I'm not really sure what is unclear about that message or what we could possibly do to assist with it.
The file you are telling it to open does not exist. Either you put the filename together incorrectly or the file simply isn't there.

I am confused because both of the possibilities (that u told) are not there. Spellings are correct and even file textread is also present in my code. I am attaching "textread" file with this comment for your reference. Please have a look.

Never mind that, as the content of the file clearly states, it is copyrighted so you're not allowed to post it on the web.
The file that does not exist is the one you're trying to open with textread. Of course, textread exists, it's part of matlab.

@harpreet: HAve you seen the copyright notice in the code you have posted? Please remove this code from the forum.

I've removed textread.txt, although I would point out that it was named textread.txt. It was not an m-file, but a .txt file. That MAY have been part of the problem.

What exactly are "function folders" ? How is this script run?

The file you want to read does not exist. Set a breakpoint and check this:
exist(fullfile(db_dir, DB, file_ground_truth), 'file')

You might try textscan(). textread() has been deprecated. But the real problem is that your filename is not exactly what you think it should be. Here, put this code instead of the call to textread()
fullFileName = fullfile(db_dir, DB, file_ground_truth)
if ~exist(fullFileName, 'file')
errorMessage = sprintf('Error: file does not exist:\n%s\nPlease check the spelling very carefully.', fullFileName);
uiwait(warndlg(errorMessage));
else
data = textscan(....................

Either put that file in that folder, or change the file name to one that DOES exist.
