MATLAB: Save output sequence of files

loopoutputsequence

Hi! I have a question about how can I save a loop outputs. I want to write the output values of a large series of files on a separate line on text.txt. The problem is it only works with the first one, but it doesn't work with the rest. Is there something wrong?
myPath = 'C:\EX\'; 
a= dir (fullfile(myPath,'*.DIM')); 
fileNames = { a.name };
% Rename files
for k = 1:length(fileNames)
     newFileName = [fileNames{k}(1:2) fileNames{k}(4:6) '.txt']; 
     movefile([myPath fileNames{k}], [myPath newFileName]);
end
 filePattern=fullfile( myPath,'*.txt');
 txtFiles= dir(filePattern);    
   for k = 1:length(txtFiles)
    baseFileName=txtFiles(k).name;
    fullFileName= fullfile(myPath,baseFileName);
    fid=fopen(fullFileName, 'r');
    for i = 1:18
        m{i} = fgetl(fid);
    end
    result2 = m{18};
    result2b= result2([12:19]);
    fid=fopen(fullFileName, 'r');
    for i = 1:30
    m{i} = fgetl(fid);
    end
    result3 = m{30};
    result3b= result3([12:19]);
    fid=fopen(fullFileName, 'r');
    for i = 1:31
    m{i} = fgetl(fid);
    end
    result4 = m{31};
    result4b= result4([12:20]);
    fid=fopen(fullFileName, 'r');
    for i = 1:19
    m{i} = fgetl(fid);
    end
    result5 = m{19};
    result5b= result5([12:20]);
   text= {baseFileName, result2b, result3b, result4b, result5b};
    final= [Fields'; text];
       end
I've read about fprint command and I've tried but it doesn't work at all. Really thanks in advance!
EDIT:
I added a screenshoot about my variables. Is it possible because of the txtFiles is wrong?

Best Answer

 filePattern = fullfile( myPath,'*.txt');
 txtFiles = dir(filePattern);    
 output = cell(length(txtFiles), 5);
 for k = 1:length(txtFiles)
    baseFileName = txtFiles(k).name
    fullFileName = fullfile(myPath, baseFileName );
    fileData = fileread(fullFileName);
    fileCell = regexp(fileData, '\n', 'split');
    result2 = m{18};
    result2b= result2([12:19]);
    result3 = m{30};
    result3b= result3([12:19]);
    result4 = m{31};
    result4b= result4([12:20]);
    result5 = m{19};
    result5b= result5([12:20]);
    output(k, :) = {baseFileName, result2b, result3b, result4b, result5b};
  end
