readCufflinks but got the following error:

    -------------------------
    > cuff_data <- readCufflinks('EFt_bwa',gtfFile="transcripts.gtf",genome="gi|157779983|gb|EF999921.1|",rebuild=T)

    Error in sqliteSendQuery(con, statement, bind.data) :
    rsqlite_query_send: could not execute: NOT NULL constraint failed: genes.gene_id
    -----------------------

    The file transcripts.gtf (see below) was generated by Cufflinks "cufflinks -p 8 -G /rsgrps/fgoodrum/Referance/ref_annotation.gff3 ../cleant6_bwa_sortedc.bam" , where the bam file was from the POOLED total reads file mapping to the reference, and transcripts.gtf was used for cuffdiff.
    -------------------------------
    [Victoria@service0 cuffdiff]$ head -3 transcripts.gtf

    gi|157779983|gb|EF999921.1| Cufflinks transcript 331 1008 1000 - . gene_id ""; transcript_id "US7"; FPKM "230.5778142799"; frac "1.000000"; conf_lo "216.465711"; conf_hi "244.689918"; cov "554.839664";

    --------------------

    For the cuffdiff results, it seems only isoform_exp.diff has records but no records for others (genes, cds etc).

    Thank you!
    Victoria

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

    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...
