Model cannot run in current configuration.

Dear Community.
      I'm having this problem in fragstats software and have not been able to solve it, I wonder if there are any recommended strategies to solve it? Below is a detailed description of the problem in log messages. Thank you for your help!

Welcome to Fragstats v4.2 [x64] !

The log indicates that you probably checked the class and landscape levels under the Analysis tab but then did not select any metrics at those levels on the corresponding tabs.

Warning: Units not specified, meters assumed. why?

If the input image header doesn't contain any information on the units, Fragstats assumes meters as this is the safest assumption. It is the user's responsibility to make sure the units are in fact meters since this is what Fragstats requires.
