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.. This brings us to the end of this tutorial.
