<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hi Ryan,<DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>You can't import chimera into a "stock" Python interpreter. Due to some issues with using C++ classes as types, Chimera uses a custom version of Python. What you can do is use Chimera's version of Python as your interpreter, which you can do with "chimera --nogui yourScript.py". Now, frequently you want your script to take arguments -- and you want Chimera to pass them off to your script without using them itself. To do this you use the new "--script" argument and the "--" argument to indicate the end of Chimera's arguments and the start of the script's arguments, something like:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>chimera --nogui --script yourScript.py -- yourArg1 yourArg2 ...</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>You need to get the current production release candidate if you need the --script support.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>--Eric</DIV><DIV><BR><DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> Eric Pettersen</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> UCSF Computer Graphics Lab</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> <A href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</A></DIV></DIV><BR><DIV><DIV>On Nov 7, 2007, at 4:51 PM, Ryan wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">I am trying to import Chimera in a python script but get the following error message:</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Traceback (most recent call last):</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><SPAN class="Apple-converted-space"> </SPAN>File "./chimera_import.py", line 16, in <module></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><SPAN class="Apple-converted-space"> </SPAN>import chimera</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><SPAN class="Apple-converted-space"> </SPAN>File "/usr/local/chimera/share/chimera/__init__.py", line 15, in <module></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><SPAN class="Apple-converted-space"> </SPAN>from _chimera import *</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">ImportError: /usr/local/chimera/lib/_chimera.so: wrong ELF class: ELFCLASS32</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Does anyone know what the problem is here?<SPAN class="Apple-converted-space"> </SPAN>I can run Chimera without a problem in the GUI -- so i would assume that means the chimera class is being properly loaded in that instance.<SPAN class="Apple-converted-space"> </SPAN>I have the 32 bit Linux version installed on my AMD64 system running SUSE.<SPAN class="Apple-converted-space"> </SPAN>Thanks for your help,</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">ryan</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Chimera-users mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:Chimera-users@cgl.ucsf.edu">Chimera-users@cgl.ucsf.edu</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users">http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users</A></DIV> </BLOCKQUOTE></DIV><BR></DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR><DIV><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></BODY></HTML>
