- 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.
- There may be records with duplicate timestamps. To remove duplicate records 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).
