opatio 0.1

A python module for handling OPAT files

opatIO python module

This module defines a set of tools to build, write, and read OPAT files. The OPAT fileformat is a custom file format designed to efficiently store opacity information for a variety of compositions.

Installation

You can install this module with pip

git clone <repo>
cd 4DSSE/utils/opat
pip install .

General Usage

The general way that this module is mean to be used is to first build a schema for the opacity table and then save that to disk. The module will handle all the byte aligment and lookup table construction for you.

A simple example might look like the following

from opatio import OpatIO

opacityFile = OpatIO()
opacityFile.set_comment("This is a sample opacity file")
opaticyFile.set_source("OPLIB")

# some code to get a logR, logT, and logKappa table
# where logKappa is of size (n,m) if logR is size n and
# logT is size m

opacityFile.add_table((X, Z), logR, logT, logKappa)
opacityFile.save("opacity.opat")
opaticyFile.save_as_ascii("opacity.txt")

You can also read opat files which have been generated with the loadOpat function

from opatio import loadOpat

opacityFile = loadOpat("opacity.opat")

print(opacityFile.header)
print(opaticyFile.tables[0])
