Extracting number array from mixed-format data.

Hello.

I am trying to extract a array of numbers from a .txt file that has mixed-format data.

With textscan I can find all of the instances of keyword "Total temperatures".

%%Import Safir output file

    FileName="PROOV_666.txt";

%%Read the txt file
      FID = fopen(FileName, 'r');
          if FID == -1
              error('Cannot open file')
          end
      Data = textscan(FID, '%s', 'delimiter', '\n', 'whitespace', ' ' );
      CStr = Data{1};
      fclose(FID);

%%Find string
      Index = strfind(CStr, 'TOTAL TEMPERATURES');
      IndexA = find(not(cellfun('isempty', Index)));

How do I extract array of numbers between the first and second instance of "Total temperatures", then between second third instance and so on. The array of numbers has a fixed number of columns but the number of rows can vary. Also in the .txt file the numbers are delimited by spaces/tab. Here is a example of the .txt file:

TOTAL TEMPERATURES.
--------------------
  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.
     1   20.0     2   20.0     3   20.0     4   20.0     5   20.0
     6   20.0     7   20.0     8   20.0     9   20.0    10   20.0
   ...   ...    ...   ...    ...   ...    ...   ...    ...   ...
 26121   87.8 26122   87.8 26123   87.8 26124   87.8 26125   87.8
 26126   87.8 26127   87.8 26128   87.8 26129   87.8 26130   87.8

 TIME=     60.0000 SECONDS   OR   1 MIN.  0 SEC.
 ===========================================

 CONVERGENCE HAS BEEN OBTAINED.
 =============================
    TIME =    60.00000

 TOTAL TEMPERATURES.
 --------------------
  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.  NODE  TEMP.
     1   20.0     2   20.0     3   20.0     4   20.0     5   20.0
     6   20.0     7   20.0     8   20.0     9   20.0    10   20.0

I would like to create a individual array for each instance - so I could refer to each of then separately later on.
