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
