Hi, I want to analyze the raw mass spectra for a specific subset of the cohort in syn17015099. How do I map these files to patients? Thanks, Juan

Hi Juan, To map these results to patients, you'll need to join the results to the information provided in the individual (ROSMAP_clinical.csv) and biospecimen metadata files. The metadata files for the ROSMAP study are listed in the AD Knowledge Portal [here](https://adknowledgeportal.synapse.org/Explore/Studies/DetailsPage/StudyData?Study=syn3219045); you can use the search and filter capabilities supported by the portal to find the specific metadata files that you need. For further information about working with metadata files, please refer to our help documentation [here](https://help.adknowledgeportal.org/apd/About-Metadata.2241626149.html). Best, Jessica
