There have been some informal discussions with the Dunbrack lab about allowing redistribution in this case, but nothing has happened so far.</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>If the 2011 library has the exact same layout as the 2002 library then there’s some hope that a non-expert Chimera programmer could incorporate the library themselves. The 2011 library would need files corresponding to the backbone-dependent 2002 file (bbdep02.May.sortlib) and independent file (bbind02.May.lib) and <i class="">in the exact same format </i>(or at least a very similar format). Otherwise the conversion would be pretty challenging. My hazy recollection of looking at the 2011 library was that this wasn’t the case, but I could be mis-remembering.</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>If the 2011 library is similar enough, the basic outline of what would need to be done is:</div><div class=""><br class=""></div><div class="">1) Pull the Chimera source code from our svn repository, so that you can access the Python library-processing scripts that aren’t included in the app distribution.</div><div class="">2) Use slightly-modified versions of the prepdeplib.py and prepindlib.py scripts in Rotamers/Dunbrack to create dependentRotamerData.zip and independentRotamerData.zip files.</div><div class="">3) Create a new subdirectory of Rotamers (Dunbrack11?) to hold these files along with an __init__.py that would be very similar to Dunbrack/__init__.py</div><div class="">4) Modify Rotamers/__init__.py to register the new library with Chimera.</div><div class=""><br class=""></div><div class="">You can see that even the “easy” conversion is a fair bit of effort. If the library formats aren’t similar, then you probably need a Python expert to modify the prep***lib.py scripts to process the 2011 library files into the corresponding zip files.</div><div class=""><br class=""></div><div class="">—Eric</div><div class=""><br class=""><div class=""><br class=""><div class="">
