[Bioperl-l] aminoacid properties of a sequence

[luisa pugliese]

 Hi bioperlers,
     I am looking for a method to link somehow the residue number present in
 the pdb file to the aminoacids of its sequence, so that when I put the
 sequence into an alignment and I slice the alignment, I can retrieve which
 are the residue numbers of the aminoacid present in the sliced alignment.
 Does anybody knows if there is a clean method to do this instead of writing
 some perl code?
 Thank you to all
 Luisa
