Thank You!
I have installed the Algorithm::Cluster module. I have a very large distance matrix to solve. The function Algorithm::Cluster::treecluster(%param) seems to cluster genes or microarray. 

%param=(
  data => \@m,         #Wanted array reference, but got a 
                       #reference to .
  mask =>'',           #Parameter 'mask' is not a valid  
                       #matrix, ignoring it.
  weight =>'',         #Parameter 'weight' does not point
                       #to an array, ignoring it.
  transpose = '',      #Parameter 'transpose' must be 
                       #either 0 or 1 (got '')
)

I have stated the errors against its corresponding statements.

Any suggestion? Thanks
