Hi guys,

As the title says, what I wanted to do is take one DNA file and put it into an array, do the same to a second DNA file and then insert one of the files somewhere in the other.

I have 2 files, DNA3 and DNA4

The content within the DNA3 file is: ATCGC

The content within the DNA4 file is: AAATTGC

What I want to do is to insert DNA4 into position #1 in DNA3, so the result would look like this: AAAATTGCTCGC

Currently my code looks like this: 

#!/usr/bin/perl -w

$DNA3file = 'testDNA3';

open(DNA3handle, $DNA3file);

@DNA3 = <DNA3handle>;

$DNA4file = 'testDNA4';

open(DNA4handle, $DNA4file);

@DNA4 = <DNA4handle>;

splice (@DNA3, 1, 0, @DNA4);

print @DNA3, "\n";

exit;

However, what is displayed really puzzled me:

ATCGC

AAATTGC

*Note, in my complier there isn't the space in between the output*

For the life of me I can't figure out what is wrong, I can run the above operation fine if I manually insert the DNA sequences into an array, but for large DNA set that is simply not possible. Really appreciate any help here, thanks for your time!
