Question Posted 09/29/16:
Pls note: I asked the same question a week ago, since no response yet, just put it again:
Dear Experts, my understanding is that, for ADNI2 subjects, each should have a few tests (in different times) and be recorded in clinical data. However, when I check the diagnostic summary file DXSUM_PDXCONV (and others such as ARM), there is only one row for each unique id number (that then might mean one collection only for each subject). SO the question is: how could I find the data for all the collections for a particular subject? Thank you very much for your help.

Please use RID as the subject unique identifier. DXSUM_PDXCONV includes all visits for each subject.
