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 note that the subject identifier is in the RID column. The ID column is a unique record identifier. Please see the Interpreting Data section of the FAQ page for more tips. Here is the link: http://adni.loni.usc.edu/data-samples/data-faq/
