[Octopus-users] Basics of Visualization Tool known as Octopus

[David Strubbe]

Christian,

This mailing list is for the Octopus TDDFT physics software, hosted at
www.tddft.org/programs/octopus, which is not a visualization tool. Based on
your message, I think you are referring to a different code called Octopus,
and we won't be able to help you.
