Collecting data, very specific lines, avoiding unecessay lines in between

Hello All,

I have a .txt file contains 894 lines, now I am interested to collect the line just below the STEP TYPE MEASURED RATE LIMIT RESULT line til end of file. There are 22 steps and I want to collect data from 1 to 22 and then save it in a new .txt file. How can I do it, any idea/comments will be very helpful?

 'TEST     ERROR         SAMPLES      ERROR      ERROR     INTERIM'
 'STEP     TYPE          MEASURED     RATE       LIMIT     RESULT'
 '1        BCS ACK/NACK   2054        0.00000    10.0000   Inside'

 'TEST     ERROR         SAMPLES      ERROR      ERROR     INTERIM'
 'STEP     TYPE          MEASURED     RATE       LIMIT     RESULT'
 '2        BCS ACK/NACK   2054        2.00000    10.0000   Inside'

 'STEP     TYPE          MEASURED     RATE       LIMIT     RESULT'
 '22        BCS ACK/NACK   2054        1.10000    10.0000   Inside'

Just use fopen, fgetl, and fclose. Read the line with fgetl(). Then use strfind(). If you find 'TEST' or 'STEP', ignore that line. Then use textscan to get the data from the "good" line. Use fprintf() to write out the data to the new file.

 clc;
 clear all;
 textFilename = 'Test.txt';
 FiletoOpen=fopen(textFilename,'r');

 s={};
 tline = fgetl(FiletoOpen); 
 while ischar(tline)
    s=[s;tline];
    tline = fgetl(FiletoOpen);
    X=strmatch('STEP',s);

% I dont think last 3 lines is correct, giving me something different. I have already spotted the lines by strmatch ('STEP',s) and now incremeted +1 which is the line I want to read and store but I dont think it's right-any comments?

    for k=1:(X+1)
       Data{k}= textread(textFilename, '%s', 'delimiter', '\n');
    end
  end
