Unreleased

v0.5 – 2026-02-10

Added

The datahandling package brings a completely new data importing interface:
- The generic storage format of the Luna ODiSI 610x series (.dat files) is now suported.
- Arbitrary large measurement files are supported. The files can now be read chunkwise, which removes the previous limit that the complete data needed to fit into RAM.
- Objects for reading measurement files (filereader) and requesting data (filehandler) are now separated.
- New function datahandling.tsvutils.tsv_print_metadata_table() to quickly get an overview over the content a bunch of TSV in a given directory.

Deprecated

protocols is deprecated and superseded by the datahandling package with the filereader and filehandler modules.
Moved function protocols.extract_time_intervals() to datahandling.tsvutils.tsv_extract_time_intervals().

v0.4.2 – 2026-01-23

Added

New function protocols.extract_time_intervals() to extract time interval partitions of measurement data to smaller .tsv files.

Fixed

Minor fixes in documentation
Fix Unicode warnings for Python 3.13

v0.4.1 – 2025-04-21

Added

Add Coding Style Guide for contributers

Fixed

Fix bug in GTM, where strain reading anomalies in the last element of an array are not detected
Fixes in documentation and continuous documentation deployment

v0.4 – 2024-11-20

This version adds substantial improvements for data preprocessing. The way to clean up raw data got completely overhauled.

Added

Add continuous deployment for public documentation
Introduced new workflow for preprocessing:
- New workflow class for preprocessing: preprocessing.Preprocessing
- New module preprocessing.Filtering for noise reduction
- New module preprocessing.Masking for removal of SRAs introducing new SRA detection algorithms:
  - preprocessing.masking.GTM
  - preprocessing.masking.OSCP
  - preprocessing.masking.ZscoreOutlierDetection
- New module preprocessing.Repair for removal of dropouts:
  - preprocessing.repair.ScipyInterpolation1D for replacing dropouts with interpolated data
- New module preprocessing.Resizing for changing data shape with new options:
  - Aggregate
  - Crop
  - Downsampling
  - Resampling
utils.interpolation.scipy_interpolate1d: interpolation wrapper function around scipy functionality
New functions utils.misc.datetime_to_timestamp() and utils.misc.timestamp_to_datetime()
protocols.ODiSI6100TSVFile:
- New method .get_data() for data retrieval
- Option to read tsv header data (metadata, gages/segments, tare, x-axis) only
Add a dictionary-like interface to crackmonitoring.crack.Crack, not set attributes are now always reported as None
More methods for CrackList:
- get_cracks_by_location() supersedes the removed CrackList.get_crack()
- get_cracks_attribute_by_range(),
- get_cracks_attribute_is_none(),
- clear_attribute()
Documentation is built continuously and hosted publicly on GitHub.

Changed

utils.cropping.cropping() is now a standalone function
preprocessing.resizing.Crop works as a preset wrapper for utils.cropping.cropping()
Filter and Repair objects now require both x-data and y-data
Renamed fosutils.find_next_neighbor() → fosutils.next_finite_neighbor()
Generalized the functionality and versatility of preprocessing.filtering.SlidingFilter, making preprocessing.filtering.SlidingMean and preprocessing.filtering.SlidingMedian obsolete
protocols.ODiSI6100TSVFile.get_time_series: Change return order form (time_stamps, time_series, x_value) to (x_value, time_stamps, time_series) for consistency with other data retrival methods

Fixed

protocols.ODiSI6100TSVFile.read_file() will now skip blank lines instead of crashing

Removed

preprocessing.strip_smooth_crop() was replaced a new more powerful interface.
protocols.ODiSI6100TSVFile.get_mean_over_y_record(), the two components of the function got separated: Firstly, use protocols.ODiSI6100TSVFile.get_data() for easy data selection. Secondly, the consolidation is now done by a preprocessing.resizing.Aggregate object.
Preprocessing functionalities and clean up some unused attributes from strainprofile.StrainProfile
preprocessing.filtering.SlidingMean and preprocessing.filtering.SlidingMedian, functionality is now in preprocessing.filtering.SlidingFilter
Ability of ODiSI6100TSVFile to read multiple files, only one file will be supported
CrackList.get_crack(), superseded by CrackList.get_cracks_by_location()

v0.3 – 2023-11-13

Added

New sub-packages for compensation and preprocessing and moved functionality there
ODiSI6100TSVFile can import both full .tsv files, gage .tsv files or both into the same object now
Sliding filters and possibility to chain filters
Changelog introduced
fosutils.find_next_finite_neighbor()
The project is now packaged on PyPI.
Cute logo

Changed

Renamed properties of cracks.Crack to be more descriptive
Imports are now relative, wherever possible.
The tension stiffening formula reworked
Inheritance of classes in protocol
cracks.CrackList.get_crack() now returns the nearest crack by default.
crop.Crop now treats 2D arrays as well.
Refactored integration.Integrator
Transfer length default limits are now the strain minimum or 0.2 m (whatever is closer to the crack).
Renamed protocols.ODiSI6100TSVFile.header → protocols.ODiSI6100TSVFile.metadata
Updated tutorial

Fixed

Several issues
generatedemofile.py now should produce correct content

Deprecated

preprocessing.strip_smooth_crop() function will be replaced by a new preprocessing workflow in the next version.
protcols.Strainprofile.get_mean_over_y_record() function will be replaced by a new preprocessing workflow in the next version.
