[BioRuby] bio.pdb doubt

[K. Shameer]

Dear All,

Now I am almost done with my basic Ruby reading/coding. So far it was a
wonderful experience.

I am currently looking for a simple way to extract pdb co-ordinates from a
pdb file by using any inbuilt menthods available in bioruby.

For example, I need to extract a particular region of a PDB file with
multiple  chains ; say A:22 to B:50 (22 and 50 are residue numbers). Is
there any method in bio.pdb class to do this ?

Thanks,
K. Shameer
