<p class="MsoNormal"><span style="font-size:11.0pt">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I have a question about marker and marker link syntax. Suppose model #1 has chains A and B, and that chains A and B form a homodimer where each subunit has the same residue numbering. I would like to place
a marker at the midpoint between alpha-carbons of position 10 on A and 10 on B. In turn, I'd like another marker at the midpoint between position 20 on each of the two subunits. I would then like to draw a linker between the two markers. I would expect the
following syntax to work, but I get an error.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Any suggestions on how to fix the syntax, or is there an alternative approach?<o:p></o:p></span></p>
