Dear Sir/Madam,

I have done a long simulation. In order not to avoid the problem of outside box, I have used iwrap=1, in all my calculations.

However, when I do
rms first out xxx_all.rms .CA,C1

atomicfluct out xxx.bfactor byres bfactor

I found the profile is very strange. Please kindly refer to my attached excel files for the profiles.
I also need to do following analysis with ptraj, what should I do to get a reasonable profiles. It seems that when the molecule is moved to fit the box size, it affect all the analyzing parameters.

I also have to do clustering analysis and the following analysis, what should I do to solve the problem?

atomicfluct out xxx.nobfactor .CA,C1 byres
average xxx_average_nobox.pdb pdb noboxmatrix
correl .CA,C1 out xxx.corr byres
hbond distance 3.5 angle 120.0 solventdonor WAT O solventacceptor WAT O H1 solventacceptor WAT O H2 out xxx.WAT.hbond2

Many thanks.
Cat
