Dear O-verlords,

Has anybody any experience using Richard Lavery's Nucleic Acid analysis program, CURVES? One of the output options is to generate a PDB file containing a simplified helix but on display in O, all the points are not joined up, giving just *'s and lines through the P's and C4'-C3' bonds. Has anybody got a jiffy to connect these up?

I guess you'll have many answers. what you need to do is declare your P's as the alpha carbons of your molecule. there is a data base entry called "your_mol_MOLECULE_CA". you change the " CA" into " P". then you need to change the max distance between ca's. this is in "your_mol_MOLECULE_CA_MXDST". give it 10. A for example. then you can make a ca object of your molecule and it should connect the "ca"'s.

Valerie is correct; I think it's even in the FAQ (which also explains that CA does *NOT* mean alpha carbon, but central atom)
