Re: [ccp4bb] DNase inhibitors

I have small crystals of protein DNA complex. I am worried about the possibility of presence of some DNases in the drop (I use DNase in the lysis buffer). I have Tris and MgCl2 in the crystallization condition, which makes me hesitant to use DEPC or EDTA/EGTA respectively. Are there any other D

Hi, I suggest you check which version of MOLREP you used. Currently, BALBES now actually use MOLREP in 'auto' mode for PST. The two should be the same. The difference may be because BALBES uses the latest version of MOLREP. Fei On 7/30/07, Eleanor Dodson <[EMAIL PROTECTED]> wrote: > I think th

[ccp4bb] problem in running DM (NCS averaging)

2007-07-30 Thread JOE CRYSTAL
Dear all, I tried to run DM for NCS averaging (DM module in CCP4i 6.0.2 installed under Windows XP), but the running failed at different stages with various error message as listed below. I was told it could be an installation problem, but I don't know how to fix it. I am wondering if you have

I think the error is in BALBES - there is a peak I guess at 0.95 0 0.01 but it must be too close to the origin to be a translation vector from one molecule to another. There are reasons for such peaks - sometimes spurious large terms in the data.. but they dont usually represent true molecula

Dear colleagues, For a particular MR problem I am dealing with, 'analyse_mr' suggests that there maybe a pseudo-translation vector as evidenced by the very significant non-origin peaks in the native patterson: e.g GRID 80 112 80 CELL 104.8290 151.2840 109.4910 90. 118.1310 90. A

Re: [ccp4bb] Problem converting CNS cv file to mtz using f2mtz

2007-07-30 Thread Eleanor Dodson
CNS format changes with the time of day and unfortunately f2mtz requires that you give a correct fortran format stt. This command script works from the GUI: Note that 1) you must the "skip lines" 2) you need X entries to skip unwanted characters . These include INDE (7x) FOBS= (6x) and also
