in thread how to output the final Tree into a file?

please excuse me but I m really new and it takes me a long time to understand many things

:) fragments which don't reproduce the error message, don't reproduce the error message -- you can't learn about the error message from those :)

diagnostics/perldiag/splain 

 perl -we" my $foo = 1; my $foo = 2; "
"my" variable $foo masks earlier declaration in same scope at -e line 
+1.

$ perl -Mdiagnostics -we" my $foo = 1; my $foo = 2; "
"my" variable $foo masks earlier declaration in same scope at -e line 
+1 (#1)
    (W misc) A "my", "our" or "state" variable has been redeclared in 
+the
    current scope or statement, effectively eliminating all access to 
+the
    previous instance.  This is almost always a typographical error.  
+Note
    that the earlier variable will still exist until the end of the sc
+ope
    or until all closure referents to it are destroyed.

    ok i can understand that i have already declared $treeout before. But I think that all the information of the tree that i need is stored in $treeout and i cant use it. Just emptying $treeout with undef has no point at all.

      That's right. Did you try: 

      while ( my $tree = $treeout->next_tree ) {
    for my $node ( $tree->get_nodes ) {
        printf $fh "id: %s bootstrap: %s\n", $node->id || '', $node->b
+ootstrap || '', "\n";
    }
}

      The way forward always starts with a minimal test.

      Ah, ok, now instead of code fragments, we're going with thought fragment?

      Why don't you post the whole code?

        ok.Here is another thought fragment: I don't like ....let me think how this is called.... ah yes .. i don't like Mr Clever guys. this is what i absolutely hate in the scientific field.

        i just need to know if it is any way to extract the information of $treeout to a file.thats all.
