+accelerometers.  Actigraph is one of the most common research-grade
+accelerometers.  There is considerable research validating and developing
+algorithms for human activity using ActiLife counts.  Unfortunately, ActiLife
+counts are proprietary and difficult to implement if researchers use different
+accelerometer brands.  The code creates ActiLife counts from raw acceleration
+data for different accelerometer brands.")
