EMSE 6.4 is the current stable release of our flagship EEG and MEG signal processing and source estimation software platform. The conversion from 32-bit to 64-bit was a long and intensive process for our development team in LA Mesa, CA, and it sets the stage for bigger developments to come.
For EMSE users, this new 64-bit version of the software will mean virtually unlimited data file size and faster operation when working with datasets containing high bit depth (24-bit and 32-bit), large numbers of channels (128, 160, and 256), and ultra high sampling rates (e.g. Biosemi ActiveTwo Hyper-Sampling Edition at 262 kHz per channel and Bittium NeurOne at 80 kHz per channel).
In addition to this important milestone in EMSE development, a long list of new features have been implemented in EMSE and existing features have been refined to further improve performance. Here is a short list of some of the latest additions and improvements now available in EMSE 6.4:
- Improved ASCII/binary import
- Improved Batch > Peak & Area measures with support for large workspaces
- Improved FIR/IIR transfer function visualization
- Improved ECoG custom probe handling
- Improved saving to EGI segmented simple binary with events
- Improved handling of Polymate DAT24 format
- Improved handling of sparse matrix with LORETA (classic)
- Pulse artifact rejection filter can now be applied to passthrough channels
- Improved copy/paste functionality for filter pipelines
- Add frequency band ratio map definitions (e.g., theta/beta)
- Improved reading of Nihon Kohden events
- New middle layer commands to facilitate automation
- Frequency domain peak detection
- Surf2Surf: convex hull using shrink wrap
- Vol2Vol: Merge mode; extract labeled points; affine labeled points normalization
- Improve histogram display in MR View
In case you have not kept up to date with EMSE improvements, here is a short list of improvements from EMSE 5.60 to 5.61, all of which are also incorporated in the new EMSE 6.4:
- Conversion of MATLAB exported data to EMSE binary format (MatExport2Bin)
- Export of GSR data to Ledalab Text Type 1 format (SaveAsLedalab)
- Polymate: Reconciliation of autoscaling and absolute scaling for various channels
- Support for BDF+ format (24-bit EDF+ with annotations)
- 2D mapping of coherence links, also including links for:
- Cross-spectral density
- Imaginary part of coherency
- Imaginary part of cross-spectral density
- Imaginary part of coherency (normalized) and imaginary part of cross-spectral density
(unnormalized) - Coherence export to Excel with one worksheet per “coherence reference”
- SaveAs2 batch script command for large continuous files with an IIR filter in the pipeline
- Batch script commands for integration with FreeSurfer cortical and BEM surfaces
- AppendFilter batch script command
- Use an .aux file to rename channels at the level of raw data (without altering the
original data) - PLA = Phase-Locking Angle in time-frequency analysis
- User-defined sets of frequency bands for topographic mapping with IFCN and IPEG definitions
- Automatic marking of EEG outliers using the Outliers from Good Data (OFGD) method
- AutoMark Blink, Clean, and HEOG intervals for OAC Spatial Filter
- Event Overlay with AddResponses mode (adds behavioral responses to events)
- Align and merge LiveTrack eye tracking data with EEG (SynchTimeSeries command)
- IBI, HR, and logHR (log heart rate) channels derived from ECG R-R peak intervals (HRV
command) - Export Excel XLSX format:
- XLSX result generated by Utilities | Customize peak output
- Average time series for a specified time range
- Power spectral density for a specified frequency range
- Time-frequency for specified time and frequency ranges (one sheet per channel)
- SaveAsExcel batch script command for average time series and power spectral density.
- Ricoh MEG support
- Restored user interface for Epilepsy ASPIRE.
Now is a great time to upgrade to EMSE 6.4!
