Time	Narration
00:01	Hello everyone. Welcome to the tutorial on Edit Preferences, Templates and Residues in GChemPaint.
00:10	In this tutorial, we will learn to:
00:13	Edit Preferences
00:15	Manage Templates
00:17	Select and use ready Templates
00:20	* Add a New Template
00:24	We will also learn:
00:26	The uses of Residues and
00:28	To edit Residues.
00:31	Here I am using Ubuntu Linux OS version. 12.04,
00:38	GChemPaint version 0.12.10.
00:44	To follow this tutorial, you should be familiar with
00:49	GChemPaint chemical structure editor.
00:53	If not, for relevant tutorials, please visit our website.
00:59	I have already opened a new GChemPaint application.
01:03	Let's begin the tutorial by editing Preferences.
01:07	Go to Edit menu, navigate to Preferences and click on it.
01:13	GChemPaint Preferences window opens.
01:16	The first field, Default Compression Level For GChemPaint Files, is used when saving files.
01:24	By default, it is zero.
01:28	If not zero, the file will be compressed using gzip.
01:33	I will cover Invert wedge hashes in an another tutorial.
01:40	In GchemPaint, each document has an associated theme.
01:46	Let's retain the Default Theme as GChemPaint.
01:50	Now, I will explain about Arrows in detail, under Themes section.
01:58	Observe the different types of arrows on the tool box.
02:02	* Add an arrow for an irreversible reaction.
02:06	* Add a pair of arrows for a reversible reaction.
02:10	* Add an arrow for a retrosynthesis step.
02:14	* Add a double headed arrow to represent mesomery.
02:19	Let's add these 4 arrows to the Display area.
02:24	Click on Add an arrow for an irreversible reaction tool.
02:28	Then click on Display area.
02:31	Likewise, I will add other types of arrows to the Display area.
02:41	Select Arrows from the Themes field in the Preferences dialog box.
02:47	A Contextual menu opens.
02:50	Here we can increase or decrease Length, Width and Distance of the arrows.
02:57	Click on up or down arrow triangles with the mouse.
03:02	And Observe the changes in the arrows in the Display area.
03:10	Now let's learn about Arrow heads.
03:14	The default values of A, B and C are displayed here.
03:21	The A, B and C parameters help to vary the shape of the arrow heads.
03:28	Increase or decrease each one and observe the changes in the arrow heads.
03:38	Let's click on Close button, to close the window.
03:42	Let's clear the Display area.
03:46	Press Ctrl +A to select all objects.
03:49	Go to Edit menu, click on Clear.
03:53	Next, let's learn how to manage Templates.
03:58	Click on Use or manage templates tool.
04:01	The property dialog box opens below.
04:05	Property dialog box contains Templates with a drop down list.
04:10	List contains Amino acids, Aromatic hydrocarbons, Nucleic bases, Nucleosides and Saccharides.
04:19	Each item has a Submenu.
04:23	Let's select Aromatic Hydrocarbons and click on Benzene from the Submenu.
04:31	Benzene structure is displayed on the property page.
04:35	Now click on the Display area to display Benzene structure.
04:40	Likewise let's select Naphtalene structure and click on the Display area.
04:49	Select and place other structures on the Display area, on your own.
04:55	Let's save the file now.
04:57	Click on Save the current file icon on the toolbar.
05:01	Save as dialog box opens.
05:04	Enter the file name as Benzene. Click on Save button.
05:10	Now let's learn to add a New template to the existing Template list.
05:16	Click on Open a file icon from the toolbar.
05:20	A window with files and folders opens.
05:24	Select the file named “Hexane” from the list.
05:27	Click on Open button.
05:31	Click on Add button from the template's property page.
05:35	New template property page opens.
05:38	Property page has two fields – Name and Category.
05:42	Category field has a drop down list.
05:47	We can select from the list or add our own category.
05:52	Let's add a new Category, by typing Hydrocarbons in the text field.
05:58	In the Name field, enter the name of the compound as “Hexane”.
06:03	Click on the Hexane structure on the Display area.
06:07	It will be displayed on the New template property page.
06:12	Click on OK button.
06:15	Now, click on Templates drop-down.
06:19	Select Hydrocarbons category.
06:22	Observe that Hexane structure is added to the Template list.
06:27	Add Octane structure to Hydrocarbons category, on your own.
06:32	Let's close the hexane file.
06:35	Go to File menu, select Close to close the file.
06:41	Click on Select one or more objects tool to close the Templates property page.
06:47	Now, let's learn about Residues.
06:51	Residues are used to,
06:53	Find the nature of functional group attached to carbon chain.
06:58	Know the structure of functional group.
07:01	Add a new functional group to the database.
07:04	Go to Tools menu, click on Edit residues.
07:09	Residues window opens.
07:12	It has three buttons - New, Save and Delete.
07:18	New button has a drop down list.
07:21	Select n-Pr for from the list.
07:25	Identity tab shows Symbol and Name of the selected residue.
07:32	Formula tab shows the Skeletal structure of the selected residue.
07:38	Likewise, let's select s-Bu for Secondary Butyl.
07:44	Observe the Symbol, Name and Skeletal structure of the selected residue.
07:52	Let's now add a new residue - Hydroxy group.
07:57	To add a new residue, click on New button.
08:02	In the Symbol field type O-H.
08:06	Name it as Hydroxy.
08:09	Click on the Formula tab.
08:11	You will see a bulleted bond.
08:14	Place the cursor near the bond and press capital O.
08:19	A Submenu opens with O and Os. Select 'O'.
08:24	O-H group attaches to the bond.
08:28	Click on Save button.
08:31	Now, click on New button to view the list.
08:35	Observe that O-H residue is added to the list.
08:40	Let's click on Close button to close the window.
08:44	With this we come to the end of this tutorial.
08:48	Let's summarize.
08:50	In this tutorial, we have learnt to:
08:53	Edit Preferences
08:55	Manage Templates
08:56	Select and use ready Templates
08:59	Add a New Template
09:01	Uses of Residues and To edit Residues.
09:07	As an assignment: * Select and use Saccharides from Templates list.
09:12	Explore other residues.
