Reporting a problem to CCP4

Online problem reporting and CCP4bb posting suspended

The facility to report problems or post to CCP4bb from a webform has unfortunately been suspended. This is due to technical problems with the underlying technology, and CCP4 wishes to apologise for any inconvenience that this may cause our users. We hope to be able to restore the service in the near future.

In the meantime we can still be contacted the old-fashioned way via email at the address ccp4@ccp4.ac.uk.

If you are reporting problems with using CCP4 software

Please first check the relevant problems pages. If this does not help then please send as much information as you can to help CCP4 staff identify and fix the problem - typically we will need to know the following:

Please send this information to us at ccp4@ccp4.ac.uk. To understand why we ask for all this information, you might like to read this article.

If you wish to post to CCP4bb

At present you will need to send any postings directly to ccp4bb@dl.ac.uk. Note that you will first need to be correctly subscribed to the list; details can be found on the CCP4bb page.

Apologies for the inconvenience that the suspension of these services may cause, and thanks for your patience.
