vb_ykgwfile_load_calibinfo

PURPOSE ^

set calibration information into meg_info

SYNOPSIS ^

function [meg_info] = vb_ykgwfile_load_calibinfo(ykgwfile, meg_info)

DESCRIPTION ^

 set calibration information into meg_info

 [usage]
   [meg_info] = vb_ykgwfile_load_calibinfo(ykgwfile, meg_info)

 [input]
   ykgwfile : <required> <<file>> yokogawa file path
   meg_info : <optional> <<struct>> base of information
            :  if this is not specified or is empty, meg_info will be created
            :  newly

 [output]
   meg_info : <<struct>> updated meg_info
            :  .sensor_gain   [n_channel x 1]
            :  .sensor_offset [n_channel x 1]
            :  .FLL_gain      [n_fll x 1]
            :  .device_info.acq_info.data_bit_len [1 x 1 double]
            :  .calib_info    [1 x 1 struct]
