<p class="MsoNormal">Dear Chimera Users,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have a cryo-em map file and I would like to convert it
into a PDB file. How can I do that? I tried saving the .pdb file but it throws
an error saying “No model chosen to save”.</p><p class="MsoNormal"><br></p>
<p class="MsoNormal">Another question, If I open a .map file of a protein complex
in Chimera, how can I select a subregion (a particular chain) and colour the
surface of that part differently? I am not able to select the chain when I upload
the .map file.</p><p class="MsoNormal"><br></p><p class="MsoNormal">Thank you,</p><p class="MsoNormal">Aditya</p>
