We are pleased to announce that the EdGCM 4.0 public beta release is now available for Macs running OS X 10.7 (Lion) or later.
The transition to an EdGCM version compatible with OS X 10.7 and 10.8 required extensive alterations of the software code, mostly "under the hood." Users should be aware that some aspects of the EdGCM suite won't look quite the same as in version 3.2; however, we have worked hard to preserve the suite's functionality, so if you learned to use EdGCM 3.2, you'll have no trouble using the 4.0 beta.
WARNING: Old versions of EdGCM MUST BE COMPLETELY REMOVED from your computer before installing the EdGCM 4.0 beta.
If you have simulations to transfer from your old copy of EdGCM to the EdGCM 4.0 beta, please follow the upgrade instructions detailed at the bottom of this post BEFORE installing the EdGCM 4.0 beta. Launching the EdGCM 4.0 beta before removing old versions will corrupt the database, and you may lose all your prior simulation setup information.
KNOWN ISSUES AND BUGS
1. Mac OS X 10.8 (Mountain Lion) users ONLY must take the following steps during installation:
a. As of OS X 10.8, Apple has stopped distributing X11 as part of their standard system software. Since X11 is required for EdGCM’s scientific visualization (EVA), users running OS X 10.8 need to download and install an app called XQuartz (the free version of X11 for Mac). It’s easy to install - just mount the disk image and double-click the installer package, then follow the prompts. Download XQuartz from here:
http://xquartz.macosforge.org/downlo...artz-2.7.4.dmg (66.9 MB)
b. In System Preferences you must have the radio button in the Security and Privacy panel set to “Allow applications downloaded from: Anywhere”. This preference can be returned to the higher security settings once you have run the EdGCM software once.
2. Some beta testers have reported problems, such as failure of the user interface to launch various functions, when the EdGCM 4.0 beta is used with Mac OS X 10.6 (Snow Leopard). If you choose to try the EdGCM 4.0 beta release with Snow Leopard and encounter similar problems, we recommend that you either step back to EdGCM 3.2 (b926), or upgrade your system software to OS X 10.8. The EdGCM 4.0 beta has not been tested under OS X 10.5 (Leopard).
3. The first time you use each feature in EdGCM 4.0 (click any buttons in the Toolbar, Setup Simulations, Analyze Output, EVA, etc.) there may be a delay that lasts up to 45 seconds before an action occurs. This is because many buttons in EdGCM launch secondary applications that run in the background. When programs are started for the first time on a Mac, the operating system brings up a security warning, usually something like: “This is an application that was downloaded from the internet. Are you sure you want to start it?” For an unknown reason, many of the programs used by EdGCM are taking 30-60 seconds to bring up this warning message. Therefore, it may seem like nothing is happening after you’ve clicked a button. BE PATIENT and wait to see if the security warning eventually comes up. If nothing happens after 60 seconds you may need to try to quit and restart EdGCM. After each function of EdGCM has been used once, and you have approved their use by clicking OK on the security warning, all features of EdGCM should operate without warnings or delays.
4. When a run is selected in the Toolbar’s run list before the Setup Simulations window is opened, the data in the Setup Simulations window is not synced correctly. After opening Setup Simulations, always click to re-select the desired run in the Toolbar to sync the form.
5. The play button on the Toolbar is sometimes non-responsive. If this occurs, select a different run in the run list, switch back to the desired run, and try again. If this fails, quitting EdGCM and restarting usually fixes the problem.
6. In the Go menu, choosing Go > EdGCM 4D Folder opens the wrong folder IF you have placed an alias of EVA in the EdGCM folder.
7. The Permissions and Cleanup functions have not yet been tested in EdGCM 4.0.
8. The vector length in EVA-produced maps is not a function of cell size.
UPGRADING FROM AN OLDER VERSION OF EDGCM TO THE EDGCM 4.0 BETA
These steps are only necessary if you want to transfer simulations or run output from EdGCM 3.2 or earlier. If you have no simulations or run output to transfer, simply delete the old EdGCM folder before installing the EdGCM 4.0 beta.
1. Open your previous copy of EdGCM.
2. From the Window menu select Simulation Library and in the window that opens select a run you want to transfer from the list (each run must be moved individually – sorry!).
3. Click on the "Export" button at the bottom of the window and choose a name and location to save the file.
4. Repeat steps 2 & 3 for each simulation you want to transfer.
5. Quit the old version of EdGCM.
6. Next move all of the desired run folders from the EdGCM/Output folder to another outside of the EdGCM folder (the Desktop works fine). Note: if you want to transfer all the runs from your old copy of EdGCM you can simply move the entire Output folder to the Desktop. YOU MUST DO THIS STEP IF YOU WANT TO PRESERVE YOUR OLD RUN OUTPUT FILES AS WELL.
7. Now you can safely delete the old EdGCM folder.
8. Install the EdGCM 4.0 beta.
9. Open EdGCM 4.0 beta for the first time (double-click the EdGCM 4.0 alias in the EdGCM folder or double-click the file “EdGCM.4DB” in the EdGCM:Database folder. If you have purchased a license key, please enter it in the Registration window when asked; otherwise, continue in demo mode.
10. Open the Simulation Library window from the Window menu.
11. Click the Import button at the bottom of the window and use the Open dialog box to choose the .xml file that you wish to import.
12. A dialog box will appear identifying the run you are importing and, critically, whether or not it is a duplicate of an existing run (which would then be overwritten if you choose to continue with import). If you wish to continue, click the Import button. After the import is complete, quit EdGCM and restart to allow the database to update properly.
13. If you have saved run output from your older version of EdGCM, you may now move it into your current EdGCM/Output folder. The associated run names in the Toolbar will then show those runs as having been completed.
