Error in mdfimport>mdfread (line 1692)
    datatype=datatypeformat(signalDataType,numberOfBits); %Get signal data type (e.g. 'int8')

Error in mdfimport>mdfload (line 1106)
            [data signalNames]=mdfread(MDFInfo,dataBlock,selectedChannels); % Load specified signals

Error in mdfimport>importdatawithoptions (line 2271)
                mdfload(options.MDFInfo,dataBlock,channelIndices,options.blockDesignation,ws,options.additionalText);

Error in mdfimport>importdata_Callback (line 354)
    importdatawithoptions(options);

Error in gui_mainfcn (line 95)
        feval(varargin{:});
