Software Releases

Strain Matrix Labeler
This is a free source code of a software that can visualize and add label to strain matrix data. It is developed in Python using PyQt, Numpy and Matplotlib.
Distributed at: https://github.com/jr-xing/strainmatLabeler
Role: Developer

FLASHC Docker Image
This is a docker image that has FLASH (a C++ implementation for fast diffeomorphic image registration algorithm) installed. Instead of configuring a series of C++ libraries and facing the risk of messing up the system, with the docker image user can simply download and use in a plug-and-play manner.
