edit data file with text headers with MATLAB

I am trying to edit a text file and overwrite it. The text file has 2 headers lines, thought they don´t correspond to the name of the columns. First column is Time.

#1
double UserProfilesOffice(336, 5)
0  0  0.1  0  0
3540  0  0.1  0  0
3600  0  0.1  0  0
7140  0  0.1  0  0
7200  0  0.1  0  0
10740  0  0.1  0  0
10800  0  0.1  0  0

   .    .        .      .       .  
   .    .        .      .       .     

129540  0.8  0.8  0.3  0.3
129600  0.4  0.8  0  0
133140  0.4  0.8  0  0
133200  0.6  0.8  0.3  0.3
136740  0.6  0.8  0.3  0.3
136800  0.8  0.8  0.3  0.3
140340  0.8  0.8  0.3  0.3

I have to edit only second column data each 7200sec and the next value in second column should be the same, that means multiples of 7200sec then I change it:

129600  0.45  0.8  0  0
133140  0.45  0.8  0  0

Another consideration is that rows are repeated for columns (2,3,4,5) each 86400sec. Then, the program should assign 86400/7200=12 Parameters. I tried the next:

p1=0; p5=0.2; p9=0.3; p13=0.5; p17=0.5; p21=0.6; p25=0.4; p29=0.3; p33=0.2; p37=0.1; p45=0; p49=0;  % Value of the 12 parameters to assign

fid = fopen('file.txt','r');         %# Open the file
topLines = 3;                        %# Keep 2 headers lines
for ii = 1:topLines-1
    fgets(fid);
data = textscan(fid, '%d %f %f %f %f\n','HeaderLines',2);      % Read the data
fclose(fid);                       %# Close the file

fid = fopen('file.txt','w');  %# Open the file
fprintf(fid,'%s',topLines);         %# Print the top lines
for i = 1:size(data)             %# Loop over the rows of data
    if ((7200 * round(double(data{1}(i)))/7200) == (data{1}(i))) && ((data{1}(i))<=86400)      %To determine if (data{1}(i) is a multiple of 7200 and it is in weekdays
    for ii=1:4:49
    fprintf(fid,'%d %.1f %.1f %.1f %.1f %.1f\n',data{1}(ii),p(i),data{3}(ii),data{4}(ii),data{5}(ii));            %# Print data i
    fprintf(fid,'%d %.1f %.1f %.1f %.1f %.1f\n',data{1}(ii+1),p(i),data{3}(ii+1),data{4}(ii+1),data{5}(ii+1));            %# Print data i+1
    end        
    else if ((7200 * round(double(data{1}(i)))/7200) == (data{1}(i))) && ((data{1}(i))<=172800)     
         for ii=50:4:98
         fprintf(fid,'%d %.1f %.1f %.1f %.1f %.1f\n',data{1}(ii),p(i),data{3}(ii),data{4}(ii),data{5}(ii));

         end
         else if ((7200 * round(double(data{1}(i)))/7200) == (data{1}(i))) && ((data{1}(i))<=259200)     
              for ii=100:4:147
              fprintf(fid,'%d %.1f %.1f %.1f %.1f %.1f\n',data{1}(ii),p(i),data{3}(ii),data{4}(ii),data{5}(ii));

                   fprintf(fid,'%d %.1f %.1f %.1f %.1f %.1f\n',data{1}(ii+1),p(i),data{3}(ii+1),data{4}(ii+1),data{5}(ii+1)); 
                   end
                   else if ((7200 * round(double(data{1}(i)))/7200) == (data{1}(i))) && ((data{1}(i))<=432000)  
                        for ii=197:4:245

fclose(fid);                       %# Close the file
