Dear experts, 

I have matched MR sessions and ADRC clinical data entries according to the oasis data matchup.py file, and according to the consensus that both num_days_before and num_days_after are 365, ADRC data is effective. Some MR sessions do not match the ADRC. For example, one of MR sessions is OAS30003_MR_d0558, OAS30003_UDSb4_d0000 and OAS30003_UDSb4_d1083 exist in the ADRC. The difference between 558 and 0 and the difference between 558 and 1083 both exceed 365, so the MR session does not match the ADRC data. In general, how to deal with this situation, should we relax the limit of days and let each MR session match the ADRC data or directly delete the MR sessions that do not match the ADRC data?

Thank you in advance for your help. 

Best regards,

Ji Di
