Workflow Gallery

Gallery Info

Pegasus is curently being used in a broad range of applications. This gallery categorizes the workflow runs by application.
You can click on an application link to access the archived workflow runs for that Application.

The Application page shows all the runs of that workflow type along with a short summary of the workflow .
The runs shown here are actual runs done through Pegasus using actual data and executables.

There is also a PegasusHUB that provides a curated collection of open source Pegasus workflow repositories hosted at GitHub and allows user to execute them in various execution environments.
Workflow type Structure


A RseqFlow workflow which can implement a set of 
RNA-Seq analysis, such as performing quality 
control (QC) for sequencing data, generating 
signal tracks of mapped reads, calculating 
expression levels, and identifying 
differentially expressed genes.


The Galactic Plane workflow will use the 
Montage image mosaic engine to transform 
all the images in 17 sky surveys to a 
common pixel scale of 1 second or arc, 
where all the pixels are co-registered 
on the sky and represented in Galactic 
coordinates and the Cartesian projection. 


NASA’s Infared Processing and Analysis 
Center (IPAC) use workflow technologies to 
process the large amount of data produced 
by the Kepler mission. IPAC has developed
a set of analysis codes to compute periodograms
from light curves. These periodograms reveal 
periodic signals in the light curves that arise 
from transiting planets and stellar variability.


The DART workflows use DART Music Information Retrieval 
(MIR) research platform to perform a parameter sweep 
experiment in order to discover the optimal parameter
settings for the sub-harmonic summation pitch 
detection algorithm.

DART has become a viable platform from which to conduct
MIR experiments and research. The application currently
performs a series of sub-algorithms on a several audio files
(downloaded by the user in the current prototype) 
that make up a pitch detection algorithm
(sub-harmonic summation). Ingrained in many MIR processes 
is the necessity to determine pitch, which can be 
computationally demanding.


The SIPHT workflow, from the
bioinformatics project at Harvard,
is used to automate the search for
untranslated RNAs (sRNAs) for bacterial
replicons in the NCBI database.  

Synthetic Scec

A Synthetic Workflow that corresponds
to a full Cybershake site from 2009
production run. All the jobs are run


The CyberShake workflow is used
by the Southern Calfornia Earthquake
Center to characterize
earthquake hazards in a region.


Broadband platform enables researchers to combine
long period (<1.0Hz) deterministic seismograms 
with high frequency (~10Hz) stochastic seismograms.


The epigenomics workflow created
by the USC Epigenome Center
and the Pegasus Team is used to
automate various operations
in genome sequence processing.


LIGO workflow is used to generate and
analyze gravitational waveforms
from data collected during the
coalescing of compact binary systems. 


The Montage application created
by NASA/IPAC stitches together multiple
input images to create
custom mosaics of the sky.
