OpenMP in fftpack
by Keitaro Yamashita 31 Jan '19

31 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

Re: [cctbxbb] [git/cctbx] master: Fix typo geobox (1ad3fe055)
by Pavel Afonine 22 Dec '18

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.

Broken iotbx/pdb/cif test

According to Jenkins these two tests have been broken for several days - does anyone know what the issue is and could a fix be applied? Both look like the same error. iotbx/regression/tst_pdb_as_cif.py iotbx/regression/tst_data_manager.py These have been failing since this commit: https://github.com/cctbx/cctbx_project/commit/2c119fcf012ca4cc60dfce231902c… The tests also fail locally for me (not just on Jenkins).

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
by Pavel Afonine 14 Nov '18

Perhaps someone can reply Wen.. Pavel -------- Forwarded Message -------- Subject: Re: indexing diffraction pattern Date: Sat, 10 Nov 2018 09:30:53 -0500 From: Wen Jiang <jiang12(a)purdue.edu> To: Pavel Afonine <pafonine(a)lbl.gov> Pavel, Sorry for insufficient details. 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
by Luc Bourhis 09 Nov '18

09 Nov '18

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

construct hkl arrays from number of reflections and resolution
by Robert Oeffner 29 Oct '18

29 Oct '18

I would like a function that spits out an HKL array as a function of number of reflections, dmin and dmax. It's quite likely this has already been done somewhere in the CCTBX. Would anyone know if this is the case rather than me having to reinvent the wheel?

Bootstrap on macOS Mojave

Folks, For info: https://github.com/cctbx/cctbx_project/issues/240 wxPython appears to not build on macOS Mojave - possibly updated C++ standards or something who knows? But I guess because we are fixed on an old (4 years, just about [1]) version of wxPython this should not be a surprise. We should probably have some kind of answer for this though - thoughts?
