wxloop.cgi Loop Web-accessible [jpg gif png tiff] files. Choose images by dates or number of images.
Optimization: For speedy looping, set your browser's memory cache to 10 MB or more (20 MB recommended for weather discussions) and set your disk cache to 30-50 MB. Recommendations: for best viewing depending on your computer's operating system and color settings.

 PC running Windows (any color depth):
    IE and wxloop.cgi works great, better than any other browser
    or any of the other configurations mentioned below.  Set disk
    cache to 80 MB or higher and screen resolution to at least
    1024x768.  I use 1152x864 24-bit color in Windows ME.

 Linux on a PC (16-, 24-, or 32-bit X color display -- one of these is
 usually chosen):
    Best: run IE under vmware (a product you must purchase) and use
          Web interface   
      ok: use wxloop from command-line
    slow: any Web browser under X

 Linux on a PC with 8-bit color -- not the norm:
    use wxloop on the command-line

 SunOS (8-bit and 24-bit X displays):
    use wxloop on the command-line

 OSF1 running any X configuration:
    use wxloop on command-line

Usage: wxloop.cgi?directory_key+files_to_loop[+options] where: directory_key --> can take two forms d1) master_path_file_entry --> any path variable from the master path file, include_files/master_path_file that has [jpg gif png tiff] images in the associated directory. Click here to see a list of possible choices. Also, see the examples below. d2)fulldir --> full path to an Atm. Sci. directory (starts with /home) that is Web accessible. NOTE: If fulldir contains /home/disk/*/username/public_html/$more then localURL automatically becomes /~username/$more and these can be looped over the Web. ALSO: All [jpg gif png tiff] images in fulldir must be the same dimension. ALSO: Need not be the entire directory, for examples that show the use of multiple subdirectories, see 7.x, 8.x, and 11.4 below. d2.1)-url localURL --> If fulldir is not of the form /home/disk/*/username/public_html, then you must specify this. local_URL is path starting with / that would come after http://www.atmos.washington.edu files_to_loop --> can take several forms Please study Examples below to understand this option. f1.1) num --> num is number of most recent images to display all --> display all images, can be more than 100 Recommended for use with -pat, see examples 7.x, 8.x, and 11.4 below. today --> display all images since midnight LST NOTE: No ending slash / f1.2) -n number --> same as f1.1 f2.1) timespec --> end/[duration/timestep] -- NOT FOR FORECAST DATA NOTE: Requires at least one slash / end --> [yyyymmdd]hh[:nn][p] (specify any unique UTC, or, if p is used at end, Pacific Local Time Zone, time closest to the current, e.g. 12 would be 12Z today if later than 12Z or 12Z yesterday if earlier, 102304 would 4Z Oct 23 of this year or previous year whichever has most recently occurred, 04:30 would be 04:30Z of most recent occurrence) DEFAULT is now if left blank. If not blank, hh is REQUIRED. duration --> a number in hours OR, Nx N = a number x = y (years), d (days), h (hours) m (minutes), s (seconds) Example: 5d (5 days) DEFAULT is 4 hours if left blank. timestep --> a number in hours OR, Nx N = a number x = y (years), d (days), h (hours) m (minutes), s (seconds) Example: 1h (1 hour) DEFAULT varies with image type to give all images. f2.2) timespec --> initialization/start/end/timestep -- ONLY FOR FORECAST DATA Requires at least three slashes ///. see examples 6.1, 6.2, 6.3, and 7.2 below. initialization --> [yyyymmdd]hh[:nn] (specify any unique UTC time closest to the current, e.g. 12 would be 12Z today if later than 12Z or 12Z yesterday if earlier, 102304 would 4Z Oct 23 of this year or previous year whichever has most recently occurred, 04:30 would be 04:30Z of most recent occurrence) DEFAULT is now if left blank. If not blank, hh is REQUIRED. start --> in hours, DEFAULT is 0. As of version 1.18 1/23/2004 this may now be a negative number which would take all analyses back to the time start hours before the selected initialization. end --> in hours, DEFAULT is end of model run (as appropriate). timestep --> in hours, DEFAULT is 1 (see timestep above) f2.3) timespec --> vvalidtime/start/end/initstep -- NEW as of 3/1/2004, ONLY FOR FORECAST DATA Requires at least vhh///. see examples 6.4 and 6.5 below. validtime --> v[yyyymmdd]hh[:nn] (time matching is more simplistic that used above in f2.2. Here, if partial times are used, then the remainder of the time is filled in with the current time's values. Hence, 3112 would be 12Z on the 31st of the current month even if the current month doesn't have 31 days!) NO DEFAULT, 'v' and hh are REQUIRED. start --> in hours, DEFAULT is -7 days. end --> in hours, DEFAULT is +16 days. initstep --> hours between initializations, DEFAULT is 12 hours. f3) full form --> user specifies start end and interval see example 2.3 below [-]start YYYYMMDDHH[:NN] --> full start time [-]end YYYYMMDDHH[:NN] --> full end time interval Ns --> Nx N = a number x = y (years), d (days), h (hours) m (minutes), s (seconds) Example: 1h (1 hour) options: -save | -savedir=$path --> NEW as of 1/10/2010 save files to current or specified directory. No effect when run from Web, but outputs the URL that would loop these files provided the directory is accessible to the U.W. Web server (i.e. under /home/disk/user_www/, /home/disk/funnel, or /home/disk/data/images). USE THIS TO SAVE IMPORTANT LOOPS THAT YOU DON'T WANT AGED OFF. -h(elp) --> print this help message -pat pattern --> file names follow the given pattern(s) which can contain subdirectories. Note: use (x|y|z) and .* style regular expressions. Use this with all from f1.1 above, see examples 7.x, 8.x, and 11.4 below. Also, certain time patterns can be used which will expand automatically: YYYY = year MM = month DD = day of month HH = hour (use H3,H6,H9,H12,H18,H24 to match nearest 3,6,9,12,18,24-hour time NN = minute SS = second JJJ = day of year 1 to 366 -v(ersion) --> print the version number of this program -update nsec or -ui nsec --> update the loop every nsec seconds -noauto --> disable auto-update feature. simple --> use file's name in title, without substitutions Examples:

Problems: o The Browser's Back Button Does Not Work Resolution: Some browsers don't interact well with frames. Use my back button displayed in the upper left frame. o Images Disapper when Loop Stops Resolution: In some versions of Internet Explorer, you need to click on the Tools --> Internet Options --> General (a tab) --> Tempororay Internet files -> Settings (a button) and change it to "Check for newer versions of stored pages" "Automatically" or "Never" o Restricted access data does not work for me Resolution: You must be associated with our department in order to obtain the correct username and password to use for access to these restricted images. Your departmental username and password will not work. Once you've obatained the correct login info from the computer support people, you should load a loop with a single image, such as this. As long as your browser session stays open, you can then access the other restricted data without having to log in again. NOTE: If you accidentally select a longer loop, your browser may open a login window for each image in the loop. You still only need to enter the username and password in one window, and you can then click the cancel button for all other windows. o Looping is Slow Resolution: see Optimizations above
