SIMMOL is a flexible tool for visualization and definition of NMR interaction tensors in macromolecular structures. So, if you have problems setting up the spin system for your SIMPSON simulations you benefit from using SIMMOL. SIMMOL is released as part of SIMPSON.
shAIC predicts chemical shifts accurately for proteins based on their structure using a statistical approach summing local and long-range contributions applying Akaikes Information Criterion to optimally parameterize the method.
ASICS guides you through all steps in assignment, analysis, and presentation of single-crystal NMR data.
FFM - Fast Forward Maximum Entropy - is a program for reconstruction of nonuniformly sampled datasets. Relies on the FM algorithm but is several orders of magnitude faster.
We wish to share the Tcl-libraries we have been developing, mainly for use with SIMPSON or in VMD. Some of the libraries are written entirely in Tcl and are thus platform independent and do not need compilation. Others are written in C and needs be compiled after download.
