MDAnalysisData.CG_fiber.fetch_CG_fiber(data_home=None, download_if_missing=True)[source]

Load the CG fiber self-assembly trajectory

Parameters
  • data_home (optional, default: None) – Specify another download and cache folder for the datasets. By default all MDAnalysisData data is stored in ‘~/MDAnalysis_data’ subfolders. This dataset is stored in <data_home>/CG_fiber.

  • download_if_missing (optional, default=True) – If False, raise a IOError if the data is not locally available instead of trying to download the data from the source site.

Returns

  • dataset (dict-like object with the following attributes:)

  • dataset.topology (filename) – Filename of the topology file

  • dataset.trajectory (filename) – Filename of the trajectory file

  • dataset.DESCR (string) – Description of the trajectory.

See CG fiber dataset for description.
