[Bioperl-l] Count or weight matrix in bioperl?

[Sam Al-Droubi]

All,
  
  Say I have an array of nucleotide sequences of of length N.  I  want to calculate the count matrix (weight matrix). That is for each  position 1..N, I want to know how many As, Cs ,Ts and Gs there  are.  Is the code to do this already written in bioperl to build  this matrix if I pass it those strings?
  
  Please excuse my lack of knowledge as I am a new comer to bioinformatics.
  
  Thank you. 
  
  
  
  

Sincerely, 
Sam Al-Droubi, M.S.
