runavg | runningaverage
Calculate the running average of coordinates over specified window size.
runavg [window <window_size>]
Note that for backwards compatibility with ptraj
runningaverage is also accepted. Replaces the current frame with a running average over a number of frames specified by
window <window_size> (5 if not specified). This means that in order to build up the correct number of frames to calculate the average, the first
<window_size> minus one frames will not be processed by subsequent actions. So for example given the input:
runavg window 3 rms first out rmsd.dat
the rms command will not take effect until frame 3 since that is the first time 3 frames are available for averaging (1, 2, and 3). The next frame processed would be an average of frames 2, 3, and 4, etc.
