8.7 Selection Tool

With this dialog box, you can select atoms, distances, angles, torsions and angles between two planes to perform a calculation. In the Selection Tool,  you can compile the atom list using the atom name, residue name, residue number format or the simple atom number.
As first step, choose the selection type (Distance, Angle, Torsion, Plane Angle, Multiple). The Multiple selection is needed if you want select one or more atoms without a geometric relation and it will be useful in the next VEGA ZZ releases.

At this point, press Add and automatically a default name will be shown. If you want rename it, just type in Name field.

The Open and Save buttons can be used to load and save the selections into a .sel file. For more information about this file format, click here.

Context menu

The context menu allows to add automatically all torsions (Add all torsions), all flexible torsions (Add all flexible torsions), open a selection file (Open), save all selections (Save As...) and remove all selections (Remove all). The same functions are replicated in the menu bar (File and Edit menus). The capability to add all flexible torsions is very useful to perform a conformational search.
When the selection is finish, you must click the Done button or select the File -> Close menu item to close the dialog window.
