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 <a href="pro.html"> PROBE </a> . <br><br> <table border=2 cellspacing=2 cellpading=0> <td align="left"> STYLE </td> <td align="left"> THICKNESS </td> <td align="left"> TYPE </td> <tr> <td align="left"> 0 </td> <td align="left"> Invisible bonds. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> 1 </td> <td align="left"> A single line. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> 2 </td> <td align="left"> Three lines. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> 3 </td> <td align="left"> Five lines. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> 4 </td> <td align="left"> Seven lines. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> 5 </td> <td align="left"> Nine lines. </td> <td align="left"> Fixed width. </td> <tr> <td align="left"> nic <br> nice </td> <td align="left"> Curved bonds, conical sticks or cylindrical sticks, <br> depending both on the bond probe radius and the atomic <br> radii.

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, it is more convenient to use the command BONDS STICKS. If your atoms are drawn using different radii, the bonds will appear conical. For more details, read also the text about the command <a href="bon.html"> BONDS </a> . <br><br> <font color=#880000> <b> NOTES <br> </b> </font> (1) Invisible disulfide bonds (style 0) are not treated as hidden - they are just invisible. <br><br> (2) The nice bond style is allowed for ordinary covalent bonds and for disulfide bonds, but not for hydrogen bonds. <br><br> (4) Remember that the nice disulfide bond style works only for the following atomic styles: SMALL, SM2, COVALENT, CO2, SPACEFILL, SP2, BIG and BI2. <br><br> <font color=#880000> <b> RELATED COMMANDS <br> </b> </font> PRO (PROBE) is used to set the probe radius. ATO (ATOMS) is used to change the drawing style for atoms. SSB is used to change the bond drawing style for disulfide bonds. STI (STICKS) is used to change the stick radius. BALLS is used to set the ball radius. <br><br> <hr size="3"> </html>
