SimpleDIVA App

This app allows the user to apply a simplified version of the DIVA model to data collected from auditory sensorimotor adaptation or reflexive perturbation experiments. Specifically, the app takes as input one or more spreadsheets (csv format) containing perturbation values and subject data. The software then finds optimal fit values for key DIVA model parameters. The model’s fit to the data is then displayed, and statistics for the fit are provided. The resulting parameter values provide a mechanistic interpretation of the experimental data.

Instructions for installing and using SimpleDIVA can be found here.

NOTE: The current version of SimpleDIVA requires Matlab Runtime 2022a, a free software package that will be downloaded and installed on your computer (~3 GB of disk space) during the SimpleDIVA installation process. If Matlab Runtime 2022a is not already on your computer, you must be connected to the internet during installation of SimpleDIVA. If you are having installation issues related to Matlab Runtime, please try downloading Matlab Runtime 2022a manually from the MathWorks website: https://www.mathworks.com/products/compiler/matlab-runtime.html

Current version [Version 2.0, March 3 2023]

Version 2.0 adds the ability to fit responses to reflexive perturbations in addition to adaptive perturbations. This version also removes the baseline phase data from RMSE, correlation coefficient, and AIC calculations. The manual for version 2.0 can be found here.
