Error getting MinMover attributes

[Anonymous]

Hi,

I’m experiencing some very strange behavior on part of PyRosetta.

I’m running pre-built PyRosetta v2.011 for ScientificLinux (64 bit, r47657) on Linux 3.0.3 ( x86_64) with Python 2.6.6. I’ll use MinMover as an example, but this happens with many other object types.

I can instantiate, configure and run a MinMover without a hitch, e.g. min_mover.tolerance(0.025) works fine. But when I try to access that information using a getter, i.e. min_mover.tolerance(), I get an ArgumentError.

Here’s the output from my iPython session:

In [1]: import rosetta



In [2]: rosetta.init()

PYROSETTA_DATABASE environment variable was set to: /vol/ek/share/csbw/tools/pyrosetta/rosetta_database... using it...

MinMover doesn’t have a getter tolerance(). At least, it doesn’t in trunk C++, SVN 47908. Is this a general answer to the missing functions?

I committed the path that add accessor methods, so builds for versions 48154+ will have it.

Thanks for your (insanely) quick reply, Steven. Saved me some time and agony.

Regarding generality, I don’t know how common this issue is among Rosetta objects. If it’s widespread, then IMHO objects missing basic getters *is* an issue (think debugging, or interactive PyRosetta).

Thanks, Sergey. I’m checking out the PyRosetta.develop dir right now.

Was that a specific oversight in MinMover, or a reoccurring theme?

I would guess our general getter-and-setter co-coverage is about 75%. I would guess the coverage of internal data that SHOULD be exposed via getters and setters (as opposed to only being available via constructor) is something like 33%. These are wild guesses…

They’re generally easy to write if you want to attack the problem!
