HC query issues

QPN

TSV (April 12, 2024): - num. healthy controls: 67 - num. PD patients: 205 - (rest are PPS, etc.)

Query tool / API: - num HC: 294/303 - num PD patients: 276/303

Q's about current query template

• Should having a phenotypic session not be optional?
• Subject group (HC) is currently modeled at the session level but maybe should be instead a subject-level property, or at least standardized across sessions for a subject
  • can subject group change across timepoints (?)
