如何在Pymol中更改角度?

我用这个

set_dihedral atom1_name, atom2_name, atom3_name, atom4_name, angle

例如

set_dihedral 22/C, 23/C, 26/C, 27/C, 130

所以我想改变这些原子的二面键

但是当我写的时候:

set_dihedral 23/CA, 23/C, 24/N, 24/CH3, 130

我有

SetDihedral-Error: Selection 1 doesn't contain a single atom/vertex.
SetDihedral-Error: Selection 2 doesn't contain a single atom/vertex.
SetDihedral-Error: Selection 3 doesn't contain a single atom/vertex.
SetDihedral-Error: Selection 4 doesn't contain a single atom/vertex.

答案 0 :(得分:0)

您确定3D文件中不包含一个以上具有相同原子名称的结构吗?您可以在此处发布.cif文件。或者,也许您必须使用其他选择语法(例如,“名称” C23等。请参见下文)。

例如,如果我使用stearic acid的结构,则可以正常工作:

set_dihedral name c1,name c2,name c3,name c4, 130

enter dihedral angle in PyMOL with a selection of four atoms
