Talk:Mffimport

The attached functions pop_readegimff() and readegimff() might be of use to EEGLAB users with EEG amplifiers made by EGI Inc. (http://www.egi.com). These functions add functionality to import the new open Meta File Format (MFF) introduced by EGI since Net Station 4.5. This new format, and hence these functions come with the following advantages:

1. Fast, direct import of original recording into EEGLAB, without having to first convert to Net Station Simple Binary (NSF) format.

2. Preservation of all event information present in the original recording, including an unlimited number of key code-value pairs per event (this information is lost when using pop_readegi with NSF format files).

3. Support for importing both continuous and epoched data in MFF files.

4. Support for importing polygraph data (EMG, EKG, etc.) recorded by EGI's Polygraph Input Box.

5. Ability to import a specified subsection of samples from the data.

readegimff() uses a Java-based MATLAB API provided by EGI. The files included in this API and the code for pop_readegimff() and readegimff() are included in the attached zip.
