Hi all,
Im a bioinformatician at a research centre.So I am trying to build a supertree using the algorithm "TreeConstruct" described in section 7.2.3 of this article -
http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=0772DCA9649E3596FE5319A41B0F3193?doi=10.1.1.135.7740&rep=rep1&type=pdf
I have managed to write a code to read the triplets and display the connections (ignoring redundancy)
use strict;
use warnings;
@ARGV = ('a,b|c', 'c,d|e', 'a,d|e') unless @ARGV;
my %HoA;
foreach ( @ARGV ) {
m/^([a-z])[,]([a-z])[|]([a-z])$/ ;
push @{$HoA{$1}}, $2;
}
print "\n===========\@HoA=====\n";
print "from->to\n";
while (my ($key, $values) = each %HoA) {
print $key, "=> [", join(',', @$values), "]\n";
}
-----------OUTPUT----------
[hzing@localhost perl]$ perl input.pl
===========@HoA=====
from->to
c=> [d]
a=> [b,d]
But Im not able to proceed beyond this point. Especially the second and third step of the algorithm are very difficult for me to implement. Please help

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).
