lost my paths
by Keren Lasker 03 Feb '09

03 Feb '09

hi, A recent change in r1369 (imppy.sh no longer propagates external LD_LIBRARY_FLAGS and PYTHONPATH) breaks Frido and my assembler code since our pythonpath contains more than just IMP. Can someone please take a look? thanks, Keren.

Given we already have rotation from_fixed_xyz which is a form of euler angles, this function should probably have a more descriptive name describing which Euler angles it uses.

Moving Movers to Containers
by Daniel Russel 02 Feb '09

02 Feb '09

As part of the gradual move to using containers, I would like to move the Mover classes (NormalMover and BallMover) to use the container classes. The visible change would be that they would take a non-optional SingletonContainer as the first argument of the constructor instead of an optional list of particles as the last argument. Any reasons not to?

hey, Reading either the attached files I get: File "../../../utils/transform_mol.py", line 7, in <module> mp= IMP.modeller.read_pdb(sys.argv[1],m) File "/viola1/home/kerenl/bioinformatics/projects/imp/build/lib/IMP/ modeller/__init__.py", line 460, in read_pdb hcp.add_child(hrp) File "/viola1/home/kerenl/bioinformatics/projects/imp/build/lib/IMP/ core/__init__.py", line 1985, in add_child def add_child(*args): return _IMP_core.MolecularHierarchyDecorator_add_child(*args) RuntimeError: Bad key index File "build/include/IMP/internal/AttributeTable.h", line 245 any clue why ? thanks, Keren.
