  • ASAP: Advanced Sequence Automated Pipeline

    Introducing ASAP: Advanced Sequencing Automated Pipeline
    ASAP is an open source pipeline designed to assist users in managing various jobs associated with processing HiSeq data on a cluster or in serial.

    Capabilities
    The software is highly modular, so users can selectively use or skip any of the steps including:
    • Alignment with BWA
    • Local Realignment around known Variants with GATK
    • Quality score recalibration with GATK
    • SNP calls with Samtools, GATK, GlfMultiples or a consensus of 2 or more
    • INDEL calls with Samtools, GATK or a consensus
    • Annotation using ANNOVAR
    • Users can import bam files into a new or pre-existing pipeline and integrate those bams with bams created by ASAP for further processing (optional) and variant calls.


    In addition to preparation, submission and monitoring of the processing scripts, ASAP also provides tools for slicing up fastq data for more parallel alignment, some basic QC including Ti/Tv ratios, heterozygous/homozygous alternate ratios, etc. to quickly identify issues before beginning analysis.

    Data Integrity
    To ensure only hi-quality data is used, a single job will fail if one of the child jobs fails or if quota issues prevent a successful copy. This means that no partially completed data slips through.

    Software Download
    Please feel free to have a look, and ask me any questions. The software can be freely downloaded at: http://biostat.mc.vanderbilt.edu/wiki/Main/ASAP There is a small tutorial with step by step instructions on how to use ASAP to install any missing components as well as run some data through the process.

    Caveats
    Currently, ASAP is designed for paired-end sequence data from Illumina’s HiSEQ platform, but we are interested in working with other groups to make it work with other popular platforms as well. It should run on most (hopefully all) PBS and SGE clusters as well as in serial mode, however, it is possible to create support for other cluster systems.

    Extensibility
    Adding some new functionality, such as support for an alternate aligner or SNP caller should be relatively easy, but introducing entirely new functionality might require the knowledge of Ruby programming.

    ASAP v1.1.4 Released

    We have updated ASAP to version 1.1.4. Some features that have been added since the initial release include:
    • Support for processing single end reads (with bwa)
    • Bam Summaries with QPLOT
    • Optional support for GATK 2.x
    • Ability to automatically download most of the component applications, if they aren't already available
    • Many bug fixes and tweaks to make the software more user friendly and extendable.


    We have posted a short tutorial on the website to allow users to try it out without spending too much time.

    If you are tired of cobbling together dozens of scripts to create the jobs necessary to process your sequence data, digging through log files trying to identify which jobs failed due to a sick cluster node, or are just getting your first taste of sequence data, ASAP might prove to be a valuable time saver.

      ASAP v1.1.7 Released

      An updated version to ASAP has been released including a handful of bug fixes as well adding some features that might be of interest to users including:
      • Serial execution can now be run on multiple processors at once (this is in addition to the multithreaded options previously available). The number of jobs run at once is controlled by the user.
      • Batch Realignment now gives users control over how many samples to realign together, providing much faster realignment for large batches, while allowing the user to benefit from sharing information across samples.
      • Improved settings for baseline configurations with a focus on greater parallelizability.


      The paper has also been published at BMC Research Notes: http://www.biomedcentral.com/1756-0500/6/5

        Hello etorstenson,

        Unfortunately I am not being able to download it from the specified address which is http://chgr.mc.vanderbilt.edu/lilab/asap-v1.1.7.tgz. So, can you kindly provide me working link. I want to try it out since I am new to NGS and i really like the pipeline specified. Thanks

        Regards

          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...

          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...
