==Multiple Sessions==
Once a run has ended, BCI2000 goes into suspended state.
Further runs will be added to the session when you click '''Resume'''.

When starting the next session, don't forget to increment the ''SessionNumber'' parameter on the ''Storage'' tab. Otherwise, new runs will be added to the previous session's directory. Still, as a safety net, BCI2000 will never overwrite existing data files but increment the largest run number that exists in a session directory. Moreover, it documents date and time in the ''StorageTime'' parameter. This allows to later associate data files with multiple sessions by their time and date, even if the ''SessionNumber'' parameter has not been increased.
