r25942 | bugman | 2014-09-22 09:59:35 +0200 (Mon, 22 Sep 2014) | 6 lines
Created the Structure.test_collapse_ensemble system test.
This is used to test a planned feature of the internal structural object.
The collapse_ensemble()
method will be created to remove all but one model in the structural ensemble.
........
r25943 | bugman | 2014-09-22 10:14:25 +0200 (Mon, 22 Sep 2014) | 5 lines
Fixes for the structure.add_atom user function to allow for list of lists for
the atomic position.
This allows different coordinates to be supplied for each model.
........
r25944 | bugman | 2014-09-22 10:16:35 +0200 (Mon, 22 Sep 2014) | 5 lines
Modified the Structure.test_collapse_ensemble system test to check the
initial values.
This is for sanity reasons as the test coverage of the structure.add_atom
user function is poor.
........
r25945 | bugman | 2014-09-22 10:29:55 +0200 (Mon, 22 Sep 2014) | 5 lines
Implemented the internal structural object collapse_ensemble() method.
This allows the Structure.test_collapse_ensemble system test to pass.
