problem to edit a text file

Dear all,
I am having some difficulties to edit my text file. I have an input file which I need to modify certain lines (11844 lines) in each iteration. The input file is a mixture of text, numbers. the numbers are the coordinates of my object in 3D space. So I open the file and rewrite the new coordinates but when it writes it down it pushes the have of previous coordinates and just replace half of it with my new data. So at the end I have correctly started place for my new points but then at the end I see some residue of the previous coordinates.
find_line = '*Node';
InputFID=fopen([file,'.inp'],'r+');
j = 0; count=0;
while j==0
count = count+1;
tline = fgetl(InputFID);
j = strcmp(tline, find_line);
end
n = 1;
format = ' %5.0f, %.4f, %.4f, %.4f \n';
fseek(InputFID,0, 'cof');
for n = 1:size(newdata,1)
m = [newdata(n,1), newdata(n,2), newdata(n,3), newdata(n,4)];
fprintf(InputFID,format,m);
end
fclose(InputFID);
I will appreciate any idea, Thanks Sareh

My first idea is
str = fileread( [file,'.inp'] );
str = regexprep( str, ...
and hope there are keywords in the file to locate the coordinates of interest
