[ccp4bb] [Fwd: [ccp4bb] accessible surface area of PISA at EBI]
Dear all, I understood what they mean. ASA -> Solvent accessible surface area BSA -> Buried area among Solvent accessible surface area when it make interaction Sorry for self-questioning and -answering.

[ccp4bb] accessible surface area of PISA at EBI
Dear all, Could you explain two terms of "Accessible Surface Area"(ASA) and "Buried Surface Area"(BSA) of PISA at EBI ? I thought that Standard accessible surface area = Solvent accessible surface area + Buried surface area. When I looked up the result of PISA, ASA is always bigger than BSA except "inaccessible residues". Thus, I think that ASA of PISA means that "Standard accessible surface area" but one weird thing is that those values of same type residues,i.e. Ala, are quite varied among one chain. Also, "Inaccessible residues" has 0.00 square angstrom for both ASA and BSA. How can this happen? I believe that ASA should be bigger than 0.00, for instance, 100 angstrom square.

Re: [ccp4bb] ARP_wARP 7.0 release
Hi Tracy - Thats actually a warning message (sorry to use the word error there ...) and it should not stop the program from running. I believe, you dont have to take any action. If the procedure however stops indeed, please send us detailed log files and more complete output to try and solve it. Thanks for the bug report - Tassos On 17 Jul 2007, at 19:48, Tracy Arakaki wrote: Hello, I just tried running the new version of ARP/wARP (Classic) and got the following error message: :1: parser error : Document is empty XMLOutputFilename = 'snow_log.xml' ^ snow - WRNG* : CConfig::processStream File isn't in proper XML format Any ideas on how to fix this so that ARP/wARP will successfully run?

[ccp4bb] MrBUMP version 0.4.0 release
Dear All, We're pleased to announce the latest release of MrBUMP. Pre-release version 0.4.0 is now available from the MrBUMP website: http://www.ccp4.ac.uk/MrBUMP The new features include: - The inclusion of the new CCP4i DBviewer, a graphical interface for viewing CCP4i jobs. This will form part of the upcoming 6.1 release of CCP4. We are grateful to Wanjuan (Wendy)Yang and Peter Briggs for letting us include it in MrBUMP. - Support for installing the scripts on Windows. - Removed the requirement for inputting an MTZ file when running in "Model generation only" mode. Sequence file is all that is required now. Kind regards, Ronan and Martyn

[ccp4bb] aspherical atom refinement against F and F^2
Dear all: I am working on the aspherical atom refinement of a small molecule using the XD package. The program provides you with the option of selecting a refinement strategy against F or F^2. I have noticed that the R-factors and GOFs calculated based on F^2 are larger in magnitude compared to those computed based on F. Why is it so? Any comments or suggestions in this regard is welcome. Sincerely, Tuhin. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
