Magma is a data manipulation application that handles all seismic data formats from a variety of media types. Magma can provide fast transfer of information to and from High Capacity Media, hard disk and across networks, but is also able to handle data recorded on historic 21 and 9 track drives. It is a flexible seismic QC tool and efficiently handles seismic input/output and is designed to transcribe, copy, read and reformat data. The Magmaprogram is modular with input modules for the standard SEG seismic formats - other formats are added as the need arises. There are also modules for output to SEGY and for producing plots of seismic traces.
