previously there was a global "default header" object which each OpatIO table used to build off of. The issue was that this did a shallow copy so if there were multiple OpatIO objects instantiated they would all modify the same header object. This has been resolved by moving the default header to a function which generates it fresh for each OpatIO object.
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 opaticy 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")
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])
