--- Input
sys_dir : MEG data dir
sys_id : MEG system ID
eeg_info : MEG header info
--- Optional Input
param.time_win = [Tstart Tend]: [ms]
param.trials = trial index to extract
--- Output:
eeg_info : structure with following field
.nch, % number of EEG channel
.nsamp, % sampling number of measurement
.nrept, % repeat number
.sampf, % sampling frequency
.ch_name % channel name
.ad_factor % AD multiplicative factor to convert EEG data to [V]
eeg( Nchannel, Tsample, Nrepeat) % measured fields [T]
