Data extraction from a text file.

I have the following data:

   74
  : 69
  : 65
  : 50 
  : 39
  : 28
  : 19
  : 8

I created the following code to read the data:

fid=fopen('kirby1.txt');
data=textscan(fid,'%f','delimiter',':');

but it turns the ":" into "NAN". Is there a way to read the data without the ":"?

Desire output:

 74
 69
 65
 50 
 39
 28
 19
 8

Thanks for your help.

Does the first line differ from the others?

I guess the NaNs are the non-excisting values before ":".

If all lines have the same format try

    data=textscan(fid,':%f');

--- Cont. ---

This work with R2012a

    fid = fopen( 'cssm.txt' );
    cac = textscan( fid, ':%f' )

where cssm.txt contains

    : 74
    : 69
    : 65
    ...

--- Cont. ---

Or if the first line differs

    function cssm()
        fid = fopen( 'cssm.txt' );
        ca1 = textscan( fid, '%f', 1 )
        ca2 = textscan( fid, ':%f' )
    end

where cssm.txt contains

    74
    : 69
    : 65
    ...

I got the following error:

??? Error using ==> textscan Badly formed format string.

It is difficult for me to guess the reason to the error you see!

You didn't answer my question in my comment on your question.

Kirby, please show your line of code for the textscan()

f = fopen('yourtextfile.txt');
c = textscan(f,'%s');
fclose(f);
out = str2double(c{:}(1:2:end));
