Hi Folks, Trying to write some code to return the average E^4 across (some) bins for an mtz file, I got to def main(): import sys from iotbx import reflection_file_reader for argv in sys.argv[1:]: reflection_file = reflection_file_reader.any_reflection_file( file_name = argv) if reflection_file.file_type() is None: continue miller_arrays = reflection_file.as_miller_arrays() for ma in miller_arrays: E4(ma) def E4(ma): f = ma.as_intensity_array() f = f.array(data=f.data()/f.epsilons().data().as_double()) f.set_observation_type_xray_intensity() f.setup_binner(auto_binning = True) sm = f.second_moment(use_binning = True) sm.show() if __name__ == '__main__': main() but I have no idea how to actually extract the information I want from sm as this only has show() which gives Graemes-MacBook-Pro:PlayPen graeme$ cctbx.python E4.py /Users/graeme/projects/sci-397/DEFAULT/scale/AUTOMATIC_DEFAULT_scaled.mtz unused: - 20.8668 [ 0/7 ] bin 1: 20.8668 - 5.8873 [221/235] 2.3863 bin 2: 5.8873 - 4.6904 [216/221] 1.9823 bin 3: 4.6904 - 4.1026 [221/222] 1.9925 <snip> bin 47: 1.6553 - 1.6435 [153/209] 2.2051 bin 48: 1.6435 - 1.6320 [143/198] 2.2021 bin 49: 1.6320 - 1.6208 [141/204] 2.7085 unused: 1.6208 - [ 0/0 ] unused: - 20.8668 [ 0/9 ] bin 1: 20.8668 - 7.1654 [201/225] 2.2405 bin 2: 7.1654 - 5.7261 [202/213] 1.9109 bin 3: 5.7261 - 5.0137 [216/223] 2.0162 bin 4: 5.0137 - 4.5605 [207/212] 2.0043 <snip> bin 87: 1.6456 - 1.6393 [126/192] 2.5521 bin 88: 1.6393 - 1.6330 [122/210] 2.0195 bin 89: 1.6330 - 1.6269 [131/224] 2.6251 bin 90: 1.6269 - 1.6208 [120/212] 3.0912 unused: 1.6208 - [ 0/0 ] Really I would like the value programatically or at least a way of getting back an array of the binned values so I can average them myself (which is obviously trivial) Any suggestions? Thanks, Graeme ps - most of this code is ripped from iotbx.reflection_statistics :o) -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
