When you say you ‘nothing appears in the original window’ are you referring to the Edit Pre-burst Temporal Patterns dialogue box? If so and it is empty is the ‘Use default pre-burst patterns’ checkbox ticked? If it isn’t ticked then RORB is expecting you to manually enter in pre-burst temporal patterns and by leaving it empty there are no pre-burst temporal patterns and it would give you that error when you try to run it.
If this isn’t the case would you be able to email me a screenshot of the window so I can take a look? My email is email@example.com.
