CCP4 Software Licence PREAMBLE The purpose of this document is to state the terms and conditions under which the CCP4 Program Suite software and documentation as defined at Annex 1 ("the CCP4 suite") may be used. NOTICE TO USER: BY USING THE SOFTWARE YOU ACCEPT THE FOLLOWING TERMS AND CONDITIONS WHICH APPLY TO ITS USE. 1. The CCP4 Suite is compiled at Daresbury Laboratory with support from the Biotechnology and Biological Sciences Research Council (BBSRC) of the UK as part of the Collaborative Computational Project Number 4 (CCP4), on Protein Crystallography, first set up in October 1979. 2. Any opinion, findings, conclusions or recommendations expressed in the CCP4 program suite are those of the authors/contributors and do not necessarily reflect the views of the BBSRC. 3. The CCP4 suite is in part the property of the Council for the Central Laboratory of the Research Councils ("CCLRC"). Additionally extra modules may be supplied which are not specifically owned by the Council. These may be the copyright of a third party and are distributed under terms, which as far as the Council is aware, permit them to be included within the terms of this Licence. If this is so this notification or declaration that the information is in the public domain will be included in the files. The Council shall, in all good faith, distribute these modules in compliance with the terms and conditions as set down by the third party. The Council shall not be liable and shall take no responsibility for any module that is not the property of the Council. 4. The CCP4 suite is made available free of charge for use by non-profit educational, academic and research institutions. However, as the distribution of the CCP4 suite can prove to be an expensive commitment, non-profit institutions requiring versions to be distributed on magnetic tape or disk may be asked to pay for the time and media involved. No recipient of the CCP4 suite and or material shall offer magnetic tapes, microfiche, listings or any further CCP4 item for sale as a commercial item. 5. For items of the CCP4 suite considered as being of Part (i) (Annex 1), (and for items considered as Part (ii) (Annex 1) of the CCP4 distribution that do not have an explicit statement of warranty then the following warranty statement also applies) these are supplied under the following conditions:- i) The CCP4 suite is provided to the user "as is" and neither CCLRC nor the original authors/contributors make any warranty as to its use, performance or results which the user may obtain by using the CCP4 suite. CCLRC makes no warranties, express or implied, as to non-infringement of third party rights, merchantability, or fitness for any particular purpose. In no event will CCLRC or original authors/contributors be liable to the user for any consequential, incidental or special damages, including any lost profits or lost savings, even if a CCLRC representative or original authors/contributors has been advised of such damages, or for any claim by any third party. 6. For items of the CCP4 suite considered as being Part (ii) and Part (iii) (Annex 1), if the authors have given a statement of copyright and warranties then those notices apply to those items of the CCP4 suite. 7. As part of CCP4's two goals of preserving the free status of all of our free software (and derivatives), and of promoting the sharing and reuse of software generally, then for items of software considered as being of part (i) (Annex 1), the CCP4 library routines, you are permitted and encouraged to use, copy, modify and distribute this software and its documentation for any purpose and without fee. A notice to 'CCP4/Daresbury Laboratory' must appear in all copies, and the User must do the following: (a) cause the modified files to carry prominent notices stating that you changed the files and the date of any change, and to provide those changes back to the community; (b) for the whole of any work that you distribute or publish, that in whole or in part contains the Part (i) (Annex 1) routines or any part thereof, either with or without modifications, then any subsequent licence that you charge to all third parties must exclude the CCP4 Part (i) (Annex 1) software and such Part (i) (Annex 1) software can only be included under the terms of this Conditions of Distribution (except that you may choose to grant warranty protection to some or all third parties, at your option). 8. For a single site that requires more than one implementation of the CCP4 distribution the User may copy verbatim copies of the CCP4 distribution as they receive it, in any medium at that site, provided that the User conspicuously and appropriately publishes on each copy an appropriate copyright notice and disclaimer of warranty. 9. The User may not copy, modify, sublicence, distribute or transfer the CCP4 suite except as expressly provided under either this agreement or as in the case of the CCP4 suite considered as either Part (ii) or Part (iii) (Annex 1) by the Copyright notices of the original authors. Any attempt otherwise to copy, modify, sublicence, distribute or transfer the CCP4 suite is void, and will automatically terminate your rights to use the CCP4 suite under this Agreement. 10. Neither the CCLRC nor the original authors are under any obligation to maintain the CCP4 suite nor to respond to requests for information from the User. 11. The provision of any version of the CCP4 suite under the terms and conditions specified herein does not imply that future versions will also be made available under the same terms and conditions. 12. For any publication arising from use of the CCP4 program suite, a reference to (Collaborative Computational Project, Number 4, 1994) should be given as: COLLABORATIVE COMPUTATIONAL PROJECT, NUMBER 4, 1994. "The CCP4 Suite: Programs for Protein Crystallography". Acta Cryst. D50, 760-763. along with any additional references, required by the original authors, pertaining to individual programs where the use of the programs contributed to an investigation. 13. The CCP4 suite (with respect to this license agreement) will be used solely at the following address: Name ___________________________________ Address ___________________________________ ___________________________________ ___________________________________ Telephone ___________________________________ Fax __________________________________________ E-mail ___________________________________ I have read the CCP4 Software Licence (including Annex 1) and I agree to uphold the terms and conditions of this licence: Name ____________________ Signed ____________________ Position ____________________ Date ____________________ Under the terms of the UK's DATA PROTECTION ACT 1984, we are obliged to notify you that you are on a CCP4 mailing list and that your name and address are held on computer. The Act requires your consent to your name and address being so held. Our receipt of this completed form will indicate your acceptance. ANNEX 1 The CCP4 Program Suite consists of three parts: i) The set of Library routines for the handling of MAP files, MTZ files and PDB files and the general routines for DISKIO, CCPLIB, (parts of) MODLIB, FFTLIB, PLOT84LIB, SYMLIB, CCIFLIB, HARVLIB, LIBHTML, should be regarded as 'Free-Software', with Copyright still remaining with the original authors and/or their place of employment where that software was written as employees in the course of their employment, and is freely available from CCP4 and the BBSRC. This software is held in the subdirectories src and ccif in: CCP4_MASTER: [CCP4.LIB] (for the VMS distribution), %CCP4_MASTER%\ccp4\lib (for DOS based systems), and $CCP4_MASTER/ccp4/lib (for the Unix distribution). ii) Contributed programs which use the part (i) library routines. For this set of software all copyrights remain with the original authors of the code. If a Part (ii) program does not contain a Copyright notice then this Copyright notice applies. Examples of this software are held in directories: VMS: CCP4_MASTER: [CCP4.SRC]; DOS: %CCP4_MASTER%\ccp4\src; Unix: $CCP4_MASTER/ccp4/src iii) Other independent works which have been merely aggregated to the CCP4 distribution media, where the Advisory Notices and/or Copyright Notices for this other work allow for the free distribution of that code. This set of software (or their derivatives) that are held on the CCP4 volume of storage or distribution medium are not brought under the scope of the terms of the CCP4 distribution conditions. Examples of this software are held in the directories: VMS Unix $CCP4_MASTER:[XTAL.WULFF] $CCP4_MASTER/wulff $CCP4_MASTER:[XTAL.LAUE] $CCP4_MASTER/laue The distribution tape and ftp area contains copies of all programs in the CCP4 suite (source code) plus documentation and shell files for running the programs interactively.
