Add-on

As described in Part 2 of this tutorial, we can animate isocontours of an electrostatic potential. Here, I'll describe how to save images from this animation that you can later use for presentation or to embed in a website. Click on the Vision icon located on the Toolbar. Use File → Close to close APBSIsoContour network, if present.  Download attached APBSIsoContour_pmvnet.py and open this with Vision. This is modified version of the nework with added Grab Image and Save Image nodes from Imaging library.  Make directory called foo where we can  store saved images.  Click on Compute → Electrostatics → Isocontour Potential and press Animate button. This should create a bunch of images under foo. Now you can use ImageMagick or any other software to make animation from these images. With ImageMagick installed you can simply type animate foo/*.png and save as gif.
