Summary: The webmaster releases apps as freeware, which are developed for support of my own daily magnetoencephalography (MEG).

The followings are magnetoencephalography (MEG) analysis apps developed by the webmaster using MATLAB for the MEGIN system (Neuromag System / TRIUX Neo) for support of my daily work. The webmaster’s apps are based on programs of Dr. Akira Hashizume, a supervisor in my institute. Therefore, following his philosophy, the webmaster publicly releases them as freeware (May 30, 2023).

For Windows 64-bit: hecmeg_win
For Linux 64-bit: hecmeg_lnx

The download is available on GitHub. Here are the steps to download:

  1. Go to the GitHub repository link.
  2. Select the green “Code” button on the top right of the screen.
  3. Choose “Download ZIP” at the bottom.
  4. Extract the downloaded .zip file.

Both versions, Windows and Linux, require MATLAB Runtime R2022b (9.13) (free download) to run separately, which requires approximately 8GB of storage space.

For the Windows version, simply double-click the .exe file to launch.

For the Linux version, navigate to the corresponding directory, right-click on the file, go to Properties, select the Permissions tab, and check “Allow executing file as program.” Then, in the terminal, enter “./run_hecmeg_lnx.sh <deployedMCRroot> args” (e.g., “./run_hecmeg_lnx.sh /neuro/data/ns/MATLAB_Runtime/R2022b”) to launch it.

It can also be used as a viewer for signal information from the MEGIN system. If you wish to perform signal processing in conjunction with DICOM images, it is strongly recommended to use SPM12 for brain extraction. While the performance of brain extraction varies depending on the app, this software can adequately extract the brain within 1 to 5 minutes, making it an excellent choice.

 

Note:

  1. These apps are intended for the support of webmaster’s personal research and analysis.
  2. The webmaster is not liable for any damages caused by their use.
  3. Whether for clinical or research purposes, official reports require analysis using the official apps provided with the MEG systems.
  4. These are only compatible with the MEGIN systems.
  5. Since the apps have only been validated with the MEGIN system used by the webmaster, it is strongly anticipated that they may not be compatible with systems of other institutes, even if they are MEGIN systems. If you have sample FIFF files, please contact the webmaster through the comments window. Then, the webmaster will make efforts to provide support.
  6. Due to their personal use, it is strongly anticipated that there are many bugs and errors left. If you encounter any, please contact the webmaster through the comments window. Then, the webmaster will make efforts to provide support.
