SSB

NAME
SSB - change drawing style for disulfide bonds.

SYNOPSIS
SSB style

DESCRIPTION
Change drawing style for disulfide bonds. Disulfide bond style is defined separately from atom style. This command does not affect the ordinary covalent bonds: the command BONDS should be used for that purpose. Note that there is no separate keyword for curved bonds and sticks (nice style): the bond curvature is defined by the command PROBE .

STYLE	THICKNESS	TYPE
0	Unvisible bonds.	Fixed.
1	A single line.	Fixed.
2	Three lines.	Fixed.
3	Five lines.	Fixed.
4	Seven lines.	Fixed.
5	Nine lines.	Fixed.
nic nice	Curved bonds, conical sticks or cylindrical sticks, depending both on the probe radius and the atomic radii. This bond style is available for the following atomic styles: SMALL, SM2, COVALENT, CO2, SPACEFILL, SP2, BIG and BI2. Do not combine the nice bond style with atomic styles 0, 1, 2, 3, 4, 5, 6, 7, BALL and BA2.	Proportional.

NICE BONDS
Nice bonds may be curved or straight, cylindrical or conical, depending on probe radius. If this radius is small (like 0.8 angstroms), the bonds will be curved. Probe radius of 10 angstroms will give the straight bonds. If you want to draw the chemical bonds as cylindrical sticks, use the same atomic radius for all atoms and a relatively large probe. If your atoms are drawn using different radii, the bonds will appear conical. This is one of the things which make garlic different from most other programs: in garlic, sticks are just the special case of nice bonds. Most other programs are capable to draw just simple cylindrical sticks.

NOTES
(1) Unvisible disulfide bonds (style 0) are not treated as hidden - they are just invisible.

(2) The nice bond style is allowed for ordinary covalent bonds and for disulfide bonds, but not for hydrogen bonds.

(4) Remember that the nice disulfide bond style works only for the following atomic styles: SMALL, SM2, COVALENT, CO2, SPACEFILL, SP2, BIG and BI2.

RELATED COMMANDS
PRO (PROBE) is used to set the probe radius. ATO (ATOMS) is used to change the drawing style for atoms. BONDS is used to change the bond drawing style for the ordinary covalent bonds.
