GraSPI is a tool for morphology analysis. The first application was in the field of organic solar cells, where morphology affect the final performance of device. GraSPI helped us to quantify various morphological features. However, GraSPI can be used for any other application, assuming that descriptor used in GraSPI are physically relevant. We decided to share to code
See documentaion
GraSPI computes the set of descriptors/features that can used for data analytics (e.g., to establish process-structure-property maps). GraSPI is implemented in C++ and uses bash as a scripting tool to encode basic analysis pipelines. GraSPI aims to handle multiple input formats, and tools to convert various formats it to internal data structures.
GraSPI requires boost library. To compile go to src file, you find there Makefile. If you install boost library in location that is not searchable, you need to explicity provide the path.

We keep updating GraSPI, here we log the major changes:
- June 2020, the first release of GraSPI, with the capabilities to analyze two phase morphology
If you want to some additional features, send us email - see Contact info at the bottom. Here, we will keep the list of requests that we plan to introduce, and our planned extensions.
GraSPI has been developing at two institutions:
- Olga Wodo, University at Buffalo
- Baskar Ganapathysubramian, Iowa State Univiersity
Any questions and queries can be directed to Olga: olgawodo at buffalo dot edu.
