Hi all,
We recently installed arp/warp 7.0.1 under ccp4i (CCP4_6.0.2).
The installation went fine. We just wanted to add water molecules to
the current model. We toggle to "use" in the box
"For refmac5 refinement do -use- the Free R flag"
Also, we choose the due flag in the box
Determine the free R label for reflections to be escluded from
refinement -FreeR_flag-"
When we ask the program to run, it does, but without using the
Free R-flag; it says "FreeR will not be used" in the log file and the
R-free is reported as 0.000. Curiously, the box where the free R label
is becomes blank.
We googled and searched archive lists (both warp and CCP4).
What the problem might be ?
Jorge
