Re^3: random pairs

Perl "warnings" is trying to tell you that $element{"interactions"} is uninitialized (undef). That probably means you "forgot" to give it a value previously. Check the program- and data-flow and see where you went wrong.

Probably @{$pop{$element{interactions}}} is not doing what you expect. I think perhaps you mean something more like @{$pop{$element}{'interactions'}}

I keep getting errors about $element and $pairs being uninitialized. I was wondering what you had set for the value of those two elements for your loop. I want to store $pairs into an array by the value of $element but I can't.	[reply]

Difficult to say why you get these warnings. By now I have lost track of how your program looks and I cannot reproduce these warnings in my script. I guess the problem is with this code: `push @results, $element.'-'.$pair; foreach (@results) { ($element.','.$pair) = split; $element{$_} = $element; } }` [download] You are `split`ting the elements of `@results` on whitespace and there is no whitespace in these elements, so `split` is not doing what you think it does. Also, `($element.','.$pair)` looks really strange. What are you trying to do with it? I have never seen his on the left side of an assignment.
