Service release

New features:

• coordinates:
  • for lag < chunksize improved speed (50%) for TICA. #960
  • new config variable "coordinates_check_output" to test for "NaN" and "inf" values in
    iterator output for every chunk. The option is disabled by default. It gives insight
    during debugging where faulty values are introduced into the pipeline. #967

Fixes:

• coordinates:
  • save_trajs, frames_from_files: fix input indices checking. #958
  • FeatureReader: fix random access iterator unitcell_lengths scaling.
    This lead to an error in conjunction with distance calculations, where
    frames are collected in a random access pattern. #968
• msm: low-level api removed (use msmtools for now, if you really need it). #550
