Hi Chimera users, Recently I¹m switching from my favorite molecular graphics software ³Pymol² to Chimera. I find chimera very useful in terms of structural analysis and easy to drive through the smooth command line. I have a question regarding drawing H-bond in figures for publications: Is there a way to instruct the program to draw a H-bond Between two particular atoms in dotted (dashed) line style? I know that hbond¹ does a decent job in finding the H-bonds represented by solid lines. However, in the cases I tried the H-bond network found by hbond¹ Is a bit complicated and simplification is necessary for the figure. I wonder if the user can have a control over which ³psudobond² to draw between what atoms. This would make the program very handy for me. Thanks, Ibrahim -- Ibrahim M.
