I went to: https://services.loni.ucla.edu/ida/archive?SubMode=GotoSearch and did a set of searches, then looked at the fields they used; Many of the fields are described, but not used (i.e. there are no instances which have some data in these fields). Doing this shows that the vast majority of the data lies in MRI/PET, rather than anything else (MRA, etc.) HTH, Matt Alan Ruttenberg wrote: > Ok.
