Re: [ccp4bb] Requesting old data sets

Dear Juergen, That's a practically important approach to recheck the details of structures. I refined from the structure factor files of two published structures related to my subject and already found some key information that was missing in the published ones. So it would be more confident i

The star is usually for sugar atoms, not for the bases. I don't remember what curves wants. Does your PDB have apostrophes instead of stars? If so you should just do a global search and replace. If you still have a problem, you should copy-paste the error message. James On Jul 2, 2012, at 12

Hello, I am trying to analyze an RNA helix with curves+. I keep receiving an error message that base atom C1* is missing from the pdb. C1 atoms are certainly all there. Any advice on how to troubleshoot this will be much appreciated. Sincerely, Nikolai Suslov

Hi Alex Out of the possible issues I suggested earlier I suspect most strongly you have sizeof(long) != 4. But Ian is indeed right to promote the canonical answer. Avoid such mess by using the API ;-) -- David On 2 July 2012 15:48, Ian Tickle wrote: > Hi Alex > > Wouldn't you be better off u

Hi Alex Wouldn't you be better off using the API (http://www.ccp4.ac.uk/dist/html/C_library/cmaplib_8h.html): that way your program will have a good chance of still working in another 10 years' time! Cheers -- Ian On 2 July 2012 14:41, Soares, Alexei wrote: > Hello, Alex here. > > Ten years ag

Re: [ccp4bb] How do I read a CCP4 map header?

2012-07-02 Thread David Waterman
Hi Alex, The map header is binary, not text, which explains the junk you saw in your terminal. One thing to be careful of is where the map file came from. The map format doesn't specify the byte order written to disk, so your reading routine has to identify whether it was written by a little- or b

2012-07-02 Thread Soares, Alexei
Hello, Alex here. Ten years ago, I read CCP4 maps this way, but it no longer works ... can anyone tell me why? Note that map1 is an integer so that multiple headers can be read. Also, supposedly the map header is text, but a simple "head -1" dumps lots of digital garbage from the map header.

Hi James I would say that you are completely correct in your assessment of the situation. The Bilbao server clearly lists only the unique 'standard' settings, leaving to the user the task of rotating the basis to whatever is required by the unit cell convention, or other criteria such as isomorph
