We have two HP workstations on which Neuromag software runs fine. We also have pre-release versions that run under Linux (Redhat4). These can be called directly from the command line, and will run on a linux box with the minimal current load. See AccessingNeuromagSoftware for more details about these different options.
The Neuromag software consists of several separate programs:
MaxFilter - for applying SSS to averaged or raw data. Removes much noise. Necessary if Active Shielding used. Also vital for movement compensation, and many other features.
Xplotter - for viewing averaged files and doing basic operations (like subtractions)
Xfit - advanced tool for dipole fits (single and multiple ECD) to averaged files
Graph - flexible (though complicated) software for processing both raw data (eg spectral analysis, averaging) and averaged files (eg statistics). Can be batched to do anything with any kinds of data.
Seglab - for segmenting MRIs and creating BEMs
MRILab - for coregistering MRI and MEG data, and creating forward models. Can be used in combination with Xfit for overlaying ECDs on MRIs.
MCE - Minimum Current Estimate, and L1-norm distributed solution
Dicom Access - converting DICOM files to FIFF format. Necessary if you want to use MRILab or SegLab.
