SPSCAN is a new program to support semi-automatic assignment of NMR spectra of biological macromolecules. The program was initially developed in the laboratory of Prof. Kurt Wüthrich at ETH Zürich under grant Gl 237/1-1 of the Deutsche Forschungsgemeinschaft.
SPSCAN can be used together with XEASY (Ch. Bartels, T.-H. Xia, M. Billeter, P. Güntert and K. Wüthrich (1995) The program XEASY for computer-supported NMR spectral analysis of biological macromolecules. J. Biomolecular NMR 5, 1-10) - input and output formats are compatible. SPSCAN also reads spectra in NMRPipe and Bruker (2rr, 3rrr) formats. All output is compatible with DYANA.

SPSCAN is the recommended program to:

For these problems the tools and routines have been well tested. However, SPSCAN provides much more than that.


The manual on the server in Jena describes the latest test release of SPSCAN. It may contain features that are not yet in the "official" release. A matching html-manual is included in each release for local access.

The user manual for Release 1.0.53 (without development documentation) is available on the server in Zürich.


Executables (Release 1.0.53) for Sun OS 2.x and SGI are now available for external users who accept the license conditions. The program is free of charge for academic use. The program is not public domain.

Installation is very simple, but currently the program is only available for SunOS 5.x, IRIX 6.x, and Linux. Source code will be made available after publication of the program.

To get access to the program send an email to rwg@molebio.uni-jena.de with the following:

If you install SPSCAN for your group, you have to inform all members of the group in a suitable way about the license conditions.

notice to local users (Beutenberg)

The latest version for IRIX 6.x is available on disteli as "/home/disteli/rwg/bin/spscan". It does not run on IRIX 5.x.
Consider that for integration and peak picking the computer should have enough memory to hold the relevant part of the spectrum in the RAM with 4 byte/pixel. On SGI's you should start spscan always with the full path to avoid crashes with "assertion failed in ..."
