Hello，I tried out a demo run,but failed with the error as following:
at first,I run the humann2 and give the path about Diamond ,it shows CRITICAL ERROR: Error executing: , Error message returned from diamond :, Error: Database was built with an older version of Diamond and is incompatible.
then I installed the latest Diamond ,diamond-2.0.4,and shows the same error
and the diamond help run successed ,the diamond test cases passed.
Any advice is highly appreciated!
