eeprobe/asa data importer for EEGLAB (MATLAB)

MATLAB importer for eeprobe (cnt/avr) data format. Can be used as plugin for EEGLAB MATLAB toolbox as well.
Supported versions of MATLAB:

  • Windows MATLAB 7.5 (R2007b/32bit)
  • Windows MATLAB 7.5 (R2007b/64bit)
  • Mac MATLAB 7.0 (PPC only/32bit)
  • Linux MATLAB 7.4 (R2007a/32bit)
  • Linux MATALB 7.4 (R2007b/64bit)

We provide several precompiled MATLAB plugins download here >>

Early 2010, we made the code to our MATLAB/EEGLAB importer and exporter open source.

The file format provides functions for storage of EEG/ERP/MEG data as 32-bit values, and includes a very efficient compression algorithm. Encoding/decoding from the compressed data is performed automatically through the libeep interface functions. Software library that deals with reading and writing RIFF-format CNT/AVR-files. The plugins below here are provided as a courtesy. We encourage our users to grab the source-code and compile it themselves for the most recent version of MATLAB/EEGLAB.

In November of 2013, changes were made to the library to allow cnt files to grow larger than 2GB. To accomplish this, the internal pointers in the file-format uses 64-bit offsets, instead of 32-bit. Please note, that files created with 64-bit offsets cannot be read by older versions of LIBEEP that don't support this. Please update your software if you encounter this problem.
