  • RNA CoMPASS v1.0 released!

    RNA CoMPASS, a web-based GUI distributed computational pipeline, provides all-in-one functionality including human transcriptome quantification and the typical endogenous RNA-Sequencing analysis along with the investigation of exogenous sequences. RNA CoMPASS is deployable on either a local cluster or a grid environment managed by PBS submission.

    The key features include,
    Discovery and visualization of exogenous sequences of non-host origin
    * Aligns short RNA sequences against human, virus and bacterial genomes
    * Searches unmapped sequences against human RNA and NT databases
    * Visualizes taxonomic distribution of reads using MEGAN
    * Assembles pools of exogenous reads into longer transcripts with ABySS
    (Currently under development)

    Performs extensive endogenous RNA-Seq analysis for the host organism
    * Calculates genomic feature abundance score at both gene and isoform level
    * Detects differentially expressed genes and isoforms with support for edgeR
    * Generates wiggle files for visualization and signal maps for peak detection
    * Generates alignment report summarizing distribution of read mappings

    The software is available for download at:

    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...
