PyPalmSens 2.2.0

PyPalmSens 2.2.0 is now available on PyPi.

To upgrade: pip install pypalmsens -U.

For more information, see the documentation

This release adds more methods for array and curve manipulation.

DataArray manipulation

The DataArray wrapper now supports in-place mutation via Python slice assignment, so you can overwrite values without creating a new array. Assign a sequence to a slice to replace that range. You can also assign a scalar to broadcast it across the slice.

Alternatively, use DataArray.update to replace all values at once. Both methods raise ValueError if the supplied data length does not match the DataArray.

>>> import pypalmsens as ps
>>> arr = ps.data.DataArray([0, 0, 0, 0])

# Replace the whole array in-place
>>> arr[:] = [1, 2, 3, 4]
>>> arr
[1.0, 2.0, 3.0, 4.0]

# Broadcast a scalar into a sub-range
>>> arr[1:3] = 99
>>> arr
[1.0, 99.0, 99.0, 4.0]

# Replace all values
>>> arr.update([5, 6, 7, 8])
>>> arr 
[5.0, 6.0, 7.0, 8.0]

Note if you got the data from a DataSet or Curve, the changes will propegate to the parent class as well.

DataArray arithmetic operations

• curve_a + curve_b and curve_a - curve_b now return new Curve objects
• array_a + array_b and array_a - array_b now return new DataArray objects.
• array * value now multiplies by that scalar value and returns new DataArray objects.

New methods

• DataArray.normalize: return a new DataArray with values scaled to the 0–1 range.
• Curve.concat: append another curve's x/y DataArray values onto this curve and returns a new Curve.

Exceptions submodule

PyPalmSens specific exceptions can now be accessed via pypalmsens.exceptions submodule.
