I'm using textscan to read in formatted data from text files. However the files don't have a set number of lines of data. The textfiles have a set amount of header lines (which I am using the 'headerlines' option in textscan to skip), then there is a random number of data lines. Then after the data lines, there is one more line that isn't formatted data.

I need to know how to use textscan to read in all of the data, and stop after the last line of actual data. I was thinking of using a while loop, and when the end of the data is reached, just end the loop. But if there is something simpler, please let me know.

while i>0
datainfo=textscan(fid, '%s', 5, 'headerlines', 1);
end

I guess i just need an if statement in there determining if I've reached the end of the actual data.

Any help is appreciated,

Thanks.

why do you not simply read the whole file in one shot(?)...
