  • Updated coverage workflow, report separate unit vs integration coverage. @rly #1509
  • Deleted test files generated from running sphinx gallery examples. @rly #1517
  • Enabled passing an S3File created through s3fs, which provides a method for reading an NWB file directly from s3 that is an alternative to ros3. This required relaxing of NWBHDF5IO input validation. The path arg is not needed if file is provided. mode now has a default value of "r". @bendichter #1499
  • Added a method to NWBMixin that only raises an error when a check is violated on instance creation, otherwise throws a warning when reading from a file.

  • Add testing/mock, which provides mock neurodata objects for testing. @bendichter #1454

PyNWB 2.1.0 (July 6, 2022)

Breaking changes:

  • Updated TimeIntervals to use the new TimeSeriesReferenceVectorData type. This does not alter the overall structure of TimeIntervals in a major way aside from changing the value of the neurodata_type attribute of the TimeIntervals.timeseries column from VectorData to TimeSeriesReferenceVectorData. This change facilitates creating common functionality around TimeSeriesReferenceVectorData. For NWB files with version 2.4.0 and earlier, the TimeIntervals.timeseries column is automatically migrated on read in the TimeIntervalsMap object mapper class to use the TimeSeriesReferenceVectorData container class, so that users are presented a consistent API for existing and new files. This change affects all existing TimeIntervals tables e.g., NBWFile.epochs, NWBFile.trials, and NWBFile.invalid_times. While this is technically a breaking change, the impact user codes should be minimal as this change primarily adds functionality while the overall behavior of the API is largely consistent with existing behavior. @oruebel, @rly (#1390)

Enhancements and minor changes

  • A warning is now raised if SpatialSeries.data has more than 3 columns. @bendichter, @rly (#1455, #1480)
  • The arguments x, y, z, imp, location, filtering are no longer required in the electrodes table. @h-mayorquin, @rly (#1448)
  • Added cell_id attribute to IntracellularElectrode. @bendichter (#1459)
  • Added offset field to TimeSeries and its subtypes. @codycbakerphd (#1424)
  • Added support for NWB 2.5.0.
    • Added support for updated IndexSeries type, new order_of_images field in Images, and new neurodata_type ImageReferences. @rly (#1483)
  • Added support for HDMF 3.3.1. This is now the minimum version of HDMF supported. Importantly, HDMF 3.3 introduces warnings when the constructor of a class mapped to an HDMF-common data type or an autogenerated data type class is passed positional arguments instead of all keyword arguments. @rly (#1484)
  • Moved logic that checks the 0th dimension of TimeSeries data equals the length of timestamps to a private method in the TimeSeries class. This is to avoid raising a warning when an ImageSeries is used with external file. @weiglszonja (#1486)
  • Improved warning text when dimensions are not matched in TimeSeries, ElectricalSeries, and RoiResponseSeries. @rly (#1491)

Documentation and tutorial enhancements:

  • Added tutorial on annotating data via TimeIntervals. @oruebel (#1390)
  • Added copy button to code blocks. @weiglszonja (#1460)
  • Created behavioral tutorial. @weiglszonja (#1464)
  • Enhanced display of icephys pandas tutorial by using dataframe_image to render and display large tables as images. @oruebel (#1469)
  • Created tutorial about reading and exploring an existing NWBFile. @weiglszonja (#1453)
  • Added new logo for PyNWB. @oruebel (#1461)
  • Minor text fixes. @oruebel @bendichter (#1443, #1462, #1463, #1466, #1472, #1473)

Bug fixes:

  • Fixed input data types to allow only float for fields conversion and offset in definition of TimeSeries. @codycbakerphd (#1424)

  • Added checks for data orientation in TimeSeries, ElectricalSeries, and RoiResponseSeries @bendichter (#1428)
  • Added checks for data orientation in TimeSeries, ElectricalSeries, and RoiResponseSeries. @bendichter (#1426)
  • Enhanced issue template forms on GitHub. @CodyCBakerPHD (#1434)

PyNWB 2.0.0 (August 13, 2021)

Breaking changes:

  • SweepTable has been deprecated in favor of the new icephys metadata tables. Use of SweepTable is still possible but no longer recommended. @oruebel (#1349)
  • TimeSeries.__init__ now requires the data argument because the 'data' dataset is required by the schema. If a TimeSeries is read without a value for data, it will be set to a default value. For most TimeSeries, this is a 1-dimensional empty array with dtype uint8. For ImageSeries and DecompositionSeries, this is a 3-dimensional empty array with dtype uint8. @rly (#1274)
  • TimeSeries.__init__ now requires the unit argument because the 'unit' attribute is required by the schema. If a TimeSeries is read without a value for unit, it will be set to a default value. For most TimeSeries, this is "unknown". For IndexSeries, this is "N/A" according to the NWB 2.4.0 schema. @rly (#1274)

New features:

  • Added new intracellular electrophysiology hierarchical table structure from ndx-icephys-meta to NWB core. This includes the new types TimeSeriesReferenceVectorData, IntracellularRecordingsTable, SimultaneousRecordingsTable, SequentialRecordingsTable, RepetitionsTable and ExperimentalConditionsTable as well as corresponding updates to NWBFile to support interaction with the new tables. @oruebel (#1349)
  • Added support for NWB 2.4.0. See Release Notes for more details. @oruebel, @rly (#1349)
  • Dropped Python 3.6 support, added Python 3.9 support. @rly (#1377)
  • Updated requirements to allow compatibility with HDMF 3 and h5py 3. @rly (#1377)
    • When using HDMF 3 and h5py 3, users can now stream NWB files from an S3 bucket.

Tutorial enhancements:

  • Added new tutorial for intracellular electrophysiology to describe the use of the new metadata tables and declared the previous tutorial using SweepTable as deprecated. @oruebel (#1349)
  • Added new tutorial for querying intracellular electrophysiology metadata (docs/gallery/domain/plot_icephys_pandas.py). @oruebel (#1349, #1383)
  • Added thumbnails for tutorials to improve presentation of online docs. @oruebel (#1349)
  • Used sphinx.ext.extlinks extension in docs to simplify linking to common targets. @oruebel (#1349)
  • Created new section for advanced I/O tutorials and moved parallel I/O tutorial to its own file. @oruebel (#1349)
  • Overhauled documentation on extensions. @bendichter, @rly, @oruebel (#1350)
  • Updated the optical physiology / Calcium imaging tutorial. @bendichter, @weiglszonja (#1375)
  • Added a tutorial on streaming using the ROS3 driver. @rly (#1393)

Minor new features:

  • Added RRID for citing PyNWB to the docs. @oruebel (#1372)
  • Updated CI and tests to handle deprecations in libraries. @rly (#1377)
  • Added test utilities for icephys (pynwb.testing.icephys_testutils) to ease creation of test data for tests and tutorials. @oruebel (#1349, #1383)
  • Added on-push and nightly tests of streaming using the ROS3 driver. @rly (#1393)
  • Improve documentation and test for CorrectedImageStack, MotionCorrection. @rly, @bendichter (#1306, #1374)

Bug fixes:

  • Updated behavior of make clean command for docs to ensure tutorial files are cleaned up. @oruebel (#1349)
  • Enforced electrode ID uniqueness during insertion into table. @CodyCBakerPhD (#1344)
  • Fixed integration tests with invalid test data that will be caught by future hdmf validator version. @dsleiter, @rly (#1366, #1376)
  • Fixed build warnings in docs. @oruebel (#1380)
  • Fix intersphinx links in docs for numpy. @oruebel (#1386)
  • Previously, the data argument was required in OpticalSeries.__init__ even though external_file could be provided in place of data. OpticalSeries.__init__ now makes data optional. However, this has the side effect of moving the position of data to later in the argument list, which may break code that relies on positional arguments for OpticalSeries.__init__. @rly (#1274)
  • Fixed setup.py not being able to import versioneer when installing in an embedded Python environment. @ikhramts (#1395)
  • Removed broken option to validate against a given namespace file and updated associated documentation. @rly (#1397)

PyNWB 1.5.1 (May 24, 2021)

Bug fixes:

  • Raise minimum version of pandas from 0.23 to 1.0.5 to be compatible with numpy 1.20, and raise minimum version of HDMF to use the corresponding change in HDMF. @rly (#1363)

    • Fix issue where dependencies of included types were not being loaded in namespaces / extensions.
    • Add HDF5IO.get_namespaces(path=path, file=file) method which returns a dict of namespace name mapped to the namespace version (the largest one if there are multiple) for each namespace cached in the given HDF5 file.
    • Add methods for automatic creation of MultiContainerInterface classes.
    • Add ability to specify a custom class for new columns to a DynamicTable that are not VectorData, DynamicTableRegion, or VocabData using DynamicTable.__columns__ or DynamicTable.add_column(...).
    • Add support for creating and specifying multi-index columns in a DynamicTable using add_column(...).
    • Add capability to add a row to a column after IO.
    • Add method AbstractContainer.get_fields_conf.
    • Add functionality for storing external resource references.
    • Add method hdmf.utils.get_docval_macro to get a tuple of the current values for a docval_macro, e.g., 'array_data' and 'scalar_data'.
    • DynamicTable can be automatically generated using get_class. Now the HDMF API can read files with extensions that contain a DynamicTable without needing to import the extension first.
    • Add EnumData type for storing data that comes from a fixed set of values.
    • Add AlignedDynamicTable type which defines a DynamicTable that supports storing a collection of subtables.
    • Allow np.bool_ as a valid bool dtype when validating.
    • See https://github.com/hdmf-dev/hdmf/releases for full HDMF release notes.

PyNWB 1.4.0 (August 12, 2020)

Users can now add/remove containers from a written NWB file and export the modified NWBFile to a new file path. @rly (#1280)

Compatibility warnings:

  • PyNWB no longer works with HDMF version < 2.1.0. If you have pinned HDMF version < 2 in your package but allow PyNWB version 1.4.0, please beware that pip may install PyNWB version 1.4.0 with an incompatible version of HDMF (version < 2).
  • Use of HDMF 2.1.0 fixes __getitem__-based access of MultiContainerInterface types, e.g,, fluorescence['roi_response_series_name'], where previously if the MultiContainerInterface contained only one item, then any key could be used within the square brackets to access the contained Container, even if the key did not match the name of the contained Container. This update patches this bug such that the key used within the square brackets must match the name of the contained Container or else an error will be raised.

Internal improvements:

  • Update requirements to use HDMF 2.1.0. @rly (#1256)
  • Start FAQ section in documentation. @rly (#1249)
