Read and write ffA volume formats

Users can easily move 3D volume data between Matlab and ffA's SVI Pro / SEA 3D Pro

ffA provide world leading 3D Seismic Analysis Software and Services to the oil and gas industry.

ffA software extracts geological features from 3D seismic data, objectively and more rapidly than with conventional techniques to help geoscientists and engineers to make better decisions with higher confidence, in less time.

ffA's SVI Pro and SEA 3D Pro desktop applications provide an extensive range of advanced analysis and visualisation capabilities for large seismic datasets.

The collection of m-files allow .ffa format volumes to be read, created and written to, allowing users to work together with both ffA Software and Matlab.
