The suite is available without cost to academic institutions, subject to a completed license form being returned to the CCP4 secretary; but a charge is made to commercial users who should contact the CCP4 secretary to make arrangements. Please note that all charges for the suite are used for CCP4 activities. If you intend to use the CCP4 Suite, please read the conditions in the accompanying license and return a completed copy of the license by fax or post (NOT email). If you are a for-profit organisation, then please contact the CCP4 secretary first. Thank you.
