    Bowtie and Cufflinks

    Hello,

    I have aligned Solexa sequencing data using Bowtie and plan on creating expression profiles using Cufflinks by looking at RPKM values.

    There is one thing I am curious about. Is there a way to compare your alignments to annotated regions, so you can give the reads a name along with an RPKM value? I'm assuming Cufflinks simply gives you a read and it's RPKM, what I would like is to be able to see X gene, X miRNA, X puesdogene has an RPKM value of Y.

    Is there a way to make this possible? Any suggestions would be great.


    Thanks,
    Brandon

    Cufflinks will give you a gene/transcript and its RPKM (if you feed it a gff file). If you don't, it will give you a "made up" gene/transcript and its RPKM.

    RPKM is always in terms of a larger genomic entity, not a single read. Reads per kilobase per million.

      mgogol, thank you for the reply.

      Do you work in bioinformatics here in the Kansas City area? I work at UMKC.

          I'm at KU Med... Looks like KC is representing well.

            I've seen your name around the forum... I went to KU, so it jumped out at me.

              We should all get together sometime for lunch. It would be nice to talk face to face with others that actually understand what you are doing.

                  Kansas City seems to be well represented here.

                    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.

                    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

                    Here are nine questions we think about, in roughly the order they matter, before...
