Below is what the command window shows!
>> parseRunCaseFile
Not enough input arguments.
Error in parseRunCaseFile (line 5)
fileID = fopen(filename);

That means your are trying to run function without giving input filename. You should run the function in script file or command window with passing input variable filename as
>> filename = 'give your complete file full path';
>> [ rc ] = parseRunCaseFile(filename)
