aftpy 1.1.0

Python package to read and download AFTmap data.

AFTpy

The Python package enables users to download, visualize, and analyze AFT HDF (h5) data seamlessly. AFTPy offers a comprehensive solution for analyzing and downloading Advective Flux Transport (AFT) data, streamlining the process of data downloading in parallel and also facilitating the conversion of H5 files into the most popular FITS file format or various other formats with ease.

Installation

From PyPI

pip install aftpy

From source

git clone [e-mail]:bibhuraushan/aftpy.git
cd aftpy
python setup.py install

Discriptions

aftpy provides two importent python module named aftmap and aftgetdata. These modules can be used to read the single aftmap file or load all the files from a given directory.

aftmap module

aftmap modules also provides two python class AFTmap and AFTload. The AFTmap class provide an interface to read the singale H5 AFTmap file and provide you the functions and isntances to get the information and plot the data. The other class AFTload provides the interface to load all the data from a directory and provide the instances and function to know about the loaded data. It also provides a function to convert all the loaded data in to popular FITS file.

AFTmap Class

AFTload Class

A class for loading all AFT maps from directory.

Attributes

• path (str): The path to the directory containing AFT map files.
• filetype (str): The file extension of the AFT map files (e.g., "h5").
• date_fmt (str): The date format string used to parse timestamps from filenames.
• filelist (list): A list of file paths to AFT map files in the specified directory.
• filenames (numpy.ndarray): An array of filenames extracted from the filelist.

Methods

• convert_all(convert_to="fits", outpath=".", verbose=True) Convert all loaded AFT map files to the specified format.
  • convert_to (str, optional): The output format to convert the AFT map files to. Defaults to "fits".
  • outpath (str, optional): The directory path to save the converted files. Defaults to current directory.
  • verbose (bool, optional): Whether to print conversion progress. Defaults to True.

Example Usage

import aftpy.aftmap as aft

# Initialize AFTload object
loader = aft.AFTload(path="/path/to/aft/maps", filetype="h5")

# Convert all AFT map files to FITS format to '/path/to/converted/maps'
loader.convert_all(convert_to="fits", outpath="/path/to/converted/maps", verbose=True)

aftgetdata module

AFTdownlaod Clas

A class for downloading AFT map files from a specified URL.

Attributes

• ncpu (int): Number of CPU cores to utilize for downloading files. Defaults to cpu_count() - 1.
• dt (module): Alias for the datetime module.
• root_url (str): The root URL from where AFT map files will be downloaded. Defaults to "https://data.boulder.swri.edu/lisa/".
• urls (list): List of URLs of AFT map files.
• datafile (str): File path to store the list of files in CSV format.
• datalist (DataFrame): DataFrame containing the list of files and corresponding timestamps.

Methods

• get_list(t0=None, t1=None, dt=1) -> data (DataFrame)

  • t0 (datetime.datetime, optional): Start time of the time range. Defaults to None.
  • t1 (datetime.datetime, optional): End time of the time range. Defaults to None.
  • dt (int, optional): Time interval for sampling files within the time range. Defaults to 1.
  • Returns data (DataFrame): DataFrame containing the list of files within the specified time range.

• reload_files(url=None, filetype="h5") Reload the list of AFT map files from the root URL.

  • url (str, optional): The URL to reload the list of files from. Defaults to None.
  • filetype (str, optional): The file extension of AFT map files. Defaults to "h5".
  • Returns: True if the list of files is successfully reloaded.

• download(dataframe, rootpath=None, ncpu=None) Download AFT map files listed in the DataFrame.

  • dataframe (DataFrame): DataFrame containing the list of files to download.
  • rootpath (str, optional): Root directory path to save the downloaded files. Defaults to None.
  • ncpu (int, optional): Number of CPU cores to utilize for downloading files. Defaults to cpu_count() - 1.

Example Usage

import aftpy.getaftdata as aftget
# Initialize AFTdownload object
downloader = aftget.AFTdownload()

# Reload the list of AFT map files
downloader.reload_files()

# Get the list of AFT map files within a specified time range
file_list = downloader.get_list(t0=dt.datetime(2023, 1, 1), t1=dt.datetime(2023, 1, 7))

# Download AFT map files listed in the DataFrame
downloader.download(file_list)
