  • Cuffmerge Issue

    Hi,

    Can somebody please help/advise with this cuffmerge issue?

    I am having an issue with merging the cufflinks transcripts.gtf file with cuffmerge. I have two files that I need to merge, the command is as follows

    cuffmerge -g genes.gtf -s /mnt/yabba/yoda_backup/var/data/hg19.fa assemblies.txt

    The output file merged_asm is completely empty! I have run this now a number of times and still no output.

    I am not receiving any errors and simulation finishes after 5 secs, as per below.

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

    [Thu Jan 10 13:00:48 2013] Preparing output location ./merged_asm/
    [Thu Jan 10 13:00:53 2013] Converting GTF files to SAM
    [stephen@biosc-sub2-169]$

    I chaged the input variables and it kept returning errors. However, I created a blank .txt doc called genes.gtf and ran the command, this produced the same result as above, no errors and no output.

    I believe the genes.gtf file is not being read correctly any maybe in a different format to the cufflinks out put.

    The Tophat index that was used to map the reads H. sapiens, UCSC hg19 downloaded from http://bowtie-bio.sourceforge.net/index.shtml

    The genes.gtf file being used came from ftp://igenome:[email protected]_hg19.tar.gz

    They are both from UCSC hg19 so I wasn't expecting any compatability issue.

    Can somebody please advise?

    Many thanks in advance!

    Recent Advances in Sequencing Analysis Tools
    by seqadmin


    The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

    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...
