MATBOX: Microstructure Analysis Toolbox

MATLAB open source microstructure analysis code embedded with a graphic user interface
v1.0b May 19, 2021
See release_notes.txt for a change log.

Update: February 2024
Progress toward 2.0 public release (planned for early-mid 2024)

• Microstructure generation module: done
  NEW: tube-based generation submodule (e.g. carbon nanotubes with curvature and non-overlapping)
  NEW: web-based generation submodule (e.g. PTFE fibrils)
  NEW: surface roughness generation submodule (stochastic or grains-based)
  UPDATED: ellipsoids-based stochastic particle generation submodule: faster generation and masks

• ROI, filtering and segmentation module: active development, near finished
  NEW: multiple files segmentation
  NEW: create and use macros for automated segmentation
  NEW: parallel segmentation workflows with workflow merging
  NEW: local erosion and dilation
  NEW: instance segmentation
  UPDATED: revamped GUI

• Microstructure characterization: well advanced
  NEW: TPBL for fuel cell and electrolyzer
  NEW: chord length particle size method
  UPDATED: improved RVE calculations
  UPDATED: more different type of connectivity
  UPDATED: revamped GUI

• Microstructure visualization: done
  NEW: create video animation of your 3D microstructure
  UPDATED: revamped visualization and better segmentation inspection

Some articles will be published concomitantly with the public release. Then I will work on revamping the documentation, starting with tutorial videos.

Update: March 16 2023. There has not been an update for a while. The next version is still in development, just with more changes than initially expected. If you are NREL and want to have access to the current version, please contact me (especially if you are doing characterization, as the new version of the module is much better than the one in the public repository).

What is MATBOX?

MATBOX is a MATLAB application for performing various microstructure-related tasks including microstructure numerical generation, image filtering and microstructure segmentation, microstructure characterization, three-dimensional visualization, result correlation, and microstructure meshing.
MATBOX was originally developed to analyse electrode microstructures for lithium ion batteries; however, the algorithms provided by the toolbox are widely applicable to other heterogeneous materials.

How to?

The toolbox provides a user-friendly experience thanks to a Graphic-User Interface and requires no coding to be used. Installation and instructions are detailed in the documentation. Run src/Main_menu/Main_menu.mlapp to start the toolbox (mlapp extension corresponds to MATLAB app created with app designer) and choose the module relevant for your activity.

• MATBOX main menu and illustration of each module:

• The inputs for most modules are stack tiff files (which once imported in MATLAB are 3D arrays). MATBOX modules connectivity is illustrated below:

How to contribute?

MATBOX already includes third-party open source algorithms (full list in documentation). If you wish to add algorithm(s) in MATBOX, please contact the author at francois.usseglioviretta@nrel.gov or let a message in the discussion section of this repository. All the same if you have suggestions, feedbacks, or want to report a bug.

Important notes

• I got some feedbacks from MAC users the GUI does not initialize well, while there is no issue for Windows Users. Therefore, currently Windows is recommended over other OS.
• Some modules built with app designer require MATLAB 2021a. A simple workaround is to open the mlapp file with app designer as it will automatically convert the file to your MATLAB version (but you may loss some functionnality).
• Matlab app designer does not have a consistent behavior from version to version about the GUI tab (left side of the interface). It may be truncated or not. If not truncated, it may truncate the right side of the GUI. If that happens to you, open the mlapp file with app designer and increase the width of the GUI (both the figure and the tab container). It should fix your issue.
