I am seeking assistance in accessing the 56-rhesus-monkey MRI dataset archived by Prof. Amaral's group at UC Davis. The compressed file requires an access password that was not provided with the dataset documentation.

Despite contacting the designated administrator (emails sent on [dates]), I have not received a response. Could you please:

1. 
   

   Confirm the current data custodian?

   
   
   
2. 
   

   Advise on proper access protocols?

   
   
   

This dataset is critical for our comparative neurobiology studies. Any guidance would be greatly appreciated.
