[IMP-dev] IMP::display::CMMWriter

[Davide Baù <>]

Hi, 

I have some problem in understanding how the new writers work.

I'm using the CMMwriter like, writing out only the final model (frame):

# Setup a CMM writer

writer = IMP.display.CMMWriter("model.%1%.cmm")

log = IMP.display.WriteOptimizerState(writer)

g = IMP.display.XYZRsGeometry(ps)

log.add_geometry(g)

log.update()

This generates the model file with the coordinates (each line is a chimera marker) and a file called "model.%1%.cmm", which only contains the header line:

<marker_set name="model.0.cmm">

This header should be in the model file, but since it is missing it causes a problem with chimera. Is there a way to get rid of the model.%1%.cmm file so that to have just one file containing all the informations? I've tried without the %1% string:

writer = IMP.display.CMMWriter("model.1.cmm")

but that rises the error:

e = o.do_optimize(steps)

  File "/usr/src/imp/trunk/build/lib/IMP/core/__init__.py", line 4338, in do_optimize

    return _IMP_core.MonteCarlo_do_optimize(self, *args)

_IMP.InternalException: Cannot set frame on writer without file name pattern.

Thanks,

Davide
