Hi Justin, re: > I gather the Scheduler and CYCLE work independently. Yes. The scheduler runs commands. CYCLE= is a keyword that is pertinent to the IMGDISP command. re: > How would I incorporate both into the command line or would I need to? > > SKE 04/04 0 999999 45:00 "IMGDISP PUB/MTGLOB04I2 1 ALL=1 10 LATLON=14 -128 > MAG=2 SF=YES REFRESH='EG GRA=(GRA);MAP FILE=OUTVHPOL GRA=(GRA)’; TERM L ON First, it appears that elements in the PUB/MTGLOB04I2 dataset update every hour: IMGLIST PUB/MTGLOB04I2.ALL Image file directory listing for:PUB/MTGLOB04I2 Pos Satellite/ Date Time Center Band(s) sensor Lat Lon --- ------------- ------------ -------- ---- ---- ------------ 1 MTSAT-2 3 APR 15093 10:32:00 0 -145 2 2 MTSAT-2 3 APR 15093 11:32:00 0 -145 2 3 MTSAT-2 3 APR 15093 12:32:00 0 -145 2 4 MTSAT-2 3 APR 15093 13:32:00 0 -145 2 5 MTSAT-2 3 APR 15093 14:32:00 0 -145 2 6 MTSAT-2 3 APR 15093 15:32:00 0 -145 2 7 MTSAT-2 3 APR 15093 16:32:00 0 -145 2 8 MTSAT-2 3 APR 15093 17:32:00 0 -145 2 9 MTSAT-2 3 APR 15093 18:32:00 0 -145 2 10 MTSAT-2 3 APR 15093 19:32:00 0 -145 2 11 MTSAT-2 3 APR 15093 20:32:00 0 -145 2 12 MTSAT-2 1 APR 15091 21:32:00 0 -145 2 13 MTSAT-2 1 APR 15091 22:32:00 0 -145 2 14 MTSAT-2 1 APR 15091 23:32:00 0 -145 2 15 MTSAT-2 2 APR 15092 00:32:00 0 -145 2 16 MTSAT-2 2 APR 15092 01:32:00 0 -145 2 17 MTSAT-2 2 APR 15092 02:32:00 0 -145 2 18 MTSAT-2 2 APR 15092 03:32:00 0 -145 2 19 MTSAT-2 2 APR 15092 04:32:00 0 -145 2 20 MTSAT-2 2 APR 15092 05:32:00 0 -145 2 21 MTSAT-2 2 APR 15092 06:32:00 0 -145 2 22 MTSAT-2 2 APR 15092 07:32:00 0 -145 2 23 MTSAT-2 2 APR 15092 08:32:00 0 -145 2 24 MTSAT-2 2 APR 15092 09:32:00 0 -145 2 25 MTSAT-2 2 APR 15092 10:32:00 0 -145 2 26 MTSAT-2 2 APR 15092 11:32:00 0 -145 2 27 MTSAT-2 2 APR 15092 12:32:00 0 -145 2 28 MTSAT-2 2 APR 15092 13:32:00 0 -145 2 29 MTSAT-2 2 APR 15092 14:32:00 0 -145 2 30 MTSAT-2 2 APR 15092 15:32:00 0 -145 2 31 MTSAT-2 2 APR 15092 16:32:00 0 -145 2 32 MTSAT-2 2 APR 15092 17:32:00 0 -145 2 33 MTSAT-2 2 APR 15092 18:32:00 0 -145 2 34 MTSAT-2 2 APR 15092 19:32:00 0 -145 2 35 MTSAT-2 2 APR 15092 20:32:00 0 -145 2 36 MTSAT-2 2 APR 15092 21:32:00 0 -145 2 37 MTSAT-2 2 APR 15092 22:32:00 0 -145 2 38 MTSAT-2 2 APR 15092 23:32:00 0 -145 2 39 MTSAT-2 3 APR 15093 00:32:00 0 -145 2 40 MTSAT-2 3 APR 15093 01:32:00 0 -145 2 41 MTSAT-2 3 APR 15093 02:32:00 0 -145 2 42 MTSAT-2 3 APR 15093 03:32:00 0 -145 2 43 MTSAT-2 3 APR 15093 04:32:00 0 -145 2 44 MTSAT-2 3 APR 15093 05:32:00 0 -145 2 45 MTSAT-2 3 APR 15093 06:32:00 0 -145 2 46 MTSAT-2 3 APR 15093 07:32:00 0 -145 2 47 MTSAT-2 3 APR 15093 08:32:00 0 -145 2 48 MTSAT-2 3 APR 15093 09:32:00 0 -145 2 IMGLIST: done Give this, I would set the interval for running IMGDISP at one hour, not 45 minutes. The next thing you may want to try to ascertain is when the new image is actually made available in the dataset. Note that this in not likely to be the image time; you would have to keep an eye on when a new image shows up and add a few minutes to the minute and then setup the time in your SKE command. Now, how to incorporate CYCLE into IMGDISP command you want to run from a scheduler entry. This should work: SKE 04/04 0 999999 1:00 "IMGDISP PUB/MTGLOB04I2 CYCLE=1 1 10 00:45 LATLON=14 -128 MAG=2 SF=YES EU=IRLONG REFRESH='EG GRA=(GRA);MAP FILE=OUTVHPOL GRA=(GRA)' But, it seems more likely that what you want is: SKE 04/04 0 999999 1:00 "IMGDISP PUB/MTGLOB04I2 SEQ=1 10 LATLON=14 -128 MAG=2 SF=YES EU=IRLONG REFRESH='EG GRA=(GRA);MAP FILE=OUTVHPOL GRA=(GRA)' The IMGDISP invocation using SEQ= should update the frame with the oldest image with the new image. It will not update any frame is the newest image is already displayed, and because of this, you could run the scheduler command more frequently than once per hour if the time that new images are added to the dataset is not consistent.
