Hi everyone. Can anyone help us to split the data into many files. The example data is attached.
This is how the data look like..
Lat: 6.4931, Lon: 99.6067, Parameter: z(m) <--This is the start line
Depth (m): 22.45
Constituents included: m2 s2 k1 o1
Time start: 00:00, 1. 1.1993
Time step (min): 60.00
Time Series length (hours):236664
01-Jan-1993 00:00:00 -0.0946
01-Jan-1993 01:00:00 -0.3369
01-Jan-1993 02:00:00 -0.5110
... More Data
31-Dec-1993 23:59:59 -1.1673 <-- This is the last line
Lat: 6.3933, Lon: 99.6067, Parameter: z(m) <--- Another start line for different coordinate
Depth (m): 30.74
Constituents included: m2 s2 k1 o1
Time start: 00:00, 1. 1.1993
Time step (min): 60.00
Time Series length (hours):236664
01-Jan-1993 00:00:00 -0.1017
01-Jan-1993 01:00:00 -0.3324
01-Jan-1993 02:00:00 -0.4965
... More Data
31-Dec-1993 23:59:59 -1.1284 <--Another last line

The code below assumes each file ends with an empty line. You could also search for 'Lat:' instead to determine the beginning of a new file.
data=readfile('https://www.mathworks.com/matlabcentral/answers/uploaded_files/351353/Example.txt');
lastlineoffile=find(cellfun('isempty',data));
lastlineoffile=[0;unique([lastlineoffile;numel(data)])];%add last line just to make sure
for n=1:(numel(lastlineoffile)-1)
currentfile=data((lastlineoffile(n)+1):lastlineoffile(n+1));
fid=fopen(sprintf('aa__file%03d.txt',n),'w');
fprintf(fid,'%s\n',currentfile{:});
fclose(fid);
end
