The SAMsrcV3 MEG Analysis Suite

Synthetic Aperture Magnetometry

The programs documented here implement the latest advances in MEG source localization. Compared with the older CTF tools, there are many new features (some of them experimental). True within-subject statistics are now available, including a non-parametric test in addition to the usual t and F tests. There is much better handling of shorter time windows, a more flexible control over active, control, and noise covariance matrices, dual-state ERF imaging, realistic head models, and several flavors of multipole source imaging that are available, though some of these latter features are still considered experimental.

There is also a new work flow resulting from a more efficient separation of functionality. For example, the old SAMsrc program has been replaced by a set of several new programs with a modern command-line interface. The old CTF tools were normally installed in /opt/ctf. The new set of programs will generally be copied into a user’s $HOME/bin directory. Many of the old tools are still useful and necessary.
