please let us know.
 elNémo has been hacked on november 27th.
It has been moved away and runs again.
**Still some additional cleaning from time to time**
Sorry for the inconvenience.

Normal Mode Analysis for ID 2602061615123036985

The following table indicates for every normal mode its frequency (black, normalized relative to the lowest mode frequency) and its collectivity (magenta). If a second structure was submitted, the cummulative overlap between the normal modes and the conformational change is computed (red). The corresponding amplitude (dq) is then also given (green). Click on the mode link to obtain a visualization of the mean square displacement <R2> of the C-alpha atoms associated to each mode.

WARNING: there are 1 low-collectivity modes among your first 5 modes (see below)! The degree of collectivity indicates the fraction of residues that are significantly affected by a given mode. While low-frequency modes are expected to have collective character, computed ones sometimes happen to be localized. In such cases, they correspond to motions of some extended parts of the system, as often observed in crystallographic protein structures for N- and C-termini.
