Greetings all. I am new to the site (at least as a registered user), but plan to step up my attendance here as I am writing more and more Perl these days. Here is my question and I hope someone out there has a solution for me.

Here is what I currently have, in a hash:

%hash= (  Group1 => 'ATG1,ATG2,ATG4,ATRG7',
        Group2 => 'ATG1,ATG9',
        Group3 => 'FYCO1,LSM2'
        );

[download]

What I would like to do is end up with something like this:
newGroup1 = ATG1,ATG2,ATG4,ATRG7,ATG9
newGroup2 = FYCO1,LSM2

Basically, if a value from 1 group (key) is found as a value from another group then I want to combine the values from both of those groups into a single set of values. I hope that makes sense. I've been working on this for a couple of days now and can't figure a good way to do it. :)

Thanks for any help! Glad to be a part of this site now.
