+# INSTRUCTIONS:
+# Run this script (bash deduplicate_project_exclusions.sh) which will go through all the projects and transform the exclusion tag object into a string,
+# containing just the exclusion tag id. For example: exclusionTag: { "id": "neurosynth_exclude_exclusion", label: "Exclude", isExclusionTag: true, isAssignable: true } -> exclusionTag: "neurosynth_exclude_exclusion"
+# This script will:
+# 1. Create a reusable PostgreSQL function for the transformation
+# 2. Validate the transformation by checking that the number of stub studies and the exclusion tag id are the same for each project
+# 3. If the validation passes, update the projects with the transformed data WHEN THE USER CONFIRMS "yes"
+# 4. Clean up the function
