Our group is interested in only obtaining a subset of the variables specified in the file *mesa-commercial-use-data-dictionary-0.4.0.commercial-variables.csv *. For instance extracting only sdnnidx_fn5, svspo25, and bpmavg5 for each patient. In the csv file, it specifies folder location. However, these folders do not exist in the database. How do we get access to these folder or any of these variables listed in the csv file?
Thanks in advance.
