Hi All:

I am trying POINTLESS for detecting real space group using data processed
by HKL2000.  Apparently, POINTLESS cries for unmerged data.  I understand
using Mosflm might be the best in this case, but I am not familiar with
the program.

So I did the following to rescue but not sure if it is the right thing. 
1) Integrate (denzo) as P1 space group in HKL2000.  2) Scalepack in P1
with keyword "no merge".  3) Using COMBAT in CCP4 to covert to mtz and
specify the input .sca file as "Scalepack file nomerged (no partials)".

What I am more curious about, is what exactly does "unmerged" mean?  Does
it mean not reduced to asymmetric unit?  Or something happened much
earlier in data processing, like the "no partials" comment in COMBAT seems
to suggest?  If it is the latter case, why is it so important for symmetry
analysis in POINTLESS?

Regards,

Weikai
