[Bioperl-l] Bioperl Module for Computing Background Distributions

[Wijaya Edward]

Dear Expert,
 
Is there any existing Bioperl module that 
computes background distributions of nucleotides
given a set of DNA sequences?
 
Basically it computes:
 
    frequency of nucleotide A(denin)  / Total number of bases
 
and so forth for T or C or G.
