Hi!<br>I'm trying and model a 7-helix trans-membrane receptor, as I don't like the way MODELLER models my helices, while I highly appreciate its loop modelling, I've been using the &quot;model-myini.py&quot; input script to model my receptor starting from a 
initial.pdb containing the 7 helices already modelled. Every MODELLER run ends with the <span style="font-style: italic;"><span style="font-style: italic;">&quot;</span>nselat__596E&gt; Atom index is out of range&quot;</span>

 error. Considering that this error changes the couple of atoms referring to any time I delete the corresponding residue in order to by-pass the error. I've attached to the mail the input files I used and the log file. Can you help me?
<br>best regards, <br>MG<br>
