Not sure about the selection problem but the missing commands are likely molprobity.reduce and molprobity.probe. Chris, you should be able to change that. Cheers Nigel --- Nigel W.

Molprobity / CCTBX incompatibility
by Robert Nolte 11 Aug '19

11 Aug '19

We are trying to reinstall our internal molprobity server, and have hit an issue with the github version where it appears to be a version conflict with the version of cctbx that is currently being downloaded by configuration script in the master branch of molprobity. We are getting errors when we run the validation routine such as Unrecogized PHIL parameter: data_version=8000 or Unrecognized PHIL parameter: clash_cutoff=-0.4 The analysis for clashscore, rotalyze, are failing to run and we get a number of divide by zero errors for several of the other 'visualize' and 'eff_resolution' routines. Can you help get this working. Thanks, Bob Nolte GSK monitors email communications sent to and from GSK in order to protect GSK, our employees, customers, suppliers and business partners, from cyber threats and loss of GSK Information.

Failing tests on python3 builds
by richard.gildea＠diamond.ac.uk 30 Jul '19

30 Jul '19

Hi, Whilst looking into test failures reported against a pull request I currently have open, I noticed that there are several (9) failing tests on the Python 3 build. It appears that Markus reported these 3 weeks ago - is anyone looking into these failures? Having builds permanently reporting failure isn't particularly helpful as it discourages people from looking at the results, and will likely lead to further Python 3 regressions being introduced into the codebase. https://dev.azure.com/cctbx/cctbx_project/_build/results?buildId=240 https://github.com/cctbx/cctbx_project/issues Cheers, Richard Dr Richard Gildea Data Analysis Scientist Tel: +441235 77 8078 Diamond Light Source Ltd.

"duplicate" cif categories
by wtempel 06 Jul '19

06 Jul '19

Hi, wwpdb onedep recently rejected a file that I had manipulated (but not validated, I admit) in IOTBX. The error was "duplicate categories", or a similar complaint. I had added _reflns.* items related to data processing to a phenix.refine cif file that already included a _reflns.B_iso_Wilson_estimate. Merely running sort() on the relevant block made the error go away, but who knows what side effects there may have been. Does the CCTBX ecosystem provide some higher-level management of cif categories? Thanks. Wolfram

Fwd: Conda/DIALS 1.14.5 source build with --use-conda does not work
by Nicholas Devenish 27 May '19

27 May '19

(Forwarding this manually as apparently my Diamond address isn't on cctbxbb) Hi All, On 24 May 2019, at 14:12, David Waterman - UKRI STFC < david.waterman(a)stfc.ac.uk<mailto:[email protected]>> wrote: > In the process, I discovered that the source builds we point to from > https://dials.github.io/installation.html don't work with --use-conda > because the paths to various packages are out of date. This seems to be to be a fundamental problem with the conda implementation? Let’s try to reproduce an old build from, say, 1st march: the point in cctbx_project at which dials 1.14 split off. This is https://github.com/cctbx/cctbx_project/commit/35652e06564da7ff989500a6d929b… . Try reproducing this point: git clone git(a)github.com<mailto:[email protected]>:cctbx/cctbx_project.git modules/cctbx_project ( cd modules/cctbx_project/ && git checkout 35652e06564da7ff989500a6d929bc595f69040f ) ln -s modules/cctbx_project/libtbx/auto_build/bootstrap.py . ./bootstrap.py base --use-conda —> many "An HTTP error occurred when trying to retrieve this URL.” This means that with the current conda implementation it’s impossible to guarantee reproducibility for any build beyond the past few days, without lots and lots of manual work reconstructing the versioning out of the file list dump. Because the version constraints aren’t kept with the repository, this means that a source distribution is not nearly enough to recreate any given release. This seems like a problem? Nick

Python3 / scons / non-conda builds
by Graeme.Winter＠Diamond.ac.uk 12 May '19

12 May '19

Dear All, Back in the mists of time, one could build cctbx modules without bootstrap or conda by having the right modules available yourself - a so-called baseless install which I think is still important in X-fel land? Anyhow, trying this with Python3 suggests that we have some special constraints which are perhaps too tight regarding module locations - for example scons - Grey-Area p3_compile :( $ pip3 install scons Collecting scons Downloading https://files.pythonhosted.org/packages/65/41/ac58638421414acc64e26fc120c81… (831kB) 100% |████████████████████████████████| 839kB 14.3MB/s Installing collected packages: scons Successfully installed scons-3.0.5 You are using pip version 19.0.1, however version 19.1.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. Grey-Area p3_compile :) $ make ./bin/libtbx.scons -j "`./bin/libtbx.show_number_of_processors`" ModuleNotFoundError: No module named 'SCons' During handling of the above exception, another exception occurred: Sorry: SCons is not available. A possible solution is to unpack a SCons distribution in one of these directories: "/Users/graeme/svn/scr" "/Users/graeme/svn/scr/cctbx_project" SCons distributions are available at this location: http://www.scons.org/ It may be necessary to rename the unpacked distribution, e.g.: mv scons-0.96.1 scons make: *** [default] Error 1 Grey-Area p3_compile :( $ which scons /Library/Frameworks/Python.framework/Versions/3.7/bin/scons Should we require that scons is installed as part of cctbx when it is already installed on the system? If we *do* have to have this constraint, maybe that should be checked at configure time (where it complains about six and future) Thoughts? In other news - the syntax changing branch referenced in https://github.com/cctbx/cctbx_project/pull/325 now compiles correctly on Python3 (note: not run, just compile but this means that it’s purpose is done) for the modules which it intends to touch and has no conflicts right now… Best wishes Graeme -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.

Overloading Python builtin names with local variables
by Graeme.Winter＠Diamond.ac.uk 03 May '19

Morning all, As a side-effect of looking at some of the Python3 refactoring I stumbled across a few places where e.g. range is used as a variable name. While this is fine and legal, when moving the code to Python3 xrange => range and from builtins import range is a back-port of Python3 range to Python2 which allows the existing behaviour of xrange generator to be maintained This is fine except for where range is a variable name and we then get a “variable referenced before assignment” type error As a general statement I would say overloading Python reserved names with local variables is untidy at best, and can easily cause confusion (as well as real problems as identified above) - I have therefore taken the liberty of adding a tool to libtbx which can be used to find such variables to give people a chance to avoid them: Grey-Area dxtbx :) [master] $ libtbx.find_reserved_names format/ Checking format/ format/FormatSMVRigakuSaturn.py:239 "format" format = self._scan_factory.format("SMV") format/FormatTIFFRayonixESRF.py:36 "format" format = {LITTLE_ENDIAN: "<", BIG_ENDIAN: ">"}[order] format/FormatTIFFRayonixESRF.py:29 "bytes" width, height, depth, order, bytes = FormatTIFFRayonix.get_tiff_header( format/FormatCBFMini.py:231 "format" format = self._scan_factory.format("CBF") format/FormatTIFFRayonix.py:176 "format" format = self._scan_factory.format("TIFF") format/FormatTIFFRayonix.py:31 "bytes" width, height, depth, order, bytes = FormatTIFF.get_tiff_header(image_file) format/FormatTIFFRayonix.py:74 "bytes" width, height, depth, order, bytes = FormatTIFF.get_tiff_header(image_file) format/FormatSMVRigakuEiger.py:243 "format" format = self._scan_factory.format("SMV") format/FormatSMVADSC.py:212 "format" format = self._scan_factory.format("SMV") format/Registry.py:88 "format" for format in sorted(self._formats, key=lambda x: x.__name__): format/FormatSMVJHSim.py:141 "format" format = self._scan_factory.format("SMV") format/FormatSMVRigakuPilatus.py:188 "format" format = self._scan_factory.format("SMV") format/FormatSMVADSCSN928.py:47 "format" format = self._scan_factory.format("SMV") format/FormatRAXISIVSpring8.py:134 "format" format = self._scan_factory.format("RAXIS") format/FormatTIFFRayonixSPring8.py:31 "bytes" width, height, depth, order, bytes = FormatTIFFRayonix.get_tiff_header( format/FormatSMVADSCmlfsom.py:37 "format" format = self._scan_factory.format("SMV") format/FormatTIFFBruker.py:174 "format" format = self._scan_factory.format("TIFF") format/FormatTIFFBruker.py:31 "bytes" width, height, depth, order, bytes = FormatTIFF.get_tiff_header(image_file) format/FormatTIFFBruker.py:71 "bytes" width, height, depth, order, bytes = FormatTIFF.get_tiff_header(image_file) format/FormatCBFMiniADSCHF4M.py:26 "format" for format in ["%a_%b_%d_%H:%M:%S_%Y"]: format/FormatCBFMiniADSCHF4M.py:169 "format" format = self._scan_factory.format("CBF") format/FormatSMVADSCNoDateStamp.py:54 "format" format = self._scan_factory.format("SMV") format/FormatSMVRigakuSaturnNoTS.py:228 "format" format = self._scan_factory.format("SMV") format/FormatPYunspecified.py:152 "format" format = "" format/FormatSMVRigakuA200.py:234 "format" format = self._scan_factory.format("SMV") format/FormatCBFMiniEigerPhotonFactory.py:131 "format" format = self._scan_factory.format("CBF") format/FormatSMVTimePix_SU.py:97 "format" format = self._scan_factory.format("SMV") format/FormatCBFMiniPilatus.py:83 "format" format = self._scan_factory.format("CBF") format/FormatCBFMiniPilatusHelpers.py:22 "format" for format in ["%Y-%b-%dT%H:%M:%S", "%Y-%m-%dT%H:%M:%S", "%Y/%b/%d %H:%M:%S"]: format/FormatSMVADSCSNAPSID19.py:91 "format" format = self._scan_factory.format("SMV") format/FormatCBFMiniEiger.py:216 "format" format = self._scan_factory.format("CBF") format/FormatSMVNOIR.py:218 "format" format = self._scan_factory.format("SMV") format/FormatSMVCMOS1.py:197 "format" format = self._scan_factory.format("SMV") format/FormatRAXIS.py:238 "format" format = self._scan_factory.format("RAXIS") is an example where “format” is scattered all over the place but is also a useful function - replacing with fmt will mean the same and avoid this overloading, as an example. This uses AST parsing to work through the code and find variable assignments - doing this for dials found lots of examples of “file” and “type” being used. How much people care about this is a local issue, but I thought the tool would be useful All the best Graeme -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.

modulo operation on flex.double
by Robert Oeffner 11 Apr '19

11 Apr '19

Hi, I have a flex.double array of phase values between -360 and 360 degrees I would like to cast them all in one go to lie within 0 to 360. Does anybody know if there is a nice way of doing this with flex arrays? The modulo operator doesn't seem to be supported for flex arrays unlike the +, -, * and the / operators. This would otherwise be handy as I could then convert the array in one line of code like phases = phases % 360.0 If not I guess I'll have to numpy the problem :-) Many thanks, Rob

Hi all, how does one configure, and run inside a jupyter notebook, a cctbx-enabled kernel, beginning with a downloaded [cctbx build]( http://cci.lbl.gov/cctbx_build/)?

mtz2map gridding
by Elliot Nelson 21 Feb '19

21 Feb '19

Hi All, I've been trying to use Phenix.mtz2map to sample maps to a particular array size with the "gridding" option, but found that this seems to have no effect on the output of the program. I was wondering whether there were some restrictions to the integers that are permitted or otherwise what might be the cause of this behaviour. Having hunted through the code it seems to just set n_real in the crystal gridding, which is then fed into an fft - possibly the latter ignores n_reals that aren't sensible? Any idea?

OpenMP in fftpack
by Keitaro Yamashita 30 Jan '19

30 Jan '19

Dear CCTBX/PHENIX developers, According to PHENIX FAQ: https://www.phenix-online.org/documentation/faqs/index.html#general > In addition to these options, it is also possible to compile phenix.refine and Phaser with the OpenMP library, which automatically parallelizes specific instructions such as the FFT. This requires using the source installer for Phenix, and adding the argument "--openmp" to the install command. Because of threading conflicts, OpenMP is not compatible with the Phenix GUI. FFT in phenix.refine can be parallelized if OpenMP is enabled. However, it seems incorrect since 2017 due to this change: https://github.com/cctbx/cctbx_project/commit/3e932248e0491847a04ddeee429f8… The FAQ may need updating, but I am curious to know why it is disabled now. Best regards, Keitaro

Bad idea to hard-wire package name into lowest level code. Now imagine we need the same for afit, amber, quantumbio, rosetta, etc.. Are we going to have a page-long block of "if" statements. Please re-think and remove. For example, whether you want to shift it or not can be a parameter that you cast way level up in the context specific code.

forcing building boost_python early in SConscript
by Robert Oeffner 17 Nov '18

17 Nov '18

We are working on a newer version of Phaser. The new SConscript file for Phaser imports features from boost_python. Therefore it is currently not straightforward to build it since an empty build directory does not yet contain the boost_python module to be imported by SConscript (or python). So SCons crashes when it reads the new Phaser SCsonscript stating that boost_python cannot be imported. Currently our workaround is to first build CCTBX alone and then subsequently to build Phaser. My question is if it is possible to specify dependencies in cctbx_project/boost_adaptbx/SConscript to force building boost_python early on. On Windows boost_thread and a few other libraries are built before other SConscript files are read. So I have put some Depends(boost_thread, boost_python) andDepends(boost_thread, boost_python_meta_ext) statements into cctbx_project/boost_adaptbx/SConscript. These do seem to force building the boost_python.lib and .dll files. But building the boost_python_meta_ext python module fails with the error: boost_adaptbx\meta_ext.cpp(14): fatal error C1083: Cannot open include file: 'boost_adaptbx/type_id_eq.h' It's possible that I'm not using SCons as it's supposed to be used. Let me know if anyone has a suggestion on how to force building boost_python before other SConscript are read.

Fwd: Re: indexing diffraction pattern

Perhaps someone can reply Wen..

The scenario is that I have a numpy 2D array of float values that represents an image of "diffraction pattern" (generated by an image processing operation, not actual X-ray diffraction). I need to determine the peak positions and then find a 2D lattice (two 2D vectors) going through these peaks. I have my own simple functions that can detect the peaks and find a 2-D lattice to cross the peaks but it often fails when the "diffraction pattern" is not very clean. Thus, I want to find a more robust method that works well when the peaks are relatively weak, not very sharp, and when there are some spurious peaks off the lattice. I think these tasks are exactly what cctbx has solved for indexing X-ray diffraction images. Hope that these explanations help clarify the problem.

Windows woes

Hi, Trying to install cctbx on Windows 10, 1. install latest python 2 from Python.org 2. python2 bootstrap.py —builder=cctbxlite —with-python=\path-to-python-from-step-1 It fails because of missing module “builtins”. So I installed pip, then used it to install “future”. Then I had to install “six” with pip. Am I being stupid or cctbx does not install out of the box anymore? Best wishes, Luc J Bourhis

Python 3 and CCP4
by David Waterman 02 Nov '18

02 Nov '18

Hi folks, It's great to see the momentum building behind the project to migrate to Python 3. From the roadmap <https://github.com/cctbx/cctbx_project/wiki/Python-3-roadmap>, there is clearly still some way to go, but current activity makes me wonder if the proposed deadline of complete migration by 2020 might be beaten easily. What is not clear from the roadmap is whether there are any plans for a post-transition grace period, in which we have switched from writing forwards compatible Python 2 code to writing backwards compatible Python 3 code. Has this been thought about? Or will it be the case that the first commit of Py3-only code seals the deal? I ask because CCP4 has to support a large number of Python projects and these have not all considered the Python 3 switch nearly as seriously as cctbx yet. What I would like to request is a reasonable period of backwards compatibility is ensured to allow other CCP4 projects to catch up, and that this protected period is enshrined within the roadmap or developer guidelines. What do you think? Best wishes -- David
