[Visualpython-users] contributed code errors

[roberto <rob...@gm...>]

hello,
i downloaded the following demo files: gas-KE_07.py from
http://lurbano-5.memphis.edu/GeoMod/index.php/Main_Page

and encountered this error
gas-KE_07.py", line 213, in <module>
    r = pos-pos[:,NewAxis] # all pairs of atom-to-atom vectors
NameError: name 'NewAxis' is not defined

also, the atoms do not move at all nor the slider is working

the very same problem is in the code: nebula_20p.py

if anyone has solved the issue, let me know
thank you in advance
