 # Pore2Chip: All-in-One Python Tool for Soil Microstructure Analysis and Micromodel Design
 
 ## What is Pore2Chip?
-Pore2Chip is a Python module designed to streamline the process of analyzing X-ray computed tomography (XCT) images of soil and creating 2D micromodel designs based on that analysis. It leverages the power of open-source libraries like OpenPNM, PoreSpy, and drawsvg to  extract key information about the soil's porous structure and translate it into a blueprint for microfluidic simulations or physical "lab-on-a-chip" devices developed using additive manufacturing.

 # Summary
 
 The `Pore2Chip` Python package is designed to create 2D micromodels using extracted data from 3D X-ray computed tomography 
-(XCT) images. This package helps analyze soil structure and function, allowing for the investigation of environmentally significant biogeochemical processes 
-that impact soil organic matter (SOM) decomposition and loss, oxygen concentrations, and nutrient availability in disturbed or managed soils. Key metrics encompass pore size 
-distributions, pore throat size distributions, and connectivity (pore coordination numbers). The final output is a 2D scalable SVG 
-design representing a core or aggregate. Designs can be fabricated with methods such as laser etching, 3D printing, and photolithography.

 # Statement of need
 
-The resilience of agricultural and natural landscapes is intrinsically connected to soil structure. Land management (e.g., tillage, grazing, and fire) and 
-associated impacts (e.g., compaction and pore-clogging) along with climate disturbances (e.g., freeze-thaw, flooding, and sea level rise) can transform soil 
-microstructure [@Stoof2016; @Liu2018; @Feng2020; @deOliveira2022; @Rooney2022]. These changes in the soil microstructure 
-determine the flow of water, solutes, and gasses as well as SOM retention, transport, and distribution 
-[@hamamoto2010excluded; @bailey2017differences; @Waring2020]. Simplified, homogeneous pore networks provide innovative 
-demonstrations of how water, solutes, and microbes interact [@Bhattacharjee2022] but need more accurate representations of soil properties.

 Creating realistic heterogeneous habitats is time-consuming and does not include pore network characteristics, such as pore 
-connectivity. Incorporating pore dynamics into soil models such as SOM degradation enables dynamic predictions for soil 
+connectivity. 
+Incorporating pore dynamics into soil models such as chemical species degradation enables dynamic predictions for soil 
 responses under changing pore networks [@davidson2012d; @moyano2018diffusion].
 
-The need for software that can generate various micromodel designs that researchers can test and validate with minimal computational 
-cost [@Dentz2023; @Oostrom2014] is increasing. `Pore2Chip` allows this functionality by providing the intended users, such as earth scientists and 
-lab-on-chip instrument specialists, with easy-to-use research software for lab-on-chip designs. Specifically, the Pore2Chip-based data worth analysis allows researchers to 
-fill this experimental design gap by enabling the ability to build a representative quasi-2D pore network along with 
-first-order, fast, and reasonably accurate flow models that can be linked with experiments. These flow models are built using recent advances in 
-physics-informed neural networks [@New2024], laying the foundation to accelerate numerical simulations and improve the fidelity of predictions in 
-microscale environments. Moreover, `Pore2Chip` allows one to assess the impact of various system parameters, such as pore structures, fluid properties, and 
-flow conditions, needed to develop optimal micromodel experiments. Such a capability can guide model-experiment-data (ModEx) integration at the microscale, 
-allowing for upscaling microscale processes and predictions of dynamic soil properties and functions (see \autoref{fig:fig1}).

 ## Main features and differences with other tools
 
 `Pore2Chip` addresses complex pore structures by representing pore networks as connected shapes, unlike older sphere packing algorithms. 
-This enables users to easily create and control pore networks representing various real-world conditions. `Pore2Chip` offers experimental design capabilities that 
-cannot be achieved by existing software such as epyc [@Dobson2022]. 
-`Pore2Chip` provides support and reproducibility for developing lab-on-chip experimental designs uniformly across different soil datasets with fast, reasonably 
-accurate, first-order flow modeling capabilities. Microscale experiments using `Pore2Chip` micromodels may target both abiotic and biotic 
-processes and be integrated into modeling efforts such as water flow modeling, reactive transport modeling, and microbial activity simulations.

 ## Implementation details and support libraries
 
 Using `Porespy` [@Gostick2016], `OpenPNM` [@Gostick2016] and various graphics rendering libraries (e.g., drawsvg, ezdxf, svglib, cairosvg, reportlab), 
-`Pore2Chip` renders SVG or DXF micromodel designs of the generated network. Output designs are scalable and adjustable based 
-on the target porosity of the micromodel. It can also be exported as micromodel data in VTK formats for 
-visualization in Paraview or microfluidic simulations with open-source software such as `PFLOTRAN` (https://www.pflotran.org), `OpenFOAM` (https://www.openfoam.com), 
-and other physics-informed neural network modules. If the user wants to extract data from XCT images, `Pore2Chip` has image filtering and network extraction 
-modules utilizing Otsu thresholding and `PoreSpy`. The generation function can also work with data extracted by other means if it is an array of values that 
-Python can read.
