|Association Mapping and Population Genetics in Vervets||
Scientists: Yu S. Huang et al. (Center for Neurobehavioral Genetics, UCLA)
As the second OWM (old world monkey) sequenced (the first is Rhesus macaque), vervets, unlike the great apes who are mostly in near-extinction status, are widely available for biomedical research. (Rhesus is widely available in India but the export restriction imposed by the Indian government makes it less ideal for biomedical research).Read more...

The Brain Span project seeks to find when and where in the brain a gene is expressed. This information holds clues to potential causes of disease. A recent study found that forms of a gene associated with schizophrenia are over-expressed in the fetal brain. To make such discoveries about what is abnormal, scientists first need to know what the normal patterns of gene expression are during development.Read more...

|Combined CNV Detection||
This workflow combines results from the GNOSIS CNV (Copy Number Variation) detection algorithm and PennCNV detection algorithm (including X-Chromosome detection) to produce a file containing Merged CNVs. It then processes these further to compare the results with a list of Common CNVs, and assesses the overlap of parent and children CNVs. Finally it annotates the results.Read more...
The USC Epigenome Center is currently using the Illumina Genetic Analyzer (GA) system to generate high throughput DNA sequence data (up to 8 billion nucleotides per week) to map the epigenetic state of human cells on a genome-wide scale.
Scientists: Ben Berman et al. (USC)
This application splits sequence files into multiple parts and converts them to the appropriate file format. Then it filters out noisy and contaminating sequences to maps them to their genomic locations. From the individual mapping steps, it merges them into a single global map and uses sequence maps to calculate the sequence density at each position in the genome. This application has a footprint of 6GB of data.Read more...
|Genomic Studies of Mental Disorders||
The computational portal developed for the Center for Genomic Studies of Mental Disorders uses Pegasus to manage workflows for genetic population studies. This portal uses the Wings (url) workflow composition system and Pegasus to enable scientists to launch an analysis based on the available workflow template. Below is a screenshot of the portal Workflow Gallery.
Scientists: Chris Mason, Cornell Medical School; Yolanda Gil, ISI
Scientists at OSU use Pegasus for mass-spectrometry-based proteomics. Proteomics workflows have been executed on local clusters and cloud resources.
Example proteomic workflow: a) Pegasus workflow template. Square boxes with double lines represent file collections and the ellipses with double boundary represent parallel jobs. b) Implementation of workflow for clustering of five shotgun proteomic data sets. c) Hierarchical cluster analysis of the shotgun proteomic data.Read more...
|Quality Control of Population Studies||
This workflow aims to indicate discrepancy in the data coming from different group and checks of concordance on the genotype calls against HapMap genotypes. Initially, it was a big R scripts which computed all the steps at once, sequentially. We have split the code into different steps/tasks to represent them as workflow. As a result, we manage to execute the whole workflow within 30 min on a small cluster compare to the 4 hours of the initial sequential version.Read more...
SeqWare (http://sourceforge.net/projects/seqware/) is an open source software developed at UCLA.
