CA strain for 2401041206373816311

--- normal mode 26 ---

This graph displays the distance variation between successive pairs of CA atoms in the two extreme conformations that were computed for this mode (DQMIN/DQMAX). Large distance variations can be an indicator for residue pairs that support the important strain in that particular normal mode movement. Note that residue pairs between chain breaks or at flexible ends of the protein may also exhibit large CA-CA distance variations. If more than one residues ae grouped together into a rigid block (NRBL>1), CA-CA distance variations between CA atoms in the same block will be very low.

This feature is still experimental and will be further developped in the future.
