LinearTransform Class

class flowkit.transforms.LinearTransform(transform_id, param_t, param_a)

Parametrized linear transformation, implemented as defined in the GatingML 2.0 specification:

flin(x, T, A) = (x + A) / (T + A)

Parameters:

  • transform_id – A string identifying the transform

  • param_t – parameter for the top of the linear scale (e.g. 262144)

  • param_a – parameter for the offset, controls the bottom of the scale

apply(events)

Apply transform to given events.

Parameters:

events – NumPy array of FCS event data

Returns:

NumPy array of transformed events

inverse(events)

Apply the inverse transform to given events.

Parameters:

events – NumPy array of FCS event data

Returns:

NumPy array of inversely transformed events
