[Bioperl-l] A question about the perl code

[Alex Zhang]

Dear all,

I made a group A which includes 16 combinations of any
two nucleotides like: AA,AC,AG,AT,
CA,CC,CG,CT,
GA,GC,GG,GT,
TA,TC,TG,TT          

If  I randomly got a pair like AC, I want to exclude
AC, AT, AG, AA, TC, CC, GC. In other words, I want to
exclude the pairs in group A which has the same
nucleotide with the pair randomly selected. Can
anybody suggest me how to approach this using Perl?

Thanks!
   Alex
