Hi all, It seems that a flex.double array containing "nan" values doesn't survive pickling as in: oeffner@grove:~$ cctbx.python Python 2.7.15 (default, Sep 11 2018, 23:48:45) [GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2 Type "help", "copyright", "credits" or "license" for more information.
from cctbx.array_family import flex import pickle flex_nans = flex.double(3, float('nan')) list(flex_nans)
[nan, nan, nan]
list(pickle.loads( pickle.dumps(flex_nans))) [0.0, 0.0, 0.0]
If the flex double is cast into a python list then it does survive pickling as in:
list(pickle.loads( pickle.dumps(list( flex_nans ))))
[nan, nan, nan]
I would like to use nan values to indicate missing or invalid data values. Would anyone have a suggestion how to go about this?
