Time Narration
00:01 Welcome to this tutorial on Modify Display and View in Jmol Application.
00:08 In this tutorial, we will learn to:
00:11 Rotate, zoom, move and spin the model on screen
00:17 Modify the view
00:19 Change the style of the display
00:22 Change the size and color of atoms and bonds
00:26 To display the model with axes and bound box.
00:30 Save the image in various file formats.
00:34 To follow this tutorial, you should be familiar with
00:37 Jmol Application window and
00:40 know to create and edit models using modelkit function.
00:45 If not, watch the relevant tutorials available at the following link.
00:51 To record this tutorial, I am using:
00:53 Ubuntu OS version 12.04
00:58 Jmol version 12.2.2 and
01:02 Java version 7
01:05 I have opened a new Jmol window with a model of 2-chloro-1-propanol on the panel.
01:12 We can rotate and zoom the model to get a better perspective of the structure.
01:18 To rotate the model, click on the “Rotate molecule” icon on the tool bar.
01:24 Click on the model and observe that the cursor changes to a hand icon.
01:29 Holding down the mouse button, drag the mouse on the panel
01:34 You can see that the model is rotating.
01:37 To zoom-in and zoom-out, place the cursor on the panel.
01:42 Move the mouse wheel upwards to zoom-out and downwards to zoom-in.
01:49 To move the model on the panel, place the cursor on the model.
01:54 Hold the Shift button on the keyboard.
01:57 Double-click and drag the mouse.
02:00 For a detailed description, refer to the Mouse Manual provided in the Pop-up-menu.
02:06 Open the Pop-up-menu and scroll down to About. Then select Jmol 12.2.2 and click on Mouse Manual.
02:17 If you are connected to the Internet,
02:19 a web page with “Mouse manual” appears on the screen.
02:24 Click on the panel to exit the Pop-up menu.
02:28 To automatically spin the molecule on the panel, open the Pop-up menu.
02:34 Scroll down to Spin and then click on option On.
02:40 We can see that the model is spinning on the panel.
02:44 To turn off the spin, open the Pop-up-menu again.
02:49 Scroll down to Spin and click on Off.
02:54 As an assignment-
02:56 Create a model of 2-chloro-3-Iodo-pentane.
03:00 Explore the Spin option in the Pop-up menu.
03:04 Change the direction of spin to Z-axis and rate of spin to 40.
03:10 As a hint: Use Set Z Rate option in the pop-up menu.
03:16 Your completed assignment should look as follows.
03:22 Let us now learn about the View menu.
03:25 View menu on the menu bar has options to view the model from various angles.
03:31 Click on the View menu.
03:33 Scroll down the menu and choose from the various options provided.
03:38 For example, I will choose Top view.
03:42 Click on the Top option.
03:45 The image on the screen shows how the molecule looks from the top.
03:50 We can save this view as an image in various file formats.
03:55 Click on the Save current view as an image icon.
03:59 A Save dialog box appears.
04:03 To select the file format, scroll down the options on the Image Type.
04:09 I will select JPEG format.
04:13 Open the folder in which you want the file to be saved.
04:17 I want it on Desktop.
04:19 Select Desktop and click on Open button.
04:24 In the File Name text-box, type “2-chloro-1-propanol” .
04:30 Go to “Files of Type” and select jpg.
04:35 Click on Save button.
04:38 The image will now be saved in JPEG format on the Desktop.
04:44 The style of display of molecular model can be modified in various ways.
04:50 Size and color of atoms and bonds in this molecule can be changed, if required.
04:57 We have an option to modify all the atoms in the molecule or a select set.
05:03 The default display of the model on the panel is of ball and stick.
05:09 To change the display into CPK Space fill, open the Pop-up-menu.
05:15 Go to Select and click on All to modify the whole molecule.
05:22 Open the Pop-up-menu again.
05:25 Scroll down to Style, select Scheme from the sub-menu.
05:30 And click on CPK Spacefill option.
05:35 The model on the screen is converted to CPK Spacefill model.
05:40 Let us now convert it back to ball and stick model.
05:44 Let's follow the same steps as before.
05:48 Open the Pop-up-menu.
05:50 Scroll down to Style, select Scheme and click on Ball and Stick option.
05:56 The model is now converted to ball and stick style display.
06:01 The size of the bonds can be changed using Pop-up menu, as well as Display menu on the menu bar.
06:08 Click on the Display menu and select Bond.
06:12 The sub-menu has options of bonds in different size diameter, in angstrom units.
06:19 For example, I will select 0.1 Angstrom and click on it.
06:26 Note the change in the thickness of the bonds.
06:30 We can also change the colour of atoms and bonds.
06:34 I want to change the colour of all the Carbon atoms in the model to yellow.
06:39 To do this, open the Pop-up menu and go to Select.
06:44 Scroll down to Element and click on Carbon.
06:48 Open the Pop-up menu again and select Color.
06:52 Then select Atoms and click on Yellow option.
06:57 All the Carbons in the model, now appear yellow in colour.
07:02 Let's see how to change the color of bonds.
07:06 Open the Pop-up-menu and select All.
07:10 Open the Pop-up-menu again.
07:12 Scroll down to Color, select Bonds from the sub-menu.
07:16 Scroll down and click on Blue option.
07:20 All the bonds are now blue in color.
07:23 We can display this model on the screen with X, Y and Z axes and within a bounding box.
07:31 Open the Pop-up menu, select Style
07:34 and Scroll down to Axes option.
07:37 From the sub-menu select Pixel Width .
07:40 I will choose 3 px. as pixel width.
07:44 We now have the model on the screen with all the axes.
07:49 To draw a bound box around the image, open the Pop-up-menu.
07:54 Scroll down to Style and select Boundbox from the options.
07:59 Select Pixel width and click on the pixel width 3 px.
08:05 On the screen, we have the model of 2-chloro-1-propanol in Boundbox with Axes.
08:12 To view the Boundbox clearly, we may have to zoom-in or zoom out.
08:17 Save the image and exit the program.
08:21 Let's summarize what we have learnt.
08:23 In this tutorial, we have learnt to:
08:26 Rotate, zoom, move and spin the model on screen.
08:31 View the model from various angles.
08:34 Change the style of the display.
08:36 Change the color of atoms and bonds.
08:39 We have also learnt to:
08:41 Display the image with axes and boundbox and
08:44 Save the image in different file formats.
08:48 For the Assignment-
08:50 Create a model of 3-amino-1-propanol.
08:53 Change the display to Sticks.
08:56 Change the color of hydrogens in the model to Green.
09:00 Change the color of all the bonds to yellow.
09:04 Your completed assignment should look as follows.
09:12 Watch the video available at the following link.
09:15 It summarizes the Spoken Tutorial project.
