Currently the new analysis framework can only read trajectory files of all atoms in the tpr. Convert could produce a tpr of a subgroup, but that is messy (\#1667). Allowing reading of trajectories of part of the system should not be much work, since that just requires one extra selection with the xtc group and an index translation. *(from redmine: issue id 1861, created on 2015-11-25 by berkhess, closed on 2016-04-05)* * Relations: * relates #1667 * Changesets: * Revision 12c07b72ae96df91681320cd6312f89e864fdf8f by Teemu Murtola on 2016-01-10T12:25:09Z: ``` Support arbitrary subset trajectories in poscalc.* - Make low-level selection code work with trajectories that contain an arbitrary subset of the topology atoms, instead of just the first N. - Add an entry to t_trxframe to represent such trajectories. - Add some basic tests. Negative cases crash with an assert, so not tested (should get caught higher up). This should cover all of selection evaluation, but various consistency checks need to be adjusted as well (will be done in a child change). Related to #1861.
