ls -1 *.xyz |sort -n > filelist.datThis creates a list file of all the xyz files in the current directory according to the numerical/alphabetic order. The name of the file list in this case is filelist.dat.
At the bottom there is a text field that indicates the xyz file currently rendered at Aviz display window.
The option of continuous browsing is somewhat a preliminary version of a possible animation i.e. before snapping png files. One can try different viewpoints and determine the best one for the animation.
Stopping the continuous browsing before changing the viewpoint is recommended, since changing it during the continuous browsing is a very grueling task. Hence, find a nice viewpoint and then click on Cycle. If you want to change the viewpoint, press on Cycle to stop the continuous browsing, change the viewpoint and then press on Cycle again. Also, for the same reason, change the quality of the spins to 'Low' before activating the continuous browsing, and when you choose to snap png images, change it again to 'High' or 'Final'. After choosing the desirable viewpoint it is time to turn the renderings into image files.
3. As mentioned, Aviz saves a rendering as a png file. In the case of creating animations with fixed viewpoint, the easiest way is to press on AutoSnap, then on Cycle and let the continuous browsing run. As long as the AutoSnap button is depressed, png files of the rendering will be saved. All the image files will be saved in the same directory of the xyz files. One can also snap png files manually by pressing SingelStep (or FastStep) then on Snap, then again SingelStep and so on.
4. Aviz indicates which rendering is last saved at the bottom of the Aviz interface:
Since Aviz doesn't stop the continuous cycling by it self when reaching the last xyz file in the list, and since AutoSnap is still depressed, one should notice when one cycle is over and stop the png autosnapping by pressing Autosnap. To stop the continuous browsing press Cycle.
5. The result of the above steps is a sequence of png files that can constitute an animation. More details about converting png files to animation here.
