Data management 

The Data tab view has three panels: 1) Raw data file list with original downloaded 
data files, 2) Worksheets list with each of the epoch-sampled worksheets that have 
been created, and 3) detail view of the data file or worksheet that is selected. 

 

 

Raw files  

Raw files contain the STARwatch sensor measurements at the full sampling rates 
that were selected during recording. The sampling rates may vary between 
channels, so the raw files contain data streams at variable sampling rates. Each time 
a download from a device is completed a new Raw file is created, and cannot be 
modified after it has been created. 

The fields in the raw files include the following:
