Python library for reading FT-IR imaging datasets created by Resolutions Pro on Agilent Cary instruments with FPA area detectors.
Port of https://bitbucket.org/AlexHenderson/agilent-file-formats/ to Python
Developed for use in the orange-spectroscopy add-in, which is part of the Quasar data analysis program.
The package can be installed from PyPI as:
pip install agilent-format
There are four primary classes for loading data, depending on the type:
| Class | Data Type | Extension |
|---|---|---|
agilentImage |
Single-tile FPA image | .dat |
agilentMosaic |
Mosaic FPA image | .dmt |
agilentImageIFG |
Single-tile interferograms | .seq |
agilentMosaicIFG |
Mosaic interferograms | .dmt |
To use, load the corresponding data loader class with the appropriate filename:
from agilent_format import agilentImage
ai = agilentImage("agilent_format/datasets/4_noimage_agg256.dat")
ai.data # 3-dimensional numpy array (height x width x wavenumbers)
ai.wavenumbers # list of wavenumbers in order of .data array
# Pixel size can be calculated by:
px_size = ai.info['FPA Pixel Size'] * ai.info['PixelAggregationSize']
