Re: [ccp4bb] .raw file from SAINT to pointless

Dear Georg, When you start SADABS, the first question is whether you rquire 'expert mode'. This mode asks more questions to set additional parameters. If you select expert mode, the second question is the maximum number of reflections. 200 is merely the default value. I would be

Re: [ccp4bb] Question on Refmac5

2015-01-06 Thread Tim Gruene
Dear Dialing, unless this has changed recently, in my experience refmac5 writes the PDB and MTZ file only at the end of refinement, not intermediately. Have you ruled out this is an issue with your operating system or file system setup? Maybe the timestamp is messed up e.g. through an NFS

Dear Georg, the option [y] in xprep from where you also get the data statistics prints the CC of your data set and also of two data sets if available. You can write it to a postscript file - in case you want the numbers for any reason you can read the postscript file as it is only a text file.

Re: [ccp4bb] Question on Refmac5

2015-01-06 Thread Laurent Maveyraud
Dear Dialing, have you any specific reasons to believe that the crated PDB file does not correspond to the refined model ? This could be easily checked by comparing the statistics written in the header of the PDB file and those at the end of the refmac logfile. If they do not differ, then

On the face of it, I wouldn’t get overly excited by the drop. However, I’ve been underwhelmed and wrong before. If you’ve got access to a synchrotron beamline that can shoot the material in-situ it might be a good experiment to try. Best of luck, Dave Dr. David Hargreaves Associate Principal

Re: [ccp4bb] Some advices on model modification

2015-01-06 Thread Roger Rowlett
How you approach this will depend substantially on the sequence identity between your target and your potential MR models. Definitely remove all non-protein atoms from your search model, as these are not likely at all to be present, or present at these positions, in your target. In addition to

2015-01-06 Thread vellieux
Hello, Keeping the waters in a model used for molecular replacement search is not a very good idea. I'd suggest first that you use a program like Chainsaw and possibly additional programs to fine-tune your search model to the problem that you are trying to solve. Also, reading material

Hi all, I have a heterogeneous collection of mtz files I'm trying to whip into some kind of standardized vocabulary shape, namely setting column names and types so that subsequent scripts can sensibly make maps and so forth. I have set up the ever-useful sftools to do most of this, but of course
