pykaal

Read, plot and analyze lifetime data. Currently, it inherently supports reading data collected using Picoharp instruments.

Suports only Python >3.6.

Installation

pip install pykaal

Usage

import pykaal as kl

# Read Picoharp .phd files
p = kl.read_phd(filename)

# Get number of traces
len(p)

# General information about the data
print(p)

# Get specific traces
p.curve(0) # get the first trace

# Get trace resolution
p.res(0)

# Get time-axis for the first trace
p.t(0)

# Plot the first trace
p.plot(0)

# Plot multiple traces on a matplotlib figure
import matplotib.pyplot as plt

fig, ax = plt.subplots()

p.plot(0, ax=ax) # plot the first trace on axis 'ax'
p.plot(1, ax=ax) # plot the second trace on the same axis

# Alternatively, you can also plot the following way
plt.plot(p.t(0), p.curve(0))

# Plot traces without normalizing
p.plot(0, norm=False) # default is True

# Simple boxcar smoothening
p.smooth(0, smooth=True, boxwidth=3) # you can also specify the 'mode', refer to numpy.convolve for more info

# Plot with smoothening
p.plot(0, smooth=True, boxwidth=3)
