Click on the '''Accept '''button in the pop-up. 

|| Click on '''Docking''' again, from the dropdown choose '''Ligand,''' select '''Open''' option.

Select '''ligand.pdbqt '''from the list of files in the window.

Click on the '''Open''' button.

A pop up window '''AutoDpf4 Ligand Parameters''' appears.

Read the information about the ligand.

Some default parameters are selected, leave them as such.

Click on the '''Accept ''' button in the pop-up. 

The pop up window closes
|-
|| Click Docking >> Search Parameters >> Genetic Algorithm. 

Cursor on '''Genetic Algorithm Parameters''' window.

Click the '''Accept''' button.

|| Click on '''Docking''' again, from the dropdown choose '''Search Parameters'''.

From the sub-menu select '''Genetic Algorithm'''.

'''Genetic Algorithm Parameters''' window opens.


You will notice that all the fields are auto populated.


We will leave the default parameters as such and click on ''' Accept''' button.
|-
|| Click Docking >> Docking Parameters. 

Cursor on the '''Set Docking Run Options '''window. 

Click the '''Accept '''button.

|| Next click again on '''Docking''' and from the dropdown choose '''Docking Parameters'''.


'''Set Docking Run Options ''' window opens.


Again you will notice that all the fields are auto populated.


We will leave them as such and click on ''' Accept''' button.

|-
|| Click Docking >> Output >> Lamarckian GA(4.2).


'''Autodock4.2 GALS Docking Parameter Output File''' window opens.

Type the file name in the File name field as''' 2vta.dpf'''.


The Files of type field is auto populated as '''dpf '''file.

Click on '''Save''' Button.

|| To save all the parameters as a single docking file; click '''Docking''' again.


Choose the '''Output''' option from the dropdown.


From the sub-menu choose '''Lamarckian GA(4.2)'''.


'''Autodock4.2 GALS Docking Parameter Output File''' dialog box opens.

Type the file name in the '''File name '''field as ''' 2vta.dpf'''.


The Files of type field is chosen as '''dpf''' file.


Click on '''Save''' Button.

|-
|| Click Run  >>  Run AutoDock.


Cursor on '''Run AutoDock''' pop-up.

|| Next, Click on '''Run''', Choose '''Run AutoDock'''.


'''Run AutoDock''' pop-up opens.

|- 
|| Cursor on '''Run AutoDock''' pop-up.
|| Here you will again need to set the '''Program Pathname ''' and '''Parameter Filename'''.

For me '''Program Pathname''' is already auto populated. 

Hence I will leave it as such.

Windows users may click on the '''Browse''' button and fill the path for the '''autodock4.exe file'''.
|-
|| Click on the '''Browse''' button next to the '''Parameter Filename '''field.

From the pop-up window, choose '''2vta.dpf''' from the home folder.

|| '''Parameter Filename ''' is also auto populated as '''2vta.dpf.'''


Click on the '''Browse''' button next to the field.


From the pop-up window, I will choose '''2vta.dpf''' from the Home folder.


Click on the '''Open''' button in the pop-up window.


Now the empty field next to '''Log Filename''' will automatically be populated as '''2vta.dlg'''.
|-
|| Cursor on the cmd field.
|| Here you may also find the command line if you prefer to use the terminal to run '''autodock4'''.
|-
|| Click on the '''Launch''' button.

Cursor on '''Autodock process Manager''' popup.
|| Click on the '''Launch''' button to run autodock4.

A pop-up titled '''Autodock Process Manager''' will appear. 

The process time depends on the '''parameter values''' you have set.

This will take 10 to 20 seconds.

The pop-up will automatically close when the process ends. 

|-
|| Cursor on the panel.
|| Viewers please note:

If the popup appears and closes quickly within 1 or 2 seconds, an error has likely occurred. 

If this happens, check your parameters and '''run '''the '''autodock''' again.
|-
|| Cursor on the home folder .

Cursor on output file '''2vta.dlg'''.

Right-click on '''2vta.dlg''' and open it using the text editor.
|| Open the''' home '''folder.

The output file '''2vta.dlg''' will be saved in the home folder.

We need to open the '''dlg '''file and check the last line to make sure '''autodock''' is successfully completed.


I will right-click and open the file using the text editor. 

|-
|| Cursor on '''2vta.dlg '''document.

Scroll to the last line in the document. 

Cursor on '''Autodock4 Successful Completion.'''

|| The file opened in gedit for me.

Scroll to the last line in the document. 

Here you will see, '''Autodock4: Successful Completion'''.

Close the text file and close the home folder..
