    Cuffdiff GTF file ?

    Hi,

    I'm trying to analyze a samples of a mouse stem cell during different stages of differentiation, for that I first aligned the RNA-Seq reads corresponding to the different samples to an index files using tophat and then I processed the Tophat output tough Cufflinks.

    Now I'm trying to compare different samples using Cuffdiff however I've hit a roadblock.

    Initially I was convinced that I had to use with Cuffdiff a GTF file produced by combining with Cuffmearge or Cuffcompare the transcripts.gtf files produced by Cufflinks for the samples being compared, however I've read a on-line tutorial that recommended using instead the GTF that served as index for the Tophat runs.

    Could somebody with more experience point to correct file to use ?

    Thanks in advanced.

    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
    by GATTACAT
    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.
