Hi，here is the problem when i using BBopt in my project.
Traceback (most recent call last):
File "I:/intention recognition/MyBBopt/testFile.py", line 167, in <module>

File "I:/intention recognition/MyBBopt/testFile.py", line 81, in run_trial

ValueError: 16 is not in list

i really confused，what's the meaning of 16? it doesn't exist in my project. Could you give me any advice?

@wunanfang I think you probably changed the arguments for one of your parameters without deleting old data generated with those parameters. If you remove your old data, do you still get this problem? Regardless, the newest version of BBopt should now produce a better error message in that situation.
