SYNC

Synchronizes loops running in multiple briefing windows.


Format

SYNC syncfile


Parameter

syncfile

file containing synchronization configuration


Remarks

Use the SYNC command to create briefing windows displaying synchronized frame loops. To run the command, you must first create a text file containing the synchronization configuration. The first line in the configuration file defines the dwell rate for each frame. Subsequent lines define the frame sequence for each briefing window, one line of frame numbers for each window. A maximum of nine briefing windows (windows 0-8) is allowed in the file.

The sample file shown below sets up two briefing windows, 0 and 1. Window 0 displays frames 1-4. Window 1 displays frames 5-8. The frames loop as fast as possible with a delay on the first frame.

4 1 1 1
1 2 3 4
5 6 7 8

If you want briefing window 1 to loop at half the speed of window 0, you could create a file like the one below. Frames 1-4 will loop twice as fast as frames 5-8.

1 1 1 1 1 1 1 1
1 2 3 4 1 2 3 4
5 5 6 6 7 7 8 8

You can include comments in the configuration file by starting a line with the pound sign (#). Comments may appear anywhere in the file but must be on a separate line. Blank lines are not allowed in the configuration file.

Because the SYNC command creates briefing windows, you should close any existing briefing windows before running the command. If any briefing windows are present, duplicate windows may be created causing faulty synchronization or other conflicts.

You may run out of memory trying to run SYNC. If this happens, try making your frames smaller, or use fewer briefing windows. If your McIDAS-X briefing windows appear with private color maps, they may not all be displayed with the correct colors when they are looping. If this happens, restart your McIDAS-X session with fewer image and graphics colors.


Example

SYNC SYNC1.TXT

This entry creates briefing windows and synchronously displays frames in them using the dwell rates and frame sequences specified in the file SYNC1.TXT.
