| 00:01 | Hello everyone. |
| 00:02 | Welcome to the tutorial on Introduction to GChemPaint. |
| 00:07 | In this tutorial, we will learn: |
| 00:11 | *About GChemPaint |
| 00:13 | *Uses and Benefits |
| 00:16 | Installation Open a new file |
| 00:20 | *Menubar, Toolbar and Status bar. |
| 00:25 | We will also learn about: |
| 00:28 | *Display area |
| 00:30 | *Document properties |
| 00:32 | *Using tool box and |
| 00:34 | *Saving the drawing with extension .gchempaint. |
| 00:40 | Here I am using |
| 00:42 | Ubuntu Linux OS version. 12.04, |
| 00:47 | GChemPaint version 0.12.10. |
| 00:53 | To follow this tutorial you should have knowledge of, |
| 00:59 | basics of Chemistry upto VIII standard. |
| 01:04 | GChemPaint can be very easily installed using Ubuntu Software Center. |
| 01:12 | For more information on Ubuntu software Center, |
| 01:16 | please refer to Ubuntu Linux Tutorials on our website. |
| 01:23 | What is GChemPaint? |
| 01:26 | GChemPaint is a two dimensional chemical structure editor. |
| 01:32 | It has a multiple document interface. |
| 01:37 | GChemPaint allows you to, |
| 01:40 | *Draw and display two dimensional chemical structures. |
| 01:46 | *Drag and drop of templates |
| 01:50 | *Change length, angle and width of the bonds |
| 01:55 | *Use Chemical Calculator to calculate molecular weight of compounds. |
| 02:03 | GChemPaint helps in: |
| 02:05 | *Easy visualization of chemical structures |
| 02:11 | *Converting two dimensional structures to three dimensional structures |
| 02:17 | *Magnification of structures |
| 02:21 | *Automatic and manual assignment of atoms. |
| 02:26 | Let's first see how to open a new GChemPaint application. |
| 02:33 | Click on Dash home >> Search bar appears >> In the Search bar type GChemPaint. |
| 02:41 | Click on the GChemPaint icon. |
| 02:46 | We can also open GChemPaint application from Terminal. |
| 02:52 | Press Ctrl, Alt and T keys simultaneously, to open the Terminal. |
| 02:58 | Type GChemPaint and press Enter. |
| 03:04 | GChemPaint application opens. |
| 03:08 | A typical GChemPaint window looks like this. |
| 03:13 | This is the Menu-bar. |
| 03:15 | GChempaint has a standard menu-bar like other window based applications. |
| 03:22 | Menu bar contain menu items like File, Edit, View, Tools, Windows and Help options. |
| 03:34 | Toolbar contains most frequently used commands as icons. |
| 03:41 | There are icons to open a New file, |
| 03:45 | Open existing file, |
| 03:48 | Save a file and Print a file. |
| 03:53 | This is the Display area. |
| 03:56 | Display area shows the structures and the contents of the file that we draw and edit. |
| 04:06 | We can drag and drop tools from toolbox into the Display area. |
| 04:14 | Status-bar displays information about current GChemPaint activity. |
| 04:20 | It also displays contextual information about menu items. |
| 04:28 | Now I will explain about Document Properties. |
| 04:33 | To open Document Properties window, |
| 04:37 | click on File menu. |
| 04:39 | Navigate to Properties and click on it. |
| 04:43 | Document Properties window opens. |
| 04:47 | I will drag the Document Properties window to maximize it. |
| 04:53 | Document properties window has the following fields. |
| 04:59 | Title- Let's type the title of the document as “Propane”. |
| 05:06 | Author's Name- let's type author's name as Madhuri. |
| 05:14 | Email– Let's leave it blank. |
| 05:17 | History – This field shows the Creation date of the document. |
| 05:23 | It also shows the Revision date of the document. |
| 05:28 | This means, it also shows the next edited date of the document. |
| 05:35 | Theme- let's leave this field as GChemPaint. |
| 05:39 | Comments- In the Comments field, we can add text related to the document. |
| 05:46 | Let's enter name of the compound and its formula. |
| 05:51 | Propane CH3-CH2-CH3 |
| 06:01 | Let's click on Close button to close the window. |
| 06:05 | Next let's learn about Toolbox. |
| 06:09 | Toolbox contains buttons for different tools. |
| 06:14 | Toolbox is displayed along with the active document window. |
| 06:20 | Let's now draw structures using Toolbox buttons. |
| 06:25 | Let's first draw the structure of propane. |
| 06:30 | Propane is CH3-CH2-CH3 |
| 06:36 | Let's use Add a Chain tool from Tool box to draw a Carbon chain. |
| 06:42 | Click on Add a Chain tool, |
| 06:45 | and then click on Display area. |
| 06:48 | A Carbon chain is drawn on the Display area. |
| 06:53 | To change the orientation of the chain, |
| 06:57 | click on Add a Chain tool. |
| 07:00 | In the Display area, click and hold the left mouse button to orient the chain. |
| 07:07 | Do not release the left mouse button until the direction of the chain is fixed. |
| 07:15 | Release the left mouse button after fixing the direction. |
| 07:20 | We see that carbon chain is drawn. |
| 07:24 | Note, once we click on the Display area, the chain length and orientation of the chain are fixed. |
| 07:33 | Let's now display atoms at each position on the chain. |
| 07:39 | Here we have 3 positions to display atoms. |
| 07:43 | Right click on the first position, |
| 07:47 | a Sub-menu opens. |
| 07:49 | Select Atom and then click on Display symbol, to display atoms at that position. |
| 07:59 | Like wise, let's display atoms on all positions. |
| 08:04 | Right click Select Atom. |
| 08:07 | click on Display symbol. |
| 08:12 | Here the structure of “Propane” is drawn. |
| 08:17 | Let's next draw a pentane structure on the same window. |
| 08:23 | Click on Add a Chain tool, |
| 08:26 | then click on Display area. |
| 08:29 | To increase the chain length, hold the left mouse button and drag the cursor. |
| 08:36 | Change orientation in the desired direction and release the left mouse button. |
| 08:43 | Let's display atoms on all positions. |
| 08:47 | Here we have 5 positions to display atoms. |
| 08:52 | To display atoms on the first position, right click. A sub-menu opens. |
| 08:58 | Select Atoms and then click on Display symbol. |
| 09:03 | Like wise let's display atoms on all positions. |
| 09:17 | Here the structure of pentane is drawn. |
| 09:21 | Let's now save the file. |
| 09:24 | click on File Menu select Save as . |
| 09:27 | Save As dialog box opens. |
| 09:30 | For File type, click on the drop down arrow. |
| 09:35 | Various save formats are seen. |
| 09:39 | Select 2D Chemical structure. |
| 09:43 | Type the file name as propane.gchempaint, |
| 09:52 | and click on Save button. |
| 09:55 | File is saved with .gchempaint extension. |
| 10:00 | With this, we come to the end of this tutorial. |
| 10:04 | Let's summarize. |
| 10:06 | In this tutorial we have learnt, |
| 10:09 | *About GChemPaint Uses and Benefits |
| 10:12 | *Installation |
| 10:14 | *Open a new file |
| 10:16 | *Menu-bar, Toolbar and Status bar |
| 10:20 | We have also learnt about: |
| 10:23 | *Display area |
| 10:25 | *Document Properties |
| 10:26 | *Using tool box and |
| 10:28 | *Save the drawing with extension .gchempaint |
| 10:33 | As an assignment I would like you to: |
| 10:36 | 1. Draw structures of n-hexane and n-octane |
| 10:41 | 2. Change the orientation |
| 10:43 | 3. Display atoms on each position |
| 10:47 | Output of the assignment should look like this. |
| 10:53 | Watch the video available at this URL: |
| 10:57 | It summarizes the Spoken Tutorial project. |
| 11:00 | If you do not have good bandwidth, you can download and watch it. |
