CYANA

Combined assignment and dynamics algorithm for NMR applications

CYANA (© by Peter Güntert) is a program for automated structure calculation of biological macromolecules on the basis of conformational constraints from NMR. The combination of automated NOESY cross peak assignment, structure calculation with a fast torsion angle dynamics algorithm, and the ease-of-use of CYANA provide for unprecedented efficiency in NMR protein structure determination.

System requirements for CYANA 2.1

• CYANA 2.1 has been tested on recent versions of the following operating systems and binaries are available for these:
  • Linux (Ubuntu, CentOS)
  • MacOS (Intel and Apple Silicon processors)
  • Windows (using Windows Subsystem for Linux, WSL, with Ubuntu Linux)
• For compilation: Intel Fortran compiler or gfortran
• For parallel calculations on distributed-memory systems: OpenMPI

How to Purchase

To obtain a CYANA software license, please follow these steps:

1, Download the License form file for CYANA 2.1.

• The License form files are followings:
  academic [PDF:17KB] For an academic user: an individual or a single research group.
  commercial [PDF:15KB] For a commercial user: mainly for private companies.
  


• An academic user should not use the software for any purpose (research or otherwise) supported by a "for profit" or military organization.


• Organizations, e.g. computer centers, that will give access to the software to more than one academic research group need a special license. All other users need a Commercial License.


• Licenses include the source code, are unlimited in time.


• Licenses can be used simultaneously on any number of computer systems at the site of the licensee.

2, Print and fill out the License form(Type or clearly print).

• The completed and duly signed form and your purchase order form can be sent by email to support@las.jp
  
  

3, We will send the invoice by e-mail.

The prices are as follows:

Software Licenses	Prices
Academic License	700 Euro
Commercial License	15,000 Euro



• The acceptable method of payment is wire transfer by pay in EURO. Do not accept Credit Card and Check.


• Do not change in other foreign currency. If you are not able to pay in EURO, please contact us.


• Please pay the bank's charges, taxes if any, on Applicant. Price of a tax refund like VAT cannot be performed.

4, Upon receipt of the payment, we will e-mail you the ID and password for login to the CYANA download site.

• It takes about two weeks or more to issue the license after the wire transfer.


• The current version is CYANA 2.1 released in July 2005. The upgrade from earlier Cyana (not Dyana) versions is free-of-charge. If you are interested in the upgrade, please contact us.
