vb_test_make_trial_file
----- Batch script for making trial file from continuous data -----
Make trial data files after extracting trials from continuous raw data
[data, ch_info] = vb_msrmnt_make_trial_data(proc_spec)
：proc_spec : <required> <<struct>>
: .root_dir : <optional> data directory of base meg/eeg file
: and trig_file ['.']
.trig_file : <conditionally required> <<file>>
: trigger file name without path
: this file is expected to have data as follows:
: .parm.data_file (without path) : base file
: .trig [1 x Ntrial]
: .parm.Pretrigger_ms : pretrigger [msec]
: .parm.Posttrigger_ms : posttrigger [msec]
: .parm.fsamp : sampling frequency [Hz]
: if this is invalid and .proc_parm field is not
: specified, it is error.
.new_file : <optional> new MEG/EEG filename
.new_bin_dir : <optional> binaly external data directory
: *ONLY FOR MEG*
: This is relative path from '.new_file'
: if this is not specified, data is stored internally
.proc_parm : <optional> <<struct>>
: .Pretrigger_ms : Pretrigger period [msec]
: .Posttrigger_ms : Posttrigger period [msec]
: .sample_freq : sampling frequency [Hz]
: .data_file : base [meg/eeg] file (no path)
: .trigger : list of trigger samples
: : [1 x Ntrial]
: if these are specified,
: they overwrite the setting values of trig_file
：trig_file にトリガファイルを指定します
：base file は trig_file に保存されたファイル名parm.data_fileを使用
：通常はトリガファイルから取得したトリガ情報を使用しますが、
：proc_parm を指定すれば、このトリガ情報が優先されます
：トリガファイルを作成した元データではなく、フィルタ処理されたデータから
トライアルファイルを作成する時は、proc_parm.data_file を指定する
：.new_bin_dir でデータの外部保存ディレクトリを指定します(MEGのみ)
：.new_bin_dir が指定されない場合は、切り出したデータを内部保存します
