Thank you very much for your answer :)

Your answer seems quite interesting but I don't know why but I obtain too many "NA".

With de first part of the script I obtain for example

AA=> NA, NA,1,2,5,NA,NA,NA,NA,NA

instead of

AA=> 1,2,5

Perhaps is related with

my (undef,%hash) = split /[\t;=]/,$line;

because you are spliting 3 times, I don't know.

The final csv is

AA => NA,NA,NA

AB => NA,NA,NA

AC => NA,NA,NA

Perhaps is because the problem with de "NA".
