Does it matter? The refinement will only use observed reflections.
As Andrew says your output from dataprocessing includes a complete list of all possible indices to the upper resolution limit with a Free R flag assigned to the indices. This makes it easier to keep the same FreeR assignments for all your sets of measurements, which is a good thing.. 

There is a library call which REFMAC could use which would return the actual limits of the observed data - that small modification to the program would give a more sensible log file for the refinement. 

At present the REFMAC outputs a reflection list will include all indices,  with the Fcalc PHIcalc information listed for missing data . I find that quite useful in some cases, but if you do not wish to use the terms there are ways of excluding them from subsequent calculations..

Dear All,

As far as I know it could happen when you are using i2. We are working to fix this problem. At the moment the best solution is to use advanced options in the refmac interface and define resolution limits explicitly. For example you can add in the advanced options:


resolution 37 2.5

where these resolution limits are from the aimless output. Low resolution limit should not affect refinement behaviour, however it may cause problem during deposition.

We will have better solution soon. I2 has many good features. Please report if you see some misbehaviours.

Best wishes,
Garib

P.S. you can also use advanced options to do things that are not available on the interface yet.
1) refinement against electron diffraction. Add

source EC MB   #  electron form factor will be used using Mott-Bethe formula

2) you can add occupancy refinement

etc

Dear All,

I am noticing that the low resolution in the reflections files after scaling with aimless and after refinement with refmac does not coincide.
In a case I have 37A with aimless but for some reason refmac is 67A.

Any idea?
All the best,
R.
