Running ORAC-DR

Once the environment has been configured the oracdr command will be available. Help on the available command line options can be listed by invoking oracdr -h. In its simplest form with no options, the pipeline will launch a logging window and start processing data from observation number 1 until no more data are available. For example²:

% oracdr
Orac says: No UT date supplied, using 19981001
ORAC says: Starting up monoliths...Done
Setting up display infrastructure (display tools will not
be started until necessary)...Done
No observation numbers supplied - starting from obs 1
Checking for next data file: 19981001_dem_0001.sdf....

Note that the default setting is that ORAC-DR will use the current UT date and start looking for observation number 1 in the ORAC_DATA_IN directory. It will wait for a flag file to appear until the timeout period expires (1 hour) or until the pipeline is aborted with CTRL-C. This behaviour is equivalent to running ORAC-DR with the following options:

% oracdr -from 1 -loop flag

In many cases this is the correct behaviour at the telescope. In order to modify the behaviour of ORAC-DR command-line options can be used.
