Dear Chimera developers,
<div class=""><br class="">
</div>
<div class="">My apologies if this question has been asked before but I was not able to find an answer so far.</div>
<div class=""><br class="">
</div>
<div class="">I am dealing with PDB files that contain too many individual chains and as such need two-character chain IDs. Ideally I do not want to split the PDB-files (to be able and work with single-character chain IDs). In addition, the PDB-file also contains
more than 100,000 atoms and thus uses alphanumeric atom numbers.</div>
<div class="">It seems Chimera is not aware of the two-character chain IDs because selecting a certain chain in the GUI shows only single character chain IDs and it leads to the selection of the two distinct chains (e.g. chain AA and chain BA are both treated
as chain A). Is there a workaround?</div>
<div class=""><br class="">
</div>
<div class="">I’ve also noticed that saving such a PDB-file in Chimera changes all ATOM records to HETATM - I don’t know if this is related to the double-character chain IDs or alphanumeric atom numbers but this causes problems downstream because it’s very
difficult to change this back to ATOM records without also affecting true HETATM entries.</div>
<div class=""><br class="">
</div>
<div class="">Thank you for your help!</div>

<div class="">Best regards,</div>
