Hi,<div><br></div><div>I&#39;ve just downloaded your program and was trying to run some alignments between two peptides.  However, whenever I type in the command &quot;source&quot;, I keep seeing the following error message:</div>
<div>unrecognized command: &quot;source&quot;</div><div><br></div><div>Could you please help me?  I am able to run all the other commands, I just don&#39;t know why &quot;source&quot; is not recognized.</div><div><br></div>
<div>Thank you,</div><div><br></div><div>Pam Wang</div>
