[MMTK] setConfiguration -> frames are not aligned

[Ralf Biehl]

Hi all

Following sequence produces an error as shown in the code below

__MMTK.__version__
 '2.5.24'
org=universe.copyConfiguration()
new=ParticleVector(universe,r_[[a.position() for a in universe.atomList()]])
org+new
.....

<type 'exceptions.ValueError'>: frames are not aligned

Same error with universe.setConfiguration and anything that needs _add_ 
the same under MMTK 2.5.23     is working

Is it a bug in 2.5.24 or do i something wrong?

Best
Ralf




code:

I[54]scatter: MMTK.__version__
       O[54]: '2.5.24'

I[55]scatter: org=universe.copyConfiguration()
I[56]scatter: new=ParticleVector(universe,r_[[a.position() for a in 
universe.atomList()]])
