Molconn-Z is the standard program for generation of Molecular Connectivity, Shape, and Information Indices for Quantitative Structure Activity Relationship (QSAR) Analyses. New parameters and concepts of QSAR, including the E-State, have been introduced first in Molconn-Z. This release, in addition to being built on an all-new platform, introduces new capabilities to the Molconn-Z canon:

Unique Molconn-Z Computations in Version 4.00:

• New Group-Type counts, E-States and Hydrogen E-States.

• Improved descriptors for describing hydrogen bond donors, acceptors and internal hydrogen bonding.

• Enhanced hydrogen and non-hydrogen Atom-Type set.

• Consistent descriptor nomenclature.

The output parameters can be easily integrated into standard and advanced statistical analyses such as:

• Multiple Linear Regression
• Nonlinear Regression
• Partial Least Squares
• Discriminant Analysis
• Pattern Recognition
• Cluster Analysis
• Principal Component and Factor Analysis
