I have up to ten thousand txt data files with the file names: data_1, data_2, data_5, ... data_10,000.

I am trying to use the following program to read these data:

for i = 1:2000;
File = ['data_' num2str(i) '.txt'];
[X Y Z] = textread(File, '%f %f %f', 'headerlines', 1);
....
end;

The problem is that I have some files missing, such as data_3.txt, and data_4.txt. How can I get around this? Is there a Matlab function like 'isnan' to tell whether a file is available or not?

Thank you.
