Hi Rajan

These tutorials were created based on an older release of OPAL. Therefore, the input file needs some modifications. I will proceed to update them so that they will be on the wiki page as soon as possible.

You have to apply the change that Weizhuang suggest. Anyway, I'm sending you an updated version that runs satisfactorily in opal.

Best regards

Hi Rajan,

In version 2022, the 'RING' becomes a key word used by the program. 

You can change the name of the line from 'RING' to something else and it should be fine.

Best,

Weizhuang
