A UNIX/X-WINDOW program to display and assign 2D, 3D, and 4D NMR spectra. Evaluation of 3D and 4D spectra is based on the concept of "strips", i.e. parts of the spectrum the position of which is defined in a corresponding 2D spectrum. Fully compatible with DIANA/DYANA (program to calculate 3D structure from NMR restraints by Peter Güntert).

Source Code Availability:   Yes

Available Binary Packages:

  • Debian Package:   No
  • RedHat RPM Package:   No
  • Other Packages:   No

Targeted Platforms:

The program has been tested on Silicon Graphics and SUN workstations.

Software/Hardware Requirements:

XEASY is written in C to run on X-Window systems. It uses the Motif libraries, i.e. Motif must be installed. For SunOS 4.x and 5.x executables with statically linked Motif library are available, so that you may be able to run it without Motif. XEASY is extensively tested on various Sun workstations and on SGI. No basic problems are known that would prevent it from running on other UNIX systems supporting X-Window.
