    softwares for bacterial RNA-Seq analysis?

    Hi everyone,
    in our lab we are going to try to do some bacterial RNA-Seq run with our Ion Torrent.

    Anyone with experience in Bacterial RNA-Seq that can suggest the best softwares to analyze the data?

    We prefer to run software locally on our servers!

    Thanks everyone!

    You may try Subread, which is a splice-aware aligner and is very powerful in aligning long reads. It tolerates quite a lot of errors in the mapping while maintaining its high accuracy at the same time, making it particularly suitable for mapping reads generated from Ion Torrent platform which is known to have a high sequencing error rate.

      Thanks, i'll try it!

      Do you know any paper/review to be used as a first-time guide to RNA-seq?

      EDIT: you mentioned splicing, i'm going to analyze only bacterial data, so no splicing, can i use eukaryotic tools without problems?

        softwares for bacterial RNA-Seq analysis?

        There is a review article, Studying bacterial transcriptomes using RNA-seq,
        in Current Opinion in Microbiology, which should be useful if you are working on bacteria.

        Genome-wide studies of bacterial gene expression are shifting from microarray technology to second generation sequencing platforms. RNA-seq has a number of advantages over hybridization-based techniques, such as annotation-independent detection of ...


        The SEQanswers SeqWiki has a how-to section on RNA-Seq analysis,



        As good starting points for RNA-Seq and data analysis of RNA-Seq in general,
        see this review article by Wong et al in Nature Reviews Genetics,



        and this review by Pepke et al in Nature Methods on computational methods,

          Thanks so much,
          i'll read those in the week end!!

            Hi guys,
            Which is the best pipeline to use for analysis of strand-specific bacterial RNAseq data (illumina platform). i have tried bowtie2 (using default settings), cufflinks (cuffmerge and cuffdiff) pipeline but i'm not getting any differentially expressed genes. Which pipeline is most ideal for bacterial DE analysis.
            I have read through most of the articles cited above but i still cant get any DE genes.
            Thanx,
            Stan

              Mine is:

              -mapping with TMAP (Ion Torrent specific)
              -counting with HTSeq
              -edgeR for differential expression
              -TopGO for enrichment, previously run Blast2GO if working with non-model organism.

              Best, Bernardo

                  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...
