Thank you so much!! your suggestions really helped. I apologize for the formatting errors. I hope its not too bad this time.

Can I ask you one more question. With this input file (below):
gene_a gene_b
gene_b gene_a

I get the following output:
gene_a gene_b

If the input file is something like this:
gene_a gene_b
gene_b gene_a
gene_c gene_a
gene_a gene_c
gene_c gene_b
gene_b gene_c

Then I want the program to output the following:
gene_a gene_b gene_c

instead of:
gene_a gene_b
gene_b gene_c
gene_c gene_a

The thing is I am looking for pairs for which column[0] is equal to column1 and vice versa. This can happen for any combination of numbers (as I showed with three above a, b and c). Can you provide your suggestion in this case. I would really really appreciate it!

Thanks

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
