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.
