Overview

Vespa is an integrated, open source, open development platform for magnetic resonance spectroscopy (MRS) research. It contains four software applications, written in Python, called:

Pulse - for RF pulse design
Simulation - allows spectral simulation and prototyping
DataSim - an application for creating synthetic MRS data sets
Analysis - interactive spectral data processing and analysis

These applications can be run separately, but can also communicate via a shared database of objects/results. Integration allows one application to use the output from another as input. For example, Simulation can make use of an RF pulse designed in Pulse to create a more realistic MR simulation.

The Vespa project addresses previous software limitations such as: non-standard data access, closed source and multiple language software (that complicate algorithm extension), and a lack of integration between programs.

Background

The Vespa package is an extensive redesign of three previous MRS software tools:

MatPulse (Pulse) - software for RF pulse design written in Matlab,
GAVA/Gamma (Simulation) - software for spectral simulation code in IDL
IDL_Vespa (Analysis) - spectral data processing and analysis code in IDL

Thanks to the NIH (grant number 1R01EB008387-01A1) for funding the maintenance and extension of these separate applications into a combined environment based entirely on the Python language.
