i'm attempting to save data to an ascii text file. Matlab will create the txt file and inserts some header:

"MATLAB 5.0 MAT-file, Platform: PCWIN, Created on: Fri Jul 23 15:31:42 2010"

and then begins to write my data, the only problem is that i get the following error because of this header:

"Number of columns on line 2 of ASCII file C:\Program Files\MATLAB704\work\Peckat\2010_07_\data153141.txt
must be the same as previous lines."

how do i stop it from making the header or, adjust the columns. completely lost as to what i should do as a solution to this problem.

That is a binary MAT-file, NOT an ASCII text file.

You probably forgot to include the -ascii flag in your call to SAVE. See
HELP SAVE for more information on this flag.

doc save

Particularly read the part about -ASCII. The header is included only in
binary files.
