Hi, I am stuck up with a simple query wherein I want to check if particular string exits in a given string. i.e. If I am using input image from following file path C:\New Folder\Level1\Image1.tiff Now I want to check if a string "Level1" exists in a given file path name. I want to know only its existence & not its length, position or occurrence. Simply in the form of true or false (o or 1). Can someone please help me with this. Thanks in advance for your help!

Look at these examples, and pick whichever one of the methods suits you best:
s = 'C:\New Folder\Level1\Image1.tiff'
template = 'Level1' % Cases match
foundIt = any(ismember(s, template))
index = strfind(s, template)
foundIt = ~isempty(index)
template = 'level1' % Case mismatch.
index = strfind(s, template)
foundIt = ~isempty(index)
template = 'level1' % Case mismatch.
index = strfind(upper(s), upper(template))
foundIt = ~isempty(index)

Good one! Seems that I am very close to the solution. Just a small issue which I am experiencing. Following is part of my code (Suppose strfind = 'C:\New Folder\Level1\Image1.tiff')
template = 'Level1'; % Cases match
index = strfind(srcFiles, template);
A = ~isempty(index);
if A = 0;
s1x=142; s1y=122; s2x=190; s2y=220;
else template = 'Level2'; % Cases match
index = strfind(srcFiles, template);
A = ~isempty(index); if A = 0
s1x=142; s1y=122; s2x=190; s2y=220; end end
It is giving me an error while checking for A = 0; the error says "Parse error at "=": usage might be invalid MATLAB syntax." Simply I want to use above logic for 8 times to check 8 levels. Am I missing something while checking A = 0?

You want
if A == 0
Notice the double equal sign for checking equality.

And the semicolon at the end of an "if" statement is ignored.
