 Once all that is ready, run the script
-```cd ~/TAMV```<br>
+<blockquote>
-```./TAMV_GUI.py```
+cd ~/TAMV<br>
 ./TAMV_GUI.py
 It should require no arguments the first time it is run. It will guide you from there.
 When the script finishes, it will give you a G10 for each tool.  Put these in your config.g.
