[Versioning]#

0.minor.patch.postN

  • .minor : Introduces new features and may include potential breaking changes. Any breaking changes will be explicitly noted in the changelog (e.g., new functions or parameters, changes in parameter defaults, or function names).

  • .patch : Contains fixes for identified bugs and may include modifications or added parameters for improvements/enhancements. All fixes and modifications are backwards compatible.

  • .postN : Consists of documentation changes or metadata-related updates, such as modifications to type hints.

[0.23.3] - 2025-03-08#

✨ Enhancement#

  • Improved error handling for custom parcel approaches. The structure of the sub-keys are validated to prevent errors due to incorrect structure down the pipeline.

[0.23.2] - 2025-03-06#

♻ Changed#

  • Minor improvements to str call for clarity.

  • Added optional dependencies for benchmarking and cleaned repeating optional dependencies.

  • Created separate static internal function for computing cosine similarity between the 1D region mask and high/low amplitude of the CAP vector.

[0.23.1] - 2025-02-27#

♻ Changed#

  • Minor improvements in how run IDs are intersected to prevent errors in rare cases.

  • Update confound names in test datasets to thier modern counterparts in fMRIPrep.

🐛 Fixes#

  • Added pytest-cov and pre-commit as optional dependencies

  • Fix case in version 0.23.0 when confound_names is None but n_acompcor_separate is specified, which resulted in the no acompcor components being included for nuisance regression.

  • Also, add warning is no cosine regressors are included in confound_names but the following is detected:

    • n_acompcor_separate specified

    • "a_comp_cor" or "t_comp_cor" included in confound_names

[0.23.0] - 2025-02-25#

  • Updates pertain to TimeseriesExtractor

🚀 New/Added#

  • Added a new key to fd_threshold for optional cubic spline interpolation of censored volumes not at the beginning or end of the timeseries and is only done after nuisance regression and parcellation. By default, interpolation is not done and must explicitly be set to True.

♻ Changed#

  • Default for confounds_names changed from None to "basic". The "basic" option now performs the same functionality as confound_names=None did in previous versions.

  • Ordering of some self.signal_clean_info parameters changed.

🐛 Fixes#

  • Raises ValueError when use_confounds=False but fd_threshold, n_acompcor_separate, or ``dummy_scans = {"auto": True} is specified. IMPORTANT:

  • Fixed issue that occured only when n_acompcor_separate is None (default), which resulted in all acompcor regressors are selected from the confounds metadata due to list slicing issue [0:None]. Not an issue when n_acompcor_separate is not None or the preproccesing pipeline directory did not have a confounds json file. FIX: The confounds metadata is only retrieved when n_acompcor_separate is not None.

  • Overall improved error handling.

[0.22.2] - 2025-02-21#

🚀 New/Added#

  • Added new "exceptions" module containing the BIDSQueryError.

📖 Documentation#

  • BIDSQueryError now documented.

  • Updated doc strings to redirect to documentation about directory structure/entities.

[0.22.1.post0] - 2025-02-19#

📖 Documentation#

  • Add clarifying information to doc strings about the entities/file naming structure.

[0.22.1] - 2025-02-18#

♻ Changed#

  • More efficient computation of transition probability

[0.22.0.post0] - 2025-02-17#

📖 Documentation#

  • Add clarifying information to docs.

[0.22.0] - 2025-02-17#

♻ Changed#

  • Change in internal logic for condition to not add plus one to the duration scan index (scans = range(start, end + 1) -> scans = range(start, end)) to reduce potential condition spillover in certain task designs such as rapid events.

📖 Documentation#

  • Remove version change directives under 0.19.0 to clean up docs.

[0.21.8] - 2025-02-13#

🚀 New/Added#

  • CAP and TimeseriesExtractor classes now have defined string dunder methods that return specific metadata.

[0.21.7] - 2025-02-11#

🐛 Fixes#

  • Fixed documentation rendering issues in VSCode.

📖 Documentation#

  • Cleaned documentation in some functions.

[0.21.6] - 2025-02-06#

🐛 Fixes#

  • CAP.outer_products property now no longer returns None when it is not None.

[0.21.5] - 2025-01-27#

🚀 New/Added#

  • Added new progress_bar parameter to CAP.calculate_metrics, CAP.caps2niftis, CAP.caps2surf, CAP.get_caps, and TimeseriesExtractor.get_bold to display tqdm progress bars.

📖 Documentation#

  • Cleans version change/version added directives and references for versions under 0.19.0 to clean up documentation.

  • Additional minor documentation cleaning.

[0.21.4] - 2025-01-24#

🐛 Fixes#

  • Fix issue in "counts" computation in CAP.calculate_metrics for case where no TRs are assigned to a specific label/CAP. Instead of "counts" being 0 in this case, it would be a 1. Issue did not affect the other metrics ("temporal fraction", "persistence", etc), which would correctly be 0 in such cases.

[0.21.3] - 2025-01-17#

🐛 Fixes#

  • Added ipywidgets in optional dependencies for a better experience with the "openneuro_demo" Jupyter notebook.

[0.21.2] - 2025-01-14#

🐛 Fixes#

  • Fixes warning about ignoring mandatory keys in fd_threshold and dummy_scans.

  • Also adds check to ensure that the "outlier_percentage" key is a float between 0 and 1.

  • Setuptools version pinned to 64.0 or greater.

[0.21.1] - 2025-01-10#

🐛 Fixes#

  • Better type validation for fd_threshold and dummy_scans.

📖 Documentation#

  • Slightly clearer documentation on the criteria used for fd_threshold.

[0.21.0] - 2025-01-02#

  • Added a new parameter, slice_time_ref in TimeseriesExtractor.get_bold to allow onset to be subtracted by slice_time_ref * tr if desired.

[0.20.0] - 2024-12-31#

🚀 New/Added#

  • Added new log message specifying the condition being extracted if condition is not None.

  • Added a new parameter, condition_tr_shift in TimeseriesExtractor.get_bold to allow a shift in the the starting and ending scan in TR units for a condition.

[0.19.4] - 2024-12-24#

📖 Documentation#

  • Links are fixed in the documentation.

🐛 Fixes#

  • Fix indexing error for visualize_bold if parcel_approach["Custom"]["nodes"] is a NumPy array instead of list.

♻ Changed#

  • Internally, the verbose parameter is set to 0 for nilearn's fetch_atlas_aal and fetch_atlas_schaefer. and the behavior is stated in the documentation. Cosine similarity in this case is assigned np.nan

  • When creating "regions" for the "Custom" parcel approach, both a list and range can be accepted. Previously, only lists were accepted.

[0.19.3.post0] - 2024-12-10#

📖 Documentation#

  • Additional documentation for standardize function.

[0.19.3] - 2024-12-08#

🚀 New/Added#

  • Method chaining for several methods in the CAP and TimeseriesExtractor class.

[0.19.2] - 2024-12-06#

🐛 Fixes#

  • Add type hints to properties.

  • Improve accuracy of type hints for the properties.

  • Fixes type hints for certain parameters that included numpy.ndarray.

  • Replaces any returns that implies a plot object is returned and replaces with None for clarity.

  • Raise type error when self.subject_table in CAP is set but is not a dictionary.

[0.19.1] - 2024-11-30#

  • Primarily to ensure all the latest distributions have the correct documentation links.

  • Includes some internal code changes that won't change results.

  • TODO for future version is to support Python 3.13.

[0.19.0] - 2024-11-28#

  • Cleaning some of the API, specifically parameter names and properties, no defaults have been changed in this update.

API for 0.18.0 versions

API for 0.19.0

🚀 New/Added#

  • suffix_filename added to CAP.caps2plot, CAP.caps2surf, CAP.caps2radar, and transition_matrix. This addition was done to allow the suffix_title parameter in each of the previously listed methods to only be responsible for the title of the plots. The suffix filename will also be appended to the end of the default filename.

  • CAP class now has a cluster_scores property to consolodate the inertia, davies_bouldin, silhouette, and "variance_ratio" scores into a property instead of separate properties. Consequently, the inertia, davies_bouldin, silhouette, and "variance_ratio" have been removed.

The structure of this property is:

{
    "Cluster_Selection_Method": str,  # e.g., "elbow", "davies_bouldin", "silhouette", or "variance_ratio"
    "Scores": {
        "GroupName": {
            2: float,  # Score for 2 clusters
            3: float,  # Score for 3 clusters
            4: float,  # Score for 4 clusters
        },
    }
}

♻ Changed#

  • Any instance of file_name in a parameter name has been changed to the more conventional parameter name filename. For instance, suffix_file_name now becomes suffix_filename and file_names becomes filenames. This change effects the following functions: merge_dicts, standardize, change_dtypes, CAP.calculate_metrics, CAP.caps2niftis, TimeseriesExtractor.timeseries_to_pickle, and TimeseriesExtractor.visualize_bold.

  • Warning logged whenever file name parameter is used but output_dir is not specified.

📖 Documentation#

  • Fix doc parameter error for CAP.caps2niftis that used suffix_title instead of suffix_file_name, which is now suffix_filename.

  • In documentation, version labels restricted to changes or additions make from 0.18.0 and above for less clutter.
