This is a start
function cssm( folder_spec, file )
03:05:00 .000 065.501 01** 4864 0086 0074 +19 03:06:00 .000 065.501 01** 4862 0095 0074 +19 03:07:00 R- .026 065.501 01** 4862 0105 0074 +19 03:08:00 R- .180 065.504 01** 4864 0105 0074 +19
sad = dir( fullfile( folder_spec, file ) );
for sa = transpose( sad )
fid = fopen( fullfile( folder_spec, sa.name ), 'r' );
cac = textscan( fid, '%8c%2c%4f%7f%4c%4u%4u%4u+%2u' ...
, 'Delimiter', ' ', 'Whitespace', '' );
fclose( fid );
end
end
Try:
  • set break point at first line
  • run
cssm( 'c:\your_path\2011\', '*.dat' )
  • experiment in break mode with the actual data
  • add working lines of code to the function
  • save and restart function when it becomes messy

I downloaded your file and renamed it to "ReadSoniData_2.m" and I changed the name of the function to "ReadSoniData_2". Then I run
>> clear all
>> cac = ReadSoniData_2( 'h:\m\cssm', '11-02-2011.dat' );
>> plot( cac{3})
It worked without problems. The value of the peak is 60 plus.

Next step, try:
>> dbstop ReadSoniData 2
>> cac = ReadSoniData( 'h:\m\cssm', '11-02-2011.dat' );
However, if you didn't watch Doug's video you might need to do that now. Then step through the code.
.
The data file, '11-02-2011.dat', shall be in your folder, 'C:\matlab7\work\org'.
You could add an assert to the file after "sad = dir(..."
sad = dir( fullfile( folder_spec, file ) );
assert( not( isempty( sad ) ) ...
, 'ReadSoniData:NoFileFound' ...
, 'Cannot find files matching "%s"' ...
, fullfile( folder_spec, file ) )

Hint: In the for-loop you need to assign the result, which you want to keep to an appropriate variable and make that new variable the output argument.
