PyCaF

Automated experimentation along with data analysis with Python

This repository contains Python code for data analysis tasks using popular libraries like Pandas, NumPy, and Matplotlib. The purpose of this project is to showcase different data analysis techniques and provide examples that can be used as a reference.

Getting Started

To get started, install anaconda in your system.

Clone this repository

git clone https://github.com/ColdMatter/pycaf.git

Then create a new environment using the command

conda create -f environment.yml

After creating the environment activate the environment using

conda activate pycaf

Navigate to the pycaf directory

cd \your_path\pycaf

Here install pycaf in editable mode using the command:

pip install -e .

Dependencies

The main libraries used in this project are:

  • Pythonnet: Used for the python to C# bridge.
  • NumPy: Used for numerical computing.
  • Matplotlib: Used for creating visualizations.
  • Plotly: Used for better interactive visualization.

Contributing

If you find any issues or have suggestions for improvements, feel free to open an issue or submit a pull request. Contributions are welcome and encouraged!

Example api usage

Create the experiment and probe object

import numpy as np
import datetime
import pycaf

today = datetime.date.today()
config_path = "C:\\ControlPrograms\\pycaf\\config_bec.json"

expt = pycaf.Experiment(config_path=config_path, interval=0.1)
probe = pycaf.Probe(config_path, today.year, today.month, today.day)

Run an experimet

expt.scan(
    script="MOTBasic",
    motmaster_parameters_with_values={
        "yagONorOFF": [10.0, 1.0]
    },
    lasers_with_frequencies={
        "v00": np.arange(494.431850, 494.431880, 0.000003).tolist()
    },
    n_iter=10
)

Analyse the experimental data

probe.number_by_image(
    0, 10, "CameraTriggerStart",
    row_start=40, row_end=70,
    col_start=40, col_end=70,
    xscale=1e-2,
    yscale=1.0,
    xlabel="CameraTriggerStart [ms]",
    ylabel="Molecule number",
    display_images=True,
    grid=False,
    show_roi=False
)
