Question Posted 07/11/17:
Dear expert,
Now I have the RID and PTID of the downloaded subjects, and also get the forms of 'CDR.csv' and 'MMSE.csv'. I used the RID to find the corresponding CDGLOBAL values in CDR.csv and the corresponding MMSCORE values in MMSE.csv, but the length of returned values are greater than the length of the downloaded subjects. Could you tell me how to get the CDRGLOBAL and MMSCORE of specific subjects?
