  • Error in CummeRbund

    Hi everyone,

    I am new to R and cummeRbund, but I would like to share with you a problem that occurred to me.

    I'm tryin to build a cufflinks database to analyze which genes are more expressed in IPSc VS normal cells,and I put in my working directory all the files that the company who did the run sent me.

    First question that I wanted to ask you: which KInd of files I have to put inside the dir? I mean I have two folders:cufflinks and cuff diff,Inside of cufflinks there are 3 files: genes.fpkm_tracking,isoforms.fpkm_tracking,transcripts.gtf and in the cuffdiff there another file called genes.fpkm_tracking and isoforms.fpkm,which one i have to put inside the working directory?

    Second question: when I try to build the cuffdata.db this the error that comes out:
    cuff<-readCufflinks(genome="Hg38",gtfFile="transcripts.gtf",rebuild=T)

    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...
