Request for introducing file formats

[vxfla]

It's a wonderful work and as a beginner I appreciate for being able to learn a lot from it.
However, I have no access to the DIHARD datasets, so I want to run the recipes on AMI dataset.
When doing so, I'm confused about the file formats ,like .lab/ .uem and path structures.
May I borrow you some time to explain how to prepare the wav files so that I can run the recipe on my own datasets.
