+# MATLAB requirements
+leverjs and ljsctc projects require matlab 2021b or later, with the database and image processing toolboxes installed.
 # using the LJSCTC repo
 
 LJSCTC can be provided via prebuilt executable for specific tasks like running a CTC dataset. this is generally how we proceed for CTC submissions. a runtime matching the version of matlab that the executable was built with is all that is required. we also utilize cuda-based image processing toolkit called the 'hydra image processor', https://git-bioimage.coe.drexel.edu/opensource/hydra-image-processor.
