eeg_load_scan4_cnt

 eeg_load_scan4_cnt - Load a scan4.1+ CNT file
 
 cnt = eeg_load_scan4_cnt('filename',channels,range)
 
 filename   -  Filename string
 channels   -  see eeg_load_scan4_cnt_data,
               default is 'all' channels (sensors/electrodes)
 range      -  see eeg_load_scan4_cnt_data,
               1x2 start/stop sample points
               eg, [1 1000] loads first 1000 points

               NOTE: default range is [1 1000], not
               all of the CNT file!  If you want it all,
               specify 'all'

 cnt        -  struct, see eeg_load_scan4_cnt_data
