• Turn off rotation to increase responsiveness. The default rotation of the molecule consumes a large amount of computer resources. All operations will be much slower when rotation is on. It is recommended that you turn off rotation except when gazing tranfixed by the beauty of the (rotating) molecule.

• Let the Explorer catch up before proceeding. The and indicators will give you an impression of how long it takes the Explorer to complete various tasks on your computer. However, this mechanism is not foolproof. If you rush ahead, clicking on links or buttons before the Explorer has finished the previous task, it is possible to induce problems such as a permanent busy condition. If this happens, just close the window and start over -- but operate the Explorer at a more relaxed pace.

  The Comparator has no "Ready/Busy" indicators but uses the same internal mechanism. It is recommended that you use the one-molecule flavor of the Explorer enough to get a feel for how fast things work before you use the Comparator.

• NMR PDB files. Much effort has gone into convenience features for selecting and viewing models from multiple-model PDB files derived from NMR studies. However these options won't appear unless you load such a file. We recommend loading 1jsa (recoverin) to illustrate these capabilities. See the for more background on recoverin.

• Be patient when loading large NMR PDB files. Most NMR PDB files are several megabytes in size. While loading, there will be a long period when Chime is blank and nothing seems to be happening. Be patient, eventually the overlaid conformers will appear.

• Expand the command/message frame. Once you begin typing commands into the command-slot, you may prefer to increase the size of the lower right frame. Just drag the top boundary of this frame up to give yourself more room, and you'll be able to see the entire message box.

• Windows: if clicks make beeps, tap the Alt key. In Windows, sometimes an Alert message appears in a box and then immediately gets put in the background before you even notice the box has appeared. When this happens, clicking on buttons or links will beep but otherwise be ignored, pending your pressing the "OK" button on the (invisible) alert message. To get the message back into the foreground, tap the Alt key once.

The simplest method for building a linear presentation with Chime is explained in detail in , where a downloadable template is provided.

It is also possible to save the scripts with the PE. After you have obtained the desired image, use Chime's menu: Edit, Copy Chime Script. This copies the script into the clipboard. Now paste the script from the clipboard into a text editor (Windows: Wordpad; Macintosh: Word), and save it to a filename ending in .spt. Be sure to save it as plain MS-DOS/ASCII text.

There are some advantages to saving scripts with Chime instead of with RasMol. These are described in Shortening Scripts Saved from RasMol or Chime.

Scripts saved from either RasMol or Chime are often unnecessarily long and slow to execute, although they produce the desired image. It is fairly simple to shorten these scripts dramatically.

(Chime-generated scripts will run in RasMol as well as Chime. They contain a few commands not recognized by RasMol, but these simply generate harmless error messages in RasMol.)
