Atom selection
As for the "Analysis
" mode object(s) can be selected using the mouse left click. In "Edition
" mode selected atoms/objects are subjects to motion interactions using the mouse and it becomes complicated to check motion information with visual measurements. However using the "Tools
" menu it is possible to activate the "Measures
" selection mode (available when using the "Model edition
" dialog (see section 6.1.2.7):

The following provides an example of utilization of the "Measures
" selection mode:
Select a fragment in the model:
Switch to "
Edition
" mode (if not done already) and change the "Mouse selection mode
" to "Measures (Edition mode only)
". Then select some atoms in the model, and open the "Measures
" dialog (see section 5.1.3.2) to display some measurements:Start to move the selected fragment using the mouse left click+motion to rotate or mouse scroll click+motion to translate, by default, and if divided because of the PBC, Atomes will reconstruct the fragment (see figure 6.27 to modify that behavior):
You will see that when moving the fragment with the mouse the information displayed (inter-atomic distances and angles) is instantaneously refreshed:
