The Rush Alzheimer's Disease Center (RADC) offers various data on Religious Orders Study/Memory and Aging Project (ROSMAP) participants. Biospecimens and limited data sets are by approved request, and omics data can be downloaded through the AMP-AD Knowledge Portal with a Synapse account and data use agreement. These two sources identify ROSMAP participants using different ID formats.

Note: Projids are commonly auto-formatted as numbers, such as by Excel, which removes leading zeroes. A projid with fewer than eight digits should be understood as having leading zeroes reapplied until length equals exactly eight; for example, a projid written as 1234567 is the same as the projid 01234567.

To match the participants across the two ID formats, use the ROSMAP_clinical.csv metadata spreadsheet on Synapse. As with downloading omics, access to this metadata file requires a Synapse account.
