A more "Perl-ish" way of doing the same thing...

use strict; use warnings; use Term::ANSIColor; use autodie; #Program to find motif site in a given protein sequence using files my $motif = "AGGGGG"; open( my $read, "<dna.txt" ); my @e = <$read>; $_ = join( " ", @e ); s/\s+//g; my @c; push @c, pos( ) - length( $motif ) + 1 while /$motif/g; s/$motif/color( 'bold green' ) . $motif . color( 'black' )/eg; print $_, "\n"; print "Number of sites the motif (AGGGGG) is present: ", scalar @c, "\ +n"; print "And the positions in the string are: ", join( ',', @c ), "\n\n" +;
The eliminates counting characters one at a time, as in the $i loop in the original, in favor of using pattern matching on the entire character string. I have found that eliminating loop counters wherever possible greatly reduces the number of bugs in my code.

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.
