Lesson 2: Selection

Getting started: click to tools -> selection or click on this icon

2.1 Select in tree

You can make specific selection of segments, residues or atoms by checking on the boxes in front of them and then view selected parts in different modes . Click on the boxes to deselect.

Now, in the tree, select Hetatms, then choose Ball-stick mode for selection. You’ll see this image. Remember that this macromolecule is a dimer

2.2 Selection

In Selection Category, you have three options : Atoms, Residual and Radial Range

2.2.1 Atoms

Select atoms from 100 to 200 :

• In Selection Category, click to Atoms.
• Then you’ll see an empty box, type 100-200 in it
• Click on Select.

you’ll see this image

2.2.2 Residues

Select residue 30 and residue 50 then viewing them in Overlap Sphere mode

• In Query Category, click to Residues.
• Then you’ll see an empty box, type 30,50 in it
• Click on Select
• In View modes, choose Overlap Sphere

The selected residues are in green. However, You can easily change their color as you wish by clicking on Color options.

2.2.3 Radial Range

Choose ligand as a center and select all atoms within 5 angstrom.

• In Query Category, click to Radial Range.
• Then you’ll see an empty box, type 5 in it
• Then choose Components
• Select Ligand
• Click on Select
• In View modes, choose Overlap Sphere

You can also choose atoms, residues as a center
