Hi Chimera fans,<br><br>1. If a pdb file contains more then one struture, how can I select and keep just one and get rid of&nbsp; the rest.&nbsp; Such as&nbsp; 1X95.&nbsp; It is a big mess after Chimera load the the DNA pdb structure.&nbsp; How can I leave just&nbsp; one double helix?
<br><br>2. Can Chimera do the extension of DNA.&nbsp; Such as 1X95 has the hexamer with the sequence of ATGCAT, can Chimera double it to a dodecamer with a sequence ATGCATATGCAT?&nbsp; It Chimera can not do that, do you know which software has such a function.&nbsp; I tried PyMol but did not get what I wanted.
<br><br>Thanks a lot.<br><br>Hong<br>
