I still can't get this to work. I am obviously missing something.
So what I want to do is:
Use an input DNA sequence and put in array.
For each element in array check if the element is a nucleotide. If not a nucleotide print "not a valid character at position xx".
In the end, print out the number of characters that were valid and the number of characters that were not valid, calculate the percentage of non-valid characters.
Does this make sense?
Thanks

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).
