Slide Number 1 Title Slide	Hello everyone Welcome to this tutorial on, Introduction to GChemPaint
Slide Number 2 Learning Objectives	In this tutorial, we will learn About GChemPaint Uses and Benefits Installation Open a new file Menubar, Toolbar and Status bar We will also learn about, Display area Document properties Using tool box and Saving the drawing with extension .gchempaint
Slide Number 3 System Requirement	Here I am using Ubuntu Linux OS version. 12.04 GChemPaint version 0.12.10
Slide Number 4 Pre-requisites	To follow this tutorial you should have knowledge of, Basics of Chemistry upto VIII standard.
Slide Number 5 Installation	GChemPaint can be very easily installed using Ubuntu Software Center. For more information on Ubuntu software Center, please refer to Ubuntu Linux Tutorials on our website www.spoken-tutorial.org
Slide Number 6 About GChemPaint	What is GChemPaint? GChemPaint is a two dimensional chemical structure editor. It has a multiple document interface.
Slide Number 7 Uses of GChemPaint	GChemPaint allows you to, Draw and display two dimensional chemical structures. Drag and drop of templates Change length, angle and width of the bonds Use Chemical Calculator to calculate molecular weight of compounds
Slide Number 8 Benefits of GChemPaint	GChemPaint helps in Easy visualization of chemical structures Converting two dimensional structures to three dimensional structures. Magnification of structures Automatic and manual assignment of atoms
	Let's first see how to open a new GChemPaint application.
Click on Dash home >> Search bar appears>>In the Search bar type GChemPaint	Click on Dash home, Search bar appears. In the Search bar, type GChemPaint Click on the GChemPaint application
	We can also open GChemPaint application from Terminal.
Press CTRL+ALT+T >> open the Terminal	Press CTRL, ATL and T keys simultaneously to open the Terminal.
Type GChemPaint >>press Enter to open	Type GChemPaint and press Enter. GChemPaint application opens.
Show the Gchempaint window	A typical GChemPaint window looks like this.
Menubar	This is the Menubar. GChempaint has a standard menu-bar like other window based applications.
Point to the options as per the narration	Menu bar contain menu items like File, Edit, View, Tools, Windows and Help options
Point to Toolbar, New icon, Open icon, Save icon, Print icon	Toolbar contains most frequently used commands as icons. There are icons to open a New file, Open existing file, Save a file and Print a file.
Show Display area	This is the Display area. Display area shows the structures and the contents of the file that we draw and edit. We can drag and drop tools from toolbox into the Display area.
Point to Statusbar	Statusbar displays information about current GChemPaint activity. It also displays contextual information about menu items.
	Now I will explain about Document Properties.
Document Properties Click on File menu>>Navigate to Properties>>Click on Document Properties	To open Document Properties window, click on File menu. Navigate to Properties and click on it. Document Properties window opens. I will drag the Document Properties window to maximize it.
Show Document properties window	Document properties window has the following fields.
Show Title	Title- Let's type the title of the document as “Propane”
Show Author's Name	Author's Name- let's type author's name as Madhuri.
Show Email	Email– Let's leave it blank.
Show History	History – This field shows the Creation date of the document. It also shows the Revision date of the document. This means, it also shows the next edited dated of the document.
Show Theme	Theme- let's leave this field as GChemPaint
Show Comments	Comments- In the Comments field, we can add text related to the document. Let's enter name of the compound and its formula. Propane CH3-CH2-CH3
Click on Close button	Let's click on Close button to close the window.
	Next let's learn about Toolbox.
Tool box	Toolbox contains buttons for different tools. Toolbox is displayed along with the active document window.
Draw the structures	Let's now draw structures using Toolbox buttons. Let's first draw the structure of propane. Propane is CH3-CH2-CH3
Point to “Add Chain” tool	Let's use Add a Chain tool from Tool box to draw a carbon chain.
Click on Add a Chain>> Display area	Click on Add a Chain tool and then click on Display area. A Carbon chain is a drawn on the Display area.
Change orientation of Chain	To change the orientation of the chain, click on Add a Chain tool.
Display area>>click and hold the left mouse button	In the Display area, click and hold the left mouse button to orient the chain.
Do not release left mouse button	Do not release the left mouse button until the direction of the chain is fixed.
Release the left mouse button	Release the left mouse button after fixing the direction. We see that carbon chain is drawn.
	Note once we click on the Display area, the chain length and orientation of the chain are fixed.
Display Atoms.	Let's now display atoms at each position on the chain. Here we have 3 positions to display atoms.
Right click on first position	Right click on the first position, a Submenu opens.
Select Atom >> click on Display symbol	Select Atom then click on Display symbol, to display atoms at that position.
	Like wise, let's display atoms on all positions. Right click Select Atom click on Display symbol Here the structure of “Propane” is drawn
Pentane structure	Let's next draw a pentane structure on the same window.
Click on Add a Chain>> Display area	Click on Add a Chain tool, then click on Display area.
hold the left mouse button and drag the cursor.	To increase the chain length, hold the left mouse button and drag the cursor.
Change orientation >>release the left mouse button	Change orientation in the desired direction and release the left mouse button.
	Let's display atoms on all positions. Here we have 5 positions to display atoms.
	To display atoms on first position, right click. A submenu opens
Click on Atoms>> Display symbols	Select Atoms click on Display symbol
	Like wise I will display atoms on all positions. Here the structure of pentane is drawn.
Click on File>> Save As	Let's now save the file. Go to File Menu select Save as . Save As dialog box opens.
Click on File type drop down	For File type, click on the drop down arrow. Various save formats are seen.
Select 2D Chemical structure	Select 2D Chemical structure
In filename type propane.gchempaint>> click Save	Type the file name as propane.gchempaint and click on Save button. File is saved with .gchempaint extension.
	With this, we have come to the end of this tutorial. Let's summarise.
Slide Number 9 Summary	In this tutorial we have learnt, About GChemPaint Uses and Benefits Installation Open a new file Menubar, Toolbar and Status bar We have also learnt about Display area Document Properties Using tool box and Save the drawing with extension .gchempaint
Slide Number 10 Assignment	As an assignment I would like you to 1. Draw structures of n-hexane and n-octane 2. Change the orientation 3. Display atoms on each position Output of the assignment should look like this.
