Queries regarding CNP preprocessed dataset

Hi, I’m Chaitree, and I’m a MSc Cognitive Science student at the Indian
Institute of Technology Delhi, India. I am using the CNP preprocessed
data mentioned in the ‘Preprocessed Consortium for Neuropsychiatric
Phenomics dataset’ (Preprocessed Consortium for Neuropsychiatric Phenomics dataset - PMC) for my masters project.

I had few queries regarding the dataset for stop signal task. Is there anyone who is using this dataset for stop signal task ? I would really appreciate your help in resolving my queries. Kindly let me know if someone can help me with it.

Thank you.

Regards,
Chaitree
