phenix version 1.4-3: problem with bulk solvent scaling
Hi, I am currently refining a good 1.6 Angstroem data set using Phenix. Thereby I noticed a significant difference of R-free (>3%) depending on whether I used phenix version 1.3-rc6 (installed on my Mac laptop) or phenix version 1.4-3 (installed on my linux work station). Rfree differs by more than 3% (!) although I am using the same starting model, the same reflection file and the same refinement protocol (shown at the end of this email with detailed R and R-free factors for the 3 steps). In my opinion, my phenix 1.4-3 installation has a problem in the "bulk solvent modeling and scaling" steps. Indeed, I find in the log file that the "overall anisotropic scale matrix" shows all values set to zero. Analogous the "maximum likelihood estimate for coordinate error". This is true in all steps where an "overall anisotropic scale matrix" is calculated. Here is one example during 1.4-3 refinement: ====================== bulk solvent modeling and scaling ====================== |--(resolution: 1.61 - 29.59 A; n_refl. = 99535)------------------------------| | | | r_work= 0.3419 r_free= 0.3358 ksol= 0.39 Bsol= 19.12 scale= 1.247 | | | | overall anisotropic scale matrix (Cartesian basis; B11,B22,B33,B12,B13,B23):| | (0.00,0.00,0.00,0.00,0.00,0.00); trace/3= 0.00 | | | | maximum likelihood estimate for coordinate error: -0.00 A | | x-ray target function (ml) for work reflections: 5.981207 | |-----------------------------------------------------------------------------| The same example during 1.3-rc6 refinement: ===================== bulk solvent correction and scaling ===================== |-macro cycle = 1-(resolution: 1.61 - 29.59 A; n_refl. = 99537)---------------| | | | r_work= 0.3153 r_free= 0.3064 ksol= 0.40 Bsol= 43.79 scale= 1.087 | | | | overall anisotropic scale matrix (Cartesian basis; B11,B22,B33,B12,B13,B23):| | (-4.01,-5.36,-8.20,-0.00,2.74,0.00); trace/3= -5.86 | | | | maximum likelihood estimate for coordinate error: 0.33 A | | x-ray target function (ml) for work reflections: 5.946583 | |-----------------------------------------------------------------------------| I am asking now: Did something go wrong during my Phenix installation?

I am using 10.4.11 on OS X . However, at the moment I am more interested in getting phenix to run correctly on my linux box: Fedora core 9, kernel 2.6.25.11-97.fc9.i686. Thanks, Oliv Paul Adams wrote:

Hi Oliv, I have a guess about what is wrong, but before I say it, could you please send us the exact command you are using. IF you are specifying a .def or .eff file in the command line, could you please send this .eff or .def files as well. Pavel. On 1/30/2009 4:02 PM, Oliv Eidam wrote:

Hi Oliv, I now see the problem... It is a bug in phenix.refine that we fixed sometime ago and the next PHENIX release will have it. If you go into your .def file and replace "minimization_b_cart = False" with "minimization_b_cart = True" that will fix the problem. If you see something like this in future, always make sure that "minimization_b_cart = True" in your input parameter file. Please let me know if this helped or if you have any other problems. Pavel.

Rfree differs by more than 3% (!) although I am using the same starting model, the same reflection file and the same refinement protocol (shown at the end of this email with detailed R and R-free factors for the 3 steps). In my opinion, my phenix 1.4-3 installation has a problem in the "bulk solvent modeling and scaling" steps. Indeed, I find in the log file that the "overall anisotropic scale matrix" shows all values set to zero. Analogous the "maximum likelihood estimate for coordinate error". This is true in all steps where an "overall anisotropic scale matrix" is calculated. Here is one example during 1.4-3 refinement:
====================== bulk solvent modeling and scaling ======================
|--(resolution: 1.61 - 29.59 A; n_refl. = 99535)------------------------------| | | | r_work= 0.3419 r_free= 0.3358 ksol= 0.39 Bsol= 19.12 scale= 1.247 | | | | overall anisotropic scale matrix (Cartesian basis; B11,B22,B33,B12,B13,B23):| | (0.00,0.00,0.00,0.00,0.00,0.00); trace/3= 0.00 | | | | maximum likelihood estimate for coordinate error: -0.00 A | | x-ray target function (ml) for work reflections: 5.981207 | |-----------------------------------------------------------------------------|
The same example during 1.3-rc6 refinement:
===================== bulk solvent correction and scaling =====================
|-macro cycle = 1-(resolution: 1.61 - 29.59 A; n_refl. = 99537)---------------| | | | r_work= 0.3153 r_free= 0.3064 ksol= 0.40 Bsol= 43.79 scale= 1.087 | | | | overall anisotropic scale matrix (Cartesian basis; B11,B22,B33,B12,B13,B23):| | (-4.01,-5.36,-8.20,-0.00,2.74,0.00); trace/3= -5.86 | | | | maximum likelihood estimate for coordinate error: 0.33 A | | x-ray target function (ml) for work reflections: 5.946583 | |-----------------------------------------------------------------------------|
I am asking now: Did something go wrong during my Phenix installation? I already re-installed Phenix (no errors): same result. Do I have to change something in my input files? I should probably mention that "bulk_solvent_and_scale = True" in my input .def files.
Any help appreciated. Many thanks,
Oliv
