$ concert edit new-session
At the top of the file, you can see a string enclosed in three ". This should changed to something descriptive as it will
be shown each time you start the session.
Adding devices
To create a device suited for your experiment you have to import it first. Concert uses the following packaging scheme
to separate device classes and device implementations: concert.devices.[class].[implementation].
Thus if you want to create a dummy ring from the storage ring class, you would add this line to your session:
from concert.devices.storagerings.dummy import StorageRing
Once imported, you can create the device and give it a name that will be accessible from the command line shell:
from concert.devices.motors.dummy import LinearMotor
ring = StorageRing()
motor = LinearMotor()
Importing other sessions
To specify experiments that share a common set of devices, you can define a base session and import it from each
sub-session:
from base import *
Now everything that was defined will be present when you start up the new session.
