Thank you for your time in replying. I'm sorry that I am not very good at asking questions; it isn't easy to know how much detail to include/not include. I always get it wrong :-(. I'll be honest in that I didn't understand what you meant by "To be able to run your code, I first had to remove the filenames from the downloaded files". I put the file names in because the code works on the principle that it reads in all .var files from the directory, so it made sense to me to put a header to say that they were named .var. Sorry if that was wrong.

I have managed to get a bit further with it. I realised that i should have defined my hash as $zygos{$uniqlocus} = $zyg. I also noticed that $locus needed to be non-unique.

I'll figure it out I'm sure. Thank you for your valiant efforts anyway!
