  • New microRNA suite of functionality in CLC bio's Genomic Workbench

    The Genomics Workbench 4.0 was released on Wednesday June 15th and included in the improvements are a suite of tools for Small RNA analysis.

    This new functionality is designed to facilitate trimming of sequencing reads, counting and annotating of the resulting tags using miRBase or other annotation sources, and performing expression analysis of the results. The tools are general and flexible enough to accommodate a variety of data sets and applications within small RNA profiling, including the counting and annotation of both microRNAs and other non-coding RNAs from any organism. Illumina, 454 and SOLiD sequencing platforms are supported. For SOLiD, adapter trimming and annotation is done in color space.

    The annotation function is designed to make special use of the information in miRBase but more general references can be used as well.

    There are generally two approaches to the analysis of microRNAs or other smallRNAs: (1) count the different types of small RNAs in the data and compare them to databases of microRNAs or other smallRNAs, or (2) map the small RNAs to an annotated reference genome and count the numbers of reads mapped to regions which have smallRNAs annotated. The approach taken by CLC Genomics Workbench is (1). This approach has the advantage that it does not require an annotated genome for mapping -- you can use the sequences in miRBase or any other sequence list of smallRNAs of interest to annotate the small RNAs. In addition, small RNAs that would not have mapped to the genome (e.g. when lacking a high-quality reference genome or if the RNAs have not been transcribed from the host genome) can still be measured and their expression levels compared. The methods and tools developed for CLC Genomics Workbench are inspired by the findings and methods described in [Creighton et al., 2009], [Wyman et al., 2009], [Morin et al., 2008] and [Stark et al., 2010].

    Look at the tutorials on http://www.clcbio.com/tutorials to see examples of analyzing specific data sets. Also fully functional free trial versions of the Genomics Workbench are available for testing with your data.

    According to at least one of the beta testers...this suite of applications for miRNA analysis is a "whole new world."

    I am using CLC Bio Genomics Workbench 4.7.2 to do smallRNA analysis. Everything works fine and it is very easy to use. However, I am having trouble while looking for novel miRNAs. The user manual do not have the details on how to extract a region and do RNA secondary structure prediction.

    Can anyone provide the details on how to extract a region of the genome and predict the presence of novel miRNAs.

    Thank you.

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
