crdfluct

Calculate atomic fluctuations (RMSF) for atoms over time blocks.

[crdset <crd set>] [<mask>] [out <filename>] [window <size>] [bfactor]

Calculate atomic positional fluctuations for atoms in <mask> over windows of size <size>. If bfactor is specified, the fluctuations are weighted by $latex \frac{8}{3} \pi ^2 $ (similar but not necessarily equivalent to crystallographic B-factor calculation).

Units are $latex \AA $, or $latex \AA^2 \cdot  \frac{8}{3} \pi ^2 $ if bfactor specified.
