I observe under some conditions that ctruncate sets some reflections
amplitudes to zero. AFAIU, this should not be happening as even
negative intensities (there are none in this particular dataset) should
produce FP>0 upon truncation.
66 out of ~23000 reflections are zeros after ctruncate is applied.
Nothing obvious comes up upon inspecting the corresponding hkl's, except
that one and only one is always zero (sg is P21212, so these are not
systematic absences). One curious thing is that the I/sigma for these
reflections is close to the average I/sigma in the highest resolution
range (but it varies and these reflections are in all resolution
ranges).
A bug?
