fMRI Artefact Rejection and Sleep Scoring Toolbox

الملخص EN

We started writing the “fMRI artefact rejection and sleep scoring toolbox”, or “FAST”, to process our sleep EEG-fMRI data, that is, the simultaneous recording of electroencephalographic and functional magnetic resonance imaging data acquired while a subject is asleep.

FAST tackles three crucial issues typical of this kind of data: (1) data manipulation (viewing, comparing, chunking, etc.) of long continuous M/EEG recordings, (2) rejection of the fMRI-induced artefact in the EEG signal, and (3) manual sleep-scoring of the M/EEG recording.

Currently, the toolbox can efficiently deal with these issues via a GUI, SPM8 batching system or hand-written script.

The tools developed are, of course, also useful for other EEG applications, for example, involving simultaneous EEG-fMRI acquisition, continuous EEG eye-balling, and manipulation.

Even though the toolbox was originally devised for EEG data, it will also gracefully handle MEG data without any problem.

“FAST” is developed in Matlab as an add-on toolbox for SPM8 and, therefore, internally uses its SPM8-meeg data format.

“FAST” is available for free, under the GNU-GPL.
