Astrolabe Python Library

• Astrolabe_py contains scripts and modules to:
  • Check FITS file metadata for validity,
  • Show FITS file HDU information,
  • Upload FITS files to iRods, optionally extracting FITS metadata and attaching it to the uploaded files in iRods.

Installation

Install via PyPi

pip install astrolabe-py

Python Build using Conda

Building this software requires Python 3.6+. Assuming you have Conda installed, you can use it to build this project within a virtual environment:

git clone https://github.com/AstrolabeProject/astrolabe_py.git
source activate
conda create -n alpy python=3.6
conda activate alpy
cd astrolabe_py
pip install -r requirements.txt

Running Tests

The tests can be run manually from the test subdirectory, as follows:

cd test
python fits_ops_test.py
python fits_meta_test.py
python irods_help_test.py
python uploader_test.py

Running the Uploader Script

Uploader Script Options:

usage: uploader [-h] [-v] [-u] [--version] [--keyfile [metadata-keyfile]] images_path

FITS file metadata extraction and upload of a file or directory of files.

positional arguments:
   images_path           path to a FITS file or a directory of FITS files to be processed

optional arguments:
   -h, --help            show this help message and exit
   -v, --verbose         provide more information during execution
   -u, --upload-only     upload files to iRods only: do not process file metadata
   --version             show program's version number and exit
   --keyfile [metadata-keyfile]
                         a file specifying which metadata keys which should be processed

Examples:

uploader -v myDataDirectory
uploader --upload-only myImages/someImage.fits
uploader --keyfile just-these-keys.txt astrofiles

Running the Checker Script

Checker Script Options:

usage: checker [-h] [-a {check,info}] [-v] [--version] images_path

Perform verification actions on a FITS file or a directory of FITS files OR
Show HDU info for the specified FITS file or directory of FITS files

positional arguments:
  images_path           path to a FITS file or a directory of FITS files to be processed

optional arguments:
  -h, --help            show this help message and exit
  -a {check,info}, --action {check,info}
                        action to perform on FITS file(s): validate or show HDU info
  --version             show program's version number and exit

Examples:

checker myDataDirectory
checker -a check myDataDirectory

checker myImages/someImage.fits
checker -a check myImages/someImage.fits

checker -a info myDataDirectory
checker -a info myImages/someImage.fits
