Hi Matt,<br>
<br>
If asked to generate new flags, phenix.refine will use 1 for test
and 0 for work. However, it uses a smart flags interpretation
machinery that can guess the right choice, if possible (for example,
if 1 and 0 are flipped, it will take 0 as test just going by the
fraction). If you have flags from 0 to 19 it will figure it is ccp4
format and use 0 as test by default. On top of that the user always
can tell what flags to use as test flag. Also, the log file will
always tell what was chosen as test and work flags.<br>
<br>
Bottom line is: for phenix.refine does not care what value is used
for free/work flag as long as phenix.refine can guess it
automatically or the user explicitly specifies it.<br>
<br>
Reflection file editor from Phenix GUI can transfer the flags.<br>
<br>
I suggest you just try to do what you want and let us know should
you encounter any problem.<br>

<div>Dear All,<br>
<br>
I am trying to refine my model against a higher resolution
dataset. My colleage's old-low resolution dataset was
processed in HKL/scalepack and the FreeR was assigned by
Phenix.reflection file editor, which I assume the test set was
marked as "1". Now I got a new-higher resolution dataset, and
plan to process it in XDS/Aimless. I want to transfer the
FreeR set from his old mtz and also use his low res model for
the new refinement. My question is, when I transfer the FreeR
set from his old mtz with flag value as "1" in Aimless, is the
flag value now "1" or "0" in the new mtz output by Aimless?
Can Aimless recognize the FreeR flag from the old mtz which
are marked as "1"? <br>
</div>
<div><br>
I also read an old post from Nat Echols in 2011: "For Phenix,
1 is test, 0 is work, but you could reverse this and it will
still figure out what to do automatically", so does it mean it
doesn't matter if the FreeR is "1" or "0" in the mtz from
Aimless, if I use phenix.refine for my new dataset, Phenix can
figure out which is the correct FreeR value?<br>
<br>

<div>It's a mix of CCP4 and Phenix question, so I have crossed
posted it in the CCP4bb as well.<br>
<br>

<div>Many thanks,<br>
