To access the spike thresholds using Matlab do the following:

// open file
>> file = datastrm('8channelMCDfile.mcd')

// check which field contains the spike data
>> x = getfield(file,'StreamNames')
x = 
    'Spikes 1'
    'Filtered Data 1'


// retriev spike info (which is the first field in this example)
>> SpikeInfo = getfield(file,'StreamInfo',{1})

// check the field
>> SpikeInfo{1}
ans = 
      StreamName: 'Spikes 1'
        DataType: 'spikes'
      PreTrigger: 1.0000e-003
     PostTrigger: 0.0020
        DeadTime: 0.0020
           Level: [1x8 double]
           Slope: [1 1 1 1 1 1 1 1]
    ChannelNames: {1x8 cell}

// access threshold levels of all channels
>> SpikeInfo{1}.Level

ans =
  1.0e-003 *
  Columns 1 through 8 
   -0.1200   -0.1200   -0.1200   -0.1200   -0.1200   -0.1200   -0.1200   -0.1200


//access the associated channel names
>> spikeinfo{1}.ChannelNames
ans = 
  Columns 1 through 8
    '14'    '15'    '16'    '17'    '28'    '38'    '45'    '48'
