  • Cufflinks "GffObj::getSpliced() error: improper genomic coordinate"

    Cufflinks is giving me this error:
    Code:
    $ cufflinks -p 4 -o analysis-multi/CaS1A/ -u -N -b Reference/AAA/mel_only.fa -G Reference/AAA/mel_only.gtf analysis-multi/CaS1A/assigned_dmel_rescued.bam 
    cufflinks: /lib64/libz.so.1: no version information available (required by cufflinks)
    You are using Cufflinks v2.0.2, which is the most recent release.

    I'm working on generating a minimal test set that reproduces the error, but in the mean time, does anyone have an idea what might be going on? The GTF file I'm using was generated directly from the FlyBase GFF file using:
    Code:
    gffread dmel-all-r5.46.gff -E -T -o- | awk '{print "dmel_"$0}' > mel_only.gtf
    so if there's a problem with something, it seems unlikely I'm the only one who's seen it.


    EDIT:

    Looks like there was something wrong with the fasta index for the fasta file. Deleting that and letting it get rebuilt fixed the error.

    Even I got this error
    GffObj::getSpliced() error: improper genomic coordinate 19628622 on chrY for NR_028083

    Same error (with the same coordinates) was there for two different samples, is there any problem with gtf file which was parsed with cufflinks or something else?

    Please help me out I am stuck.

        What should I do?
        Both files where downloaded from UCSC servers and the mm10.2bit was converted to Fasta using twoBitToFa

        Thank you!

          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...
