ok... let's create a simple example
(note: look at it using the ORIGINAL VIEW to see the propper formatting)

% foo.txt
1 2 3 4 5
10 11 12 13 14 15
% end of foo.txt

one of the solutions

fnam='foo.txt';
s=textread(fnam,'%s','delimiter','\n','whitespace','');
r=regexprep(s,'\s{4,4}',' 0'); % <- three SPACEs + '0'
r=cat(1,r{:})
%{
% r =
0 0 1 2 3 0 0 4 5 0 0
0 0 10 11 12 0 0 13 14 0 15
%}

THanks for all the help.

I tried what you suggested and it didn't quiet work like i was hoping it would. Due to time constraints i think i'm just going to bite the bullet and do a find replace for the files so i can start processing them. Thanks again for all the help
