Yes, I tried that but it wasn't very successful (seeing as my grasp of hashes is rather pathetic)

Here is what you need to do: Declare a hash Read the first file line by line, populating the hash iterate over the second file, and look up the values in the hash In your current program, you compare things to `$pdbchain`, so your hash keys have to be constructed exactly in the same way as `$pdbchain` Give it a try, and when you have problems, come back with more specific questions.

Please, when you have an instance like this, post your code. Doubtless someone here can find and correct the error. If you can't post it because it's long since been over-written, I'd suggest you look into a Version Control System. Sometimes good approaches get discarded because a detail or two gets in the way.
