There are two known issues with ctruncate: one with the anisotropic
correction and one with the fitting of <F^2> as a function of resolution.
The first is easily addressed - try turning off the anisotropy
correction. That may solve the problem.

Dear all,
For the same input in a ccp4i (v .2.0.4) Scala (v. 3.3.9) job I have
obtained the following:
with CTRUNCATE (v. 1.0.01)
==================
Col Sort Min Max Num % Mean Mean Resolution
Type Column
num order Missing complete abs. Low
High label
5 BOTH ? ? 12586 0.00 ? ? -999.00 0.00 F
F_BA2
with TRUNCATE (v. 6.1)
==================
5 NONE 1.8 152.8 766 93.91 20.26 20.26 24.93 2.80 F
F_BA2
The final file after Ctruncate cannot be read in by some programs
although mtzdump can dump it.
Thanks for any comments on possible reasons for this problem.
Ricardo
