Show certain value in Cell array

Hi. I have the following code which only opens and reads files depending on the file size then the variable output for each file is done in same cell array;

files = dir('D:\MLS_2\2008\v03');
% Loop for each file
for i = 1:length(files)
    if files(i).bytes > 50000
       filename =  files(i).name;
       % display names that are read
       disp(filename)

         % Open files with data
         file_data = H5F.open(filename,'H5F_ACC_RDONLY','H5P_DEFAULT');
         % Data field for data wanted   
         DATAFIELD_NAME = 'HDFEOS/SWATHS/O3 column-GEOS5/Data Fields/L2gpValue';    
         data_id = H5D.open(file_data,DATAFIELD_NAME);
         % Time component
         TIME_NAME='HDFEOS/SWATHS/O3 column-GEOS5/Geolocation Fields/Time';
         time_id = H5D.open(file_data,TIME_NAME);
         % Variables wanted
         data1{i} =H5D.read (data_id,'H5T_NATIVE_DOUBLE', 'H5S_ALL', 'H5S_ALL', ...
              'H5P_DEFAULT');
         time =H5D.read(time_id,'H5T_NATIVE_DOUBLE', 'H5S_ALL', 'H5S_ALL',...
              'H5P_DEFAULT');
         time1lvl{i} =datestr(datevec(datenum(1993,1,1,0,0,0)+time(1)/86400));

      end
  end

Some of the variable output looks like this[228.069580078125;226.937240600586;228.856262207031]. How do I only display the left most value in the cell array.

I'm not sure which variable you're talking about, but if [228.069580078125;226.937240600586;228.856262207031] is the contents of some particular cell you're looking at, let's call it thisCell, then to print it out to the command window you'd do

thisCell =  ..... whatever ......
thisCellContents = cell2mat(thisCell); % Convert contents into column vector of N doubles.
fprintf('The first number = %f\n', thisCellContents(1));

Sorry. I should I have said that it is for the data1 variable.
