agilent-format

python-agilent-file-formats

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.

Installation

The package can be installed from PyPI as:

pip install agilent-format

Usage

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']
