How do I export images from a trajectory to png or pov files?¶
With ase-gui, you can choose
, but this is not fun if you need to do it for many images. Here is how to do it on the command line for a number of images:ase gui images.traj@0 -o image0.pov
ase gui images.traj@1 -o image1.pov
ase gui images.traj@2 -o image2.pov
If you have many images, it will be easier to do it using the Python interpreter:
>>> from ase.io import read, write
>>> for n, image in enumerate(read('images.traj@:3')):
... write('image%d.pov' % n, image, run_povray=True, pause=False,
... rotation='-90x,10z')
Here, we also:
run povray to generate png files
disable pausing between the images
set a rotation (choose
in ase-gui to select the best rotation angles)
Try:
>>> help(write)

abstract={The atomic simulation environment (ASE) is a software package written in the Python programming language with the aim of setting up, steering, and analyzing atomistic simulations. In ASE, tasks are fully scripted in Python. The powerful syntax of Python combined with the NumPy array library make it possible to perform very complex simulation tasks. For example, a sequence of calculations may be performed with the use of a simple ‘for-loop’ construction. Calculations of energy, forces, stresses and other quantities are performed through interfaces to many external electronic structure codes or force fields using a uniform interface. On top of this calculator interface, ASE provides modules for performing many standard simulation tasks such as structure optimization, molecular dynamics, handling of constraints and performing nudged elastic band calculations.}
