Hi,<br><br>I&#39;m trying to measure the distance between the N-termini (or the first known residue) of a batch of dimeric proteins. The two proteins are different chains. I know how to do this by hand, but am exploring different ways to script it. It may be best to avoid using chimera entirely, but I thought I&#39;d check to see if anyone knows a clever way to select the residue closest to the N-terminus when it&#39;s not residue #1.<br>
<br>Thanks for your help.<br><br>Michel <br>
