    Error with RSEM/eXpress/cufflinks

    Hi All! Hopefully someone can help me here, I'm trying to quantify expression from bowtie2 output.
    When I try to used RSEM/eXpress, it fails because it detects that there is something in the header twice e.g. from eXpress

    ERROR: Target 'RUMOBE_01512' appears multiple times in BAM header.

    RSEM gives pretty much the same thing. Cufflinks however fails because
    "Error: sort order of reads in BAMs must be the same" although I suspect it's because of the same thing that's causing the other 2 guys to mess up.

    I didn't build the reference used for mapping, but I know it's made of non redundant nucleotide sequences from multiple different bacteria, and the actual alignment was done with bowtie2. So what I'm putting into eXpress/RSEM/cufflinks is a bam file that has been sorted and I've run rmdup on it.

    Any idea on how to fix this without going back to the reference and re-aligning?

    Thanks

    Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
    by SEQadmin2



    Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

    Cancer Drug Resistance: The Lingering Barrier to Rising Survival
    by SEQadmin2



    Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

    There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

    Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing

    Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
