Plotting other structures onto MSM

[sonyahanson]

I guess we need to check this a bit more thoroughly in general re: ensembler models, but currently have a basic question:

If I plot the first frame of run0-clone0.h5 is that equivalent to plotting the starting structure?

It's not exactly the same, but it should be close. This frame corresponds to the coordinates after equilibration, which involves some degree of structural relaxation.

[sonyahanson]

Cool. So I did some exploration here, and there does seem to be some discrepancy. Hard to tell if there is some dynamics that's happening super fast or if it's because we're doing something wrong. Result fir Abl using first frame of run0-clone0 vs implicit refined 2HZ0 (starting structure based on RUN0/template.txt):

Similar for Src:

Well, both points seem to lie inside a basin of high density, although the
src is strange that the the points are well-separated on the slowest
eigenfunction.

Would be cool if the data munging code could include the starting structures as the first structure in each trajectory.

After talking to Kyle it does seem like there was a ~10 ns equilibration before starting the simulation, which probably explains this difference.
