Welcome to Source Signal Imaging, developers of EMSE Suite. EMSE Suite is a Windows-based software toolkit for 4D multimodal functional brain imaging, including analysis, source estimation, image processing, and visualization. MEG/EEG and MRI/fMRI datasets from many vendors and standard formats may be combined to obtain results not available from independent analyses of the separate modalities. First introduced in 1996, and now used by clinicians and researchers worldwide, EMSE Suite has a modular architecture, rich feature set and relatively low cost.

7.31.08 There will be a one-day EMSE Workshop in Tokyo Japan on Monday September 1, 2008, following the Biomag 2008 conference, to be held in Sapporo.  The workshop, given by Richard Greenblatt, will cover the basics of EMSE Suite, with a special emphasis on time-frequency analysis.  Bring your laptop, install the latest EMSE software, and get hands-on experience and advice from the one of the developers. For information on workshop location and registration, see http://www.miyuki-net.co.jp/jp/calendar/EMSE_workshop09012008.pdf (in Japanese), or contact sawai@miyuki-net.co.jp or sales@sourcesignal.com.  To see the workshop schedule (in English), click here.

EMSE 5.3 beta 5 is here!
3.28.08 Download the latest release of EMSE 5.3 beta and try out the many new features and improvements we have incorporated, including: re-sampling time series in the Data Editor; electrocorticogram (ECoG) visualization; and channel group support in topographic mapping. Topo mapping also supports time-frequency analysis display and Neuromag vector magnitude display. Our unique Epilepsy Tools have an improved user interface for spikes and support spike template matching. Power spectral density (PSD) extensions now allow for variable-length intervals. Two new filters are in the Filter Pipeline: global field power and the Hilbert transform. Usability enhancements in the Data Editor include grouping channels by name (as well as saving/restoring channel groupings), more contextual menus (accessed by right-clicking), improved auto-updating, blind event review, and modeless dialogs that allow you to work while leaving them open. New file formats are supported, such as Neuromag, Grass Telefactor and BMSI. The Source Estimator module has a newly optimized boundary element (BEM) model, channel group support, multistart dipole fitting and an improved dipole display. MR Viewer has new support for user-selected point registration and labelled points. Visualizer has improved integration with ECoG data as well as user-defined display preferences. Workspaces now auto-refresh when changes made in one module affect a workspace in another module. Locator now has more  advanced editing capabilities to correct points that are incorrectly digitized. Download EMSE 5.3 beta 5 here. For more details, see what's new.
