Importing PyQt4 in litbx.python
by Gianluca SANTONI 08 Dec '17

08 Dec '17

Dear all, I'm having some troubles recently in importing pyqt4 in libtbx.python under Debian8. It used to work with a previous build compiled from the sources, but I don't find a reasonable way to make it work from the bootstrap installation. More details: 1) If I do in libtbx.python sys.path.append('/usr/lib/python2.7/dist-packages/') and "from PyQt4 import QtCore", I get an unidentified symbol: PyUnicodeUCS4_AsLatin1String 2) If I try to compile cctbx as I did in the past "python ../libtbx/configure.py cctbx" no make file is produced. Maybe I'm missing something Thanks everybody for your help. Gian -- Gianluca Santoni, PhD ESRF structural biology group 71 avenue des Martyrs 38027 Grenoble cedex (France)

rotate_translate_map function causes "splinching"
by Pearce, N.M. (Nick) 29 Nov '17

29 Nov '17

Hi all, I’m having a problem with the rotate_translate_map function from cctbx.maptbx. I have a 3D array (a mask of 0s and 1s, in this case) that I’m writing as a CCP4 map file. If I write it out “on the origin” (without running rotate_translate_map), then it’s fine (see attached “before.png”). However, if I apply the rotate_translate_map function and then write it out, odd features appear at the edge of the unit cell (see “after.png”). It is NOT the case that the map is going through the “periodic boundary conditions” of the unit cell (the shift is less than one unit cell, as shown by the structure which is transformed by the same amount). The minimal code is: ——————————— array = cctbx.maptbx.rotate_translate_map( unit_cell=self.unit_cell(), map_data=array, rotation_matrix=scitbx.matrix.rec([1,0,0,0,1,0,0,0,1], (3,3)).elems, translation_vector=(-1.0*scitbx.matrix.rec((X,Y,Z), (3,1))).elems ) # Write the map iotbx.ccp4_map.write_ccp4_map( file_name=f_name, unit_cell=self.unit_cell(), space_group=self.space_group(), map_data=array, labels=flex.std_string(['’]) ) ——————————— where (X,Y,Z) is a tuple for the origin shift. Is there something stupid that I’m missing? Has anyone else had the same problem? The only code for a rotate_translate_map function I could find was actually in maptbx/average_densities.h and I couldn’t see anything obviously “wrong”… though I’m not that familiar with C++. The maps and files can be found at https://www.dropbox.com/sh/xqrsk5lcn603416/AABiVO74g6A_jZMGn_DjxOmka?dl=0 all “grid” files are without translation, and all “ref” files are after translation. both are written out exactly the same (the iotbx.ccp4_map call above). I’m using the cctbx bundled with a ccp4 nightly from 2016-10-22. Thanks, Nick [cid:[email protected]][cid:[email protected]]

cctbx versions causing indentation crash?
by Magnus Andersson 10 Nov '17

10 Nov '17

Hi all, I have a script that runs fine on my old computer, but crashes on my new computer with the error message: IndentationError: unexpected indent This script is (amongst other things) calling the softwatre Coot such as: subprocess.call(["""coot --no-graphics<<end/n (handle-read-draw-molecule-with-recentre \""""+str(inf)+"""\" 1) (set-refinement-immediate-replacement 1) (set-refine-max-residues 40) (regularize-zone 0 \" \" """+str(res1-2)+""" """+str(res3)+"""\" \") (accept-regularizement) (regularize-zone 0 \" \" """+str(res3)+""" """+str(res2+2)+"""\" \") (accept-regularizement) (write-pdb-file 0 \""""+str(outf)+"""\") (coot-real-exit 0)"""], shell=True) which is ok on my old system. I am trying to find the most likely source of this error. Here are the differences: - OLD cctbx = uses Python 2.7.10, NEW cctbx 2.7.14 - OLD OSX = 10.10.5 (i.e. Yosemite), NEW OSX = 10.11.5 (i.e. El Capitan) - OLD Coot = vers 0.8, NEW Coot = vers 0.8.8 [old Coot install was from Fink but this shouldn’t matter I think] Perhaps someone has encountered something similar or has an educated guess on whether different cctbx versions can cause such errors?

Hello, I am not normally using cctbx but I’m trying to run a script that imports modules as follows: import sys,io,os import subprocess import numpy import pickle import math import pylab #import pymol import time import scipy import iotbx.pdb import cctbx import mmtbx.model from scipy.optimize import fmin, fmin_cg, leastsq from scipy.interpolate import interp1d import datetime from numpy.random import random_sample from cctbx.array_family import flex from scitbx.math import superpose I have installed cctbx and run with cctbx.python. How can I import scipy into the cctbx python?

Re: [cctbxbb] [git/cctbx] master: libtbx.clean_clutter runs isort in supported locations (612869130)
by Aaron Brewster 26 Oct '17

26 Oct '17

Hi Markus, could isort be added as a dependency instead? If I understand this commit right, when running libtbx.clean_clutter, if .isort.cfg is present and isort is not installed, pip is invoked to install isort. l'm nervous about pip being imported anywhere in our code, especially to install things when running code unrelated to installation. It's important to keep installation of stuff separate from running of stuff. Otherwise, it's impossible to keep dependencies straight. -Aaron On Thu, Oct 26, 2017 at 2:29 AM, CCTBX Commit via DLS Jenkins < graeme.winter(a)gmail.com> wrote: > Repository : ssh://g18-sc-serv-04.diamond.ac.uk/cctbx > On branch : master > > ------------------------------ > > > commit 612869130a6210d49a573a3cff04416a9de67808 > Author: Markus Gerstel <markus.gerstel(a)diamond.ac.uk> > Date: Thu Oct 26 10:29:05 2017 +0100 > > libtbx.clean_clutter runs isort in supported locations > > > ------------------------------ > > > 612869130a6210d49a573a3cff04416a9de67808 > libtbx/command_line/clean_clutter.py | 26 ++++++++++++++++++++++++++ > 1 file changed, 26 insertions(+) > > diff --git a/libtbx/command_line/clean_clutter.py > b/libtbx/command_line/clean_clutter.py > index d49bf4c25..8fc2e53c8 100644 > --- a/libtbx/command_line/clean_clutter.py > +++ b/libtbx/command_line/clean_clutter.py > @@ -32,6 +32,24 @@ def clean_clutter_in(files, tabsize=8): > os.remove(tmpname) > raise > > +def isort(path): > + try: > + import mock > + from isort.main import main > + except ImportError: > + # Install package if necessary > + import pip > + pip.main(['install', 'isort', 'mock']) > + import mock > + from isort.main import main > + with mock.patch.object(sys, 'argv', ['isort', '-y', '-ac', '-vb']): > + oldcwd = os.getcwd() > + try: > + os.chdir(path) > + main() > + finally: > + os.chdir(oldcwd) > + > def run(): > opt_parser = (option_parser( > usage=""" > @@ -60,6 +78,7 @@ by running svn commit.""") > if co.committing and files: > opt_parser.show_help() > exit(1) > + run_isort_in_path = False > if co.committing: > try: > files = list(subversion.marked_for_commit()) > @@ -72,7 +91,14 @@ by running svn commit.""") > else: dir = files[0] > files = [ c.path for c in libtbx.file_clutter.gather([dir]) > if c.is_cluttered(flag_x=False) ] > + if os.path.exists(os.path.join(dir, '.isort.cfg')): > + run_isort_in_path = dir > clean_clutter_in(files, tabsize=co.tabsize) > + if run_isort_in_path: > + try: > + isort(run_isort_in_path) > + except Exception as e: > + print("Did not run isort (%s)" % str(e)) > > if (__name__ == "__main__"): > import sys >

That's 3 weeks from now.

Folks, phenix_regression/allsvn assumes if you are using git that you are using git/svn These days probably not true ;o) Viz: cd cctbx_project; git svn rebase Unable to determine upstream SVN information from working tree history ccp4io: At revision 160. ccp4io_adaptbx: At revision 142. cd dials; git svn rebase Unable to determine upstream SVN information from working tree history someone on phenix-land want to have a look at this? Obviously not a blocker but is untidy!
