+# DATA & FILE OVERVIEW
+
+## Data File Description: 
+The data of this project comes with one datafile called "linkedData21.csv" this file includes all data needed to recreate the correlation matrix in the manuscript. It containes only complete sets (i.e., only people with both, wearables and observational data). 
+
+## Data File: linkedData.csv
+
+### data
+
+- linkedData.csv : Contains behavioral observations, normalized 24 hrs data and MAD data information. 
+
+The MAD data is calculated over 5sec intervals and this forms the basis of the following derivatives:
+SD
+Median
+Qant 
+Frag
+Rel
+
+The 24hrs data was cleaned of time intervals that the watch was not in use (not on patient wrist but recording while being charged or being with the research team).
+
+The 24 hrs data and the behavioral observations are normalized to 30 min. See more details in attributes list. 
+

+# METHODOLOGICAL INFORMATION
+
+Hardware used: Samsung Wearable, Gear Fit 2 Pro
+Software used: WEARDA https://research-software-directory.org/software/wearda
+Note on wearable data collection: we have different timelines per patient, some participated 4 days for 8 hrs each day, others missed hours due to changing sleep cycles or leaving the building to visit family or a doctor's appointment. The data got was normalized to 30 min intervals to make up for those difference.
+The MEDLO observation schema was used for the behavioral observations.
