Synthetic Magnetometry: The SAMsrcV3 Analysis Suite

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).

Features include:

Flexible control over active, control, and noise covariance matrices
Dual-state ERF imaging
Realistic head models
Hilbert envelope time series computation for connectivity
Experimental refinement of MRI coregistration based on Freesurfer normals
More efficient workflow
Command-line interface for maximal flexibility

-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.
+Features include:
+* Flexible control over active, control, and noise covariance matrices
+* Dual-state ERF imaging
+* Realistic head models
+* Hilbert envelope time series computation for connectivity
+* Experimental refinement of MRI coregistration based on Freesurfer normals
+* More efficient workflow
+* Command-line interface for maximal flexibility
-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 For example, the old SAMsrc program has been replaced by a set of several new programs with a modern command-line interface.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.

-A wiki containing documentation for the SAM suite is [https://kurage.nimh.nih.gov/samdoc/ here]. It's still a work in progress.
