    But no plain bowtie2-build (the -l is for 64-bit indexes but they are not supported by TopHat as yet)?

      No, I have a plain bowtie2-build as well.

        I am stumped.

        Give a real sample a try to see if that works.

          Damn =P I'll do that and see if it works. Thanks for all your help, regardless!

            Downgrading to Bowtie 2.2.2 did the trick! Must have been a bug or something in 2.2.3...

              I was using Bowtie 2.2.1. Won't upgrade to 2.2.3.

                Error in testing the installation of Tophat

                I'm a brand new person in RNA-Seq and a beginner in bioinformatics as well. So my apologies if my question is naïve or it has been posted already. Recently I installed Tophat v2.0.12, with Bowtie, SAMtools and Boost libraries, in Ubuntu 12.04 lts 32-bits. However when I tried to test the installation

                tophat -r 20 test_ref reads_1.fq reads_2.fq


                I got this error:



                [2014-07-04 10:52:25] Beginning TopHat run (v2.0.12)
                -----------------------------------------------
                [2014-07-04 10:52:25] Checking for Bowtie
                Bowtie 2 not found, checking for older version..
                Error: TopHat requires Bowtie 0.12.9 or later

                It seems to me there is a problem with the version of bowtie I have installed, perhaps to old? If you could please give some clue about how to solve this problem?
                Thanks in advanced

                  If you only have bowtie (v.1.x) installed then you may need to add the following option

                  Code:
                  $ tophat --bowtie1 -r 20 test_ref reads_1.fq reads_2.fq
                  It may be better to install bowtie2 (http://sourceforge.net/projects/bowt...les/bowtie2/)?

                  Or it may be a simple fix of adjusting your $PATH so bowtie directories are included there.

                      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...

                      Current Approaches to Protein Sequencing
                      by seqadmin


                      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
