We have been using the NKI Rockland data from the FCONN-1000 study on NITRC for some time. We would like to update our studies to use the most recent release of the NKI Rockland study that is available via COINS. We are having difficulty matching up the subject numbers between the releases. Is there a document that describes how to convert between the codes or provides a table of corresponding subjects ID's?

From the FCONN-1000, we have ID's of the form:
Subject: 3895064
Session: MR_3895064_743f

From COINS, we are finding ID's of the form:
Anonymized ID: A00033735

Thank you,
Bennett

Hi Bennett, 
Did you ever receive a response to your question? 
I'm having the same exact problem, and would greatly appreciate any information on the matter. 
Thanks,
