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 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 options.
