Estimates the time it will take to run a sequence file. Four command types are assessed for time: Scans, Moves, Counts, and Waits. Scans are assessed using the scan howlong command. Moves are assessed using the overhead for the devices being moved or the overhead provided with the -o option (see below).
The Rate command should be run before running Sequence Howlong if a monitor count is being assessed. If it has not been run when Scan Howlong is run, it will be run automatically before a result is given, unless a scan is in progress, in which case the command will fail.
[filename] is the name of a sequence file in the experiment directory. The filename should contain the full extension .seq.txt.
[-s] indicates that the results should be returned in seconds (the default is hours).
[-o movementOverhead] tells ICE to use the specified overhead as a minimum overhead per point for instrument movement. The overhead is in seconds. If a device is set with a larger overhead, then that overhead will be used.
