generate_condition Leads to Conversion from Struct to Double Error

Hello,

I have been seeking support on generate_condition function and I could not find much online.
I require using the function because I aim to randomly select some stimuli from a file and load them into a condition file using the attached script.
The condition file generated using the function leads to a Conversion from Struct to Double is Not Possible error.
I could not determine if I was misusing the function or if it was outdated, any help or advice on the issue?

Thank you!

I think you could figure out the cause if you opened and looked at the generated conditions file. generate_condition() does not work perfectly, but I have no intention to do anything about it. It is not part of NIMH ML and will not be included in the future versions.

If you want a flexible way to select stimuli, see the userloop function.
