  • Each time the MSB starts, a new session is started. Files on the MSB increment with the pattern
    • log.uwar
    • log-0001.uwar
    • log-0002.uwar
    • ....


  • Downloaded data are stored in separate subdirectories for each subject, named part_00, part_01, etc., per MSB power-cycle session
    • Each part should be downloaded and processed separately. Use the script msb.get.data to download all the parts in one step.
  • Once downloaded, use the R script read.msb.files to generate csv files.
  • To remove duplicate records with duplicate seconds timestamps from the class.csv file, use the perl script msb_remdupes.pl script.

The csv files can be related by timestamps (i.e., phone_log and class by the date field).
