Hi, I have several files for a different points. The file name is a number like this:
C:\Users\cborba\Documents\Tides\10513.txt
I need get the latitude of each one(line 4 from the header) and read the file without the header (starting from line 12). How can I do this?
Thanks

fid = fopen(C:\Users\cborba\Documents\Tides\10513.txt');
line1 = fgetl(fid);
res=[];
while ischar(line1)
res{end+1,1} =line1
line1 = fgetl(fid);
end
fclose(fid);
latitude=regexpi(res{4},'(?<=LATITUDE).+','match')
data=res(12:end)

Thaks Azzi for your help. Could you help a little more? I did exactly that you said and I get a variable data that's looks like: '17/11/1977 04:00,326,' and a variable latitude that's looks like: 01º,30'.0,S. How can I split the variable data into 2 others variables like date (17/11/1977 04:00) and hight (326). And how can I convert the latitude to decimals degree (-1.50)? Thanks a lot

date=cellfun(@(x) x{1},regexp(data,'.{16}','match'),'un',0)
hight=str2double(cellfun(@(x,y) regexp(x,['(?<=' y ').+'],'match'),data,date))

One possibility is to use the Import Tool, available on the Home tab of the Toolstrip of the Command Window. This allows you to specify the exact spreadsheet locations you want to import.
