In GENEAcore: Pre-Processing of 'GENEActiv' Data

GENEAcore 1.1.2

New features

• Added overloads for get_UniqueBinFileIdentifier() to enable it to also read a filename or a directory path

GENEAcore 1.1.1

New features

• The StepDiff measure is now included in outputs as default when output_steps = TRUE
• Create a bin file summary from geneacore() by passing parameter summary = TRUE
• geneacore() can now take either a path to a directory of bin files or a path to a single bin file
• MPI file_history now records parameters passed during function calls
• MPI now records the GENEAcore package version used during execution
• A new MPI is created if package version is not listed in the existing MPI
• New DateTimeUTC column has been added to the events and epochs CSV files
• Button press (event marker) timestamps are now recorded in the MPI
• A new MPI is created when a version number does

Minor improvements

• Removed warning message when MPI already exists
• Warning messages added for deprecated functions

Bug fixes

• geneacore() steps error resolved when there are not enough events in the day
• geneacore() events are created when a day has only a single transition (when non-wear spans across multiple days)

GENEAcore 1.1.0

New features

• detect_nonmovement() uses a new sd_threshold value
• detect_transitions() uses new default changepoint penalty values
• apply_all() function applies AGSA, ENMO, UpDown and Degrees measures in a single function
• detect_transitions() runs changepoint only if a different 24-hour cut time is set
• sample_binfile() has new parameter option to allow raw sample RDS to be saved
• detect_transitions() removes short changeover transition between days
• Partial epochs are removed from aggregation output
• Aggregated events and epochs output have added day index column and AGSA.sd and ENMO.sd columns have been removed
• Standardised format of start time and duration for still bouts and non-wear bouts
• Certainty field removed from non-wear bouts
• MPI reports first and last timestamps as integer values

Minor improvements

• sample_binfile() outputs an improved message with time zone offset when reading subset of file

Bug fixes

• detect_transitions() now applies a minimum 5 seconds of data for a valid day
• Event start time and transitions timestamps now match

Breaking changes

• Updated naming conventions for MPI outputs, parameters and functions, see breaking-changes.html
