Welcome to the website for the HASH software. Here, you can download the newest version of the software, read the license agreement, or e-mail inquiries. Instructions for installing and using HASH can be found in the README file included in the distribution.

HASH is an automated program for predicting Ha chemical shifts using the chemical shifts of nearby backbone atoms (i.e., adjacent atoms in the sequence). HASH is developed in the lab of Prof. Bruce Donald at Duke University.

The current version of HASH specifically exploits the dependencies on chemical shifts of nearby backbone atoms to predict Ha chemical shifts. It combines a new fragment-based chemical shift search approach with a non-parametric regression model, called the generalized additive model, to effectively solve the prediction problem. More details about HASH can be found in our primary publications:
