Re^3: array references

I do not understand what you mean - see How do I post a question effectively?. Specifically, if your code is not behaving as expected, you should post sample input and expected output (both wrapped in <code> tags) so that we can replicate your issue.

A good bug report is worth a thousand words.

for example PF0000005.3 has two neighbor PF11001.3 in first line and PF00389.24 in fifth line.	[reply]

Read through Basic debugging checklist. I'd bet the issue is that `@AoA` doesn't contain what you think it does. Specifically, because there is no white space between what looks like the first two entries in `AAA41250.1...........PF0000005.3 PF11001.3 PF00389.24 PF10417.3`, the first element (`PF0000005.3`) is getting dropped in your split. Perhaps `my @chunks = split /\s+\|\.{2,}/;` would work better for you. I suspect that this is not the balance of your bugs, but if you follow the steps in Basic debugging checklist and use Data::Dumper judiciously, you should be able to get this resolved.
