Hello All,

I have some data in a file of which some comes under Log Peak-Valley Data whereas the other comes in Log Timed data. I want to read the data only from Log Peak-Valley data and ignore the one from Log Timed data and other paramters also as given below.

I have got the code for extracting all the numbers but my problem is it comes frmo Log Peak-Valley data as well as from Log Timed data.
Can anyone suggest me how to get rid of the Log Timed data ?

I am using the code as shown below. I am not sure what string data I need to use

while feof(fid) == 0
tline = fgetl(fid);
line_tokens = regexp(tline, '\s+', 'split');
[rows columns] = size(line_tokens);
if columns == 6
coordinates(x,1) = num2cell(str2double(line_tokens(1,1)));
coordinates(x,2) = num2cell(str2double(line_tokens(1,2)));
x = x + 1;
end


The File which I am using is as follows :

if strmatch('Log Timed', tline)
while ischar(tline) & ~isempty(tline)
tline = fgetl(fid);
end
end

After which tline will be numeric if you hit end of file and will be the
empty string otherwise.
