It is not too late to insert <code> tags into your original post. You are able to update it any time.

As I understand you just want to output unique names of genes instead of raw rows. Than try this

#!/usr/bin/perl -lan # Usage: thisscript.pl genes.txt if ( $seen{ join ' ', sort @F }++ ) { $uniq{$F[0]}++; $uniq{$F[1]}++; } END { print for keys %uniq; }

And this:

Linux version: perl -lane '@u{@F}=() if $s{join "", sort @F}++ }{ print for keys %u' +genes.txt Windows version: perl -lane "@u{@F}=() if $s{join '', sort @F}++ }{ print for keys %u" +genes.txt

Where genes.txt is a file containing gene rows

Feel free to ask if you need explanations on the algorithm and it's implementation.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
