lumicks.pylake.fdcurve.FdCurve

class FdCurve(file, start, stop, name, force='2', distance='1')

An FD curve exported from Bluelake

By default, the primary force and distance channels are downsampled_force2 and distance1. Alternatives can be selected using FdCurve.with_channels(). Note that it does not modify the FD curve in place but returns a copy.

Attributes:

file : lumicks.pylake.File

The parent file. Used to look up channel data.

start, stop : int

The time range (ns) of this FD curve within the file.

name : str

The name of this FD curve as it appeared in the timeline.

__init__(file, start, stop, name, force='2', distance='1')

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(file, start, stop, name[, force, …])	Initialize self.
distance_range_selector([show, max_gap])
from_dataset(h5py_dset, file, **kwargs)
plot_scatter(**kwargs)	Plot the FD curve points
range_selector([show])
with_baseline_corrected_x()	Return a copy of this F,d curve with baseline correction applied to force channel.
with_channels(force, distance)	Return a copy of this FD curve with difference primary force and distance channels
with_offset([force_offset, distance_offset])	Add a constant force offset from the force data in this F,d curve.

Attributes

d	The primary distance channel associated with this FD curve

downsampled_force1x
downsampled_force1y
downsampled_force2
downsampled_force2x
downsampled_force2y

downsampled_force3x
downsampled_force3y
downsampled_force4
downsampled_force4x
downsampled_force4y
f	The primary force channel associated with this FD curve

plot_scatter(**kwargs)

Plot the FD curve points

Parameters:

**kwargs

Forwarded to ~matplotlib.pyplot.scatter.

with_baseline_corrected_x()

Return a copy of this F,d curve with baseline correction applied to force channel. Note: only the x component is available with baseline correction. Note: All previous data manipulations (eg. subtraction of another curve) will be lost.

with_channels(force, distance)

Return a copy of this FD curve with difference primary force and distance channels

with_offset(force_offset=0, distance_offset=0)

Add a constant force offset from the force data in this F,d curve. Note that points where the distance is defined as zero are ignored and that subtracting a distance offset bigger than the minimum distance in the F,d curve will result in an error.

Parameters:

force_offset : float

distance_offset : float

d

The primary distance channel associated with this FD curve

f

The primary force channel associated with this FD curve
