Multiscale Electrophysiology Format
Multiscale Electrophysiology Format (MEF) was developed to handle the large amounts of data produced by large-scale
HIPAA requirements for patient privacy
when transmitting data across an open network.
Compressed data is stored in independent blocks to allow direct access to the data, facilitate parallel processing and limit the effects of potential damage to files. Data fidelity is ensured by a 32-bit cyclic redundancy check in each compressed data block using the
Koopman polynomial (0xEB31D82E), which has a Hamming distance
of from 4 to 114 kbits.
A formal specification [1] and source code [2] are available online. MEF_import[3] is an EEGLAB plugin to import MEF data into EEGLAB.
