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.

EMSE in the Times
5.08.10 EMSE user Dr John Kounios of Drexel University has been interviewed by the New York Times for their 8 May article "Charting Creativity". Be sure to see the screenshot from EMSE on page 2. Our congratulations to John and his colleagues, not only for advancing the field, but for making it accessible to a broader public.

BioMag 2010
3.11.10 Alexei Ossadtchi and Richard Greenblatt will be attending Biomag 2010, March 28-April 1, 2010, in Dubrovnik Croatia. Although Source Signal Imaging will not be a commercial exhibitor at the meeting, Alex and Richard will be presenting poster W-I T4-2-4 on Wednesday, March 31, in the Levantera Hall. The poster describes recent work on source estimation from time-frequency MEG data. We look forward to meeting with EMSE users at the meeting. Please stop by the poster, or contact Richard by email (reg at sourcesignal dot com) if you would like to schedule a specific meeting time. Also, don’t forget the upcoming EMSE workshop April 15-16, Hamilton Ontario, Canada.  There is still time to register at http://www.sourcesignal.com/workshops.html.

EMSE 5.3 Full Release Version: available for download here
1.28.10 We have added many new features and improvements:

• Batch averaging and peak detection to automate ERP analysis in the time and frequency domains
• Source Estimation enhancements -  DICS in the time-frequency domain, newly optimized BEM, channel groups for dipole fitting, multistart dipole fitting, improved dipole confidence intervals, sequential dipole fits to selected data intervals, and a streamlined user interface and display
• New file readers for Elekta/Neuromag, Grass Telefactor, BMSI, EDF+
• Output a new file from user-selected intervals, preserving event markers using event-based epochs or variable length segments; up- or down-sample to new effective sampling rate
• Hilbert transform and Global field power filters
• Blind event review mode – manual (visual) artifact rejection when the reviewer does not have access to the event types
• Workspace auto-sync keeps your workspace up-to-date between Data Editor and MR Viewer modules, auto-updating when a change is detected

EMSE 5.3 Release Candidate 2 is here
1.16.09 We have added many new features and improvements: Click here for details.

Cortech Solutions at SPR
9.24.08 Cortech Solutions will be exhibiting at the 48th annual Society for Psychophysiological Research conference Oct. 1-5, 2008 in Austin, Texas. Our own Mark Pflieger will be on hand to answer any EMSE questions you may have. If you are in the Austin area please feel free to drop by.

EMSE 5.3 Release Candidate 1 is here
8.21.08 In our software development model, a ‘release candidate’ means that we have completed new feature development for this version.  The software is now stabilized for testing and bug fixing. All users of EMSE 5.3 beta versions are strongly encouraged to download this version--we think you will find it significantly more stable than any of the betas. We have added many new features and improvements: Click here for details.

Upcoming EMSE Workshop
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.
