v0.6.0

What’s new

Feature highlights

• Convert negative increment CSDM object to positive increment CSDM object.
• Accepts both C and F contiguous numpy array to convert to CSDM object. #57
• Add csdm.reshape(dim1, dim2) to CSDM object to reshape a CSDM object to the
  given list dimension object---dim1, dim2.
• Numpy broadcasing mulipllication can now be applied to csdm objects.
• Support for additional numpy methods np.pad and np.flip.

Bugfix

• fft and ifft scale the first point by 2 when the dimension is non-periodic.
• Bugfix in serializing csdm #54
• You can multiply CSDM objects by a scalar to the right (csdm * scalar). The fix
  now allows the multiplication of CSDM objects by a scalar to the left (scalar * csdm). #62
• Bugfix where csdm objects .csdfe files were immutable.

Full Changelog: v0.5.0...v0.6.0

v0.5.0

What’s new

• Add support for np.cumsum, np.cumprod, np.argmin, and np.argmax functions to CSDM objects.

Bugfix

• Bugfix involving plot of CSDM datasets with dependent-variable quantity type of vector_1 or pixel_1.
• Bugfix when assigning DimensionList/DependentVariableList to the CSDM dimensions and dependent_variables attributes, respectively. #45
• Bugfix in CSDM object serializing when using Astropy.units v4.0 and higher.
• Bugfix for incorrect class name. #39

Deprecated

• add_x, and add_y functions of the CSDM object are removed.

v0.4.1

Patch update for the CSDM dimension's quantity_name attribute value from units compatible with astropy>=4.3

v0.4.0

The csdmpy package is a Python support for the core scientific dataset (CSD) model file exchange-format. The package is based on the core scientific dataset (CSD) model which is designed as a building block in the development of a more sophisticated portable scientific dataset file standard. The CSD model is capable of handling a wide variety of scientific datasets both within and across disciplinary fields.

What's new

• The add_dimension and add_dependent_variable from CSDM class are deprecated.

Bugfix

• Fixed error in calculating the nmr dimensionless frequency ratio (ppm) when dimension.complex_fft=False

v0.3.4

The csdmpy package is a Python support for the core scientific dataset (CSD) model file exchange-format. The package is based on the core scientific dataset (CSD) model which is designed as a building block in the development of a more sophisticated portable scientific dataset file standard. The CSD model is capable of handling a wide variety of scientific datasets both within and across disciplinary fields.

v0.3.3

The csdmpy package is a Python support for the core scientific dataset (CSD) model file exchange-format. The package is based on the core scientific dataset (CSD) model which is designed as a building block in the development of a more sophisticated portable scientific dataset file standard. The CSD model is capable of handling a wide variety of scientific datasets both within and across disciplinary fields.

v0.3.2

Bug fixes

• Bugfix in fft method when applied to multi-dimensional CSDM objects.

Others

• Added new tutorial examples.

v0.3.1

Bug fixes

• Bugfix regarding the phase multiplier for the CSDM.fft() methods where an incorrect phase was multiplied to the signal vector.

v0.3.0

Whats new!

Support for matplotlib.pyplot functions from CSDM objects. The following functions are supported
- plot,
- scatter,
- imshow,
- contour, and
- contourf

Now you can directly plot CSDM objects as an argument to the above matplotlib methods by creating Matplotlib axes with projection='csdm'

import Matplotlib.pyplot as pat
ax = plt.subplot(projection='csdm')
# ax.plot()  # not plot as you would with matplotlib functions.
plt.show()

csdmpy

v0.2.2

Bug fixes

• Fixed bug where the metadata from the csdm.application key was not serialized
  to the file when using csdm.save() method.

Other changes

• Add a new diffusion tensor MRI dataset to the example gallery.
• Added dict() as an alias to the to_dict() method for all objects.
• Added an alias of the cp.plot() function to the CSDM object as the
  plot() method.
