<br>
(Disclaimer: I usually use phaser in ccp4, and I don't have the
latest version. Not everything I say may be applicable.)<br>
<br>
If you're running phaser in the default mode, the packing test
looks at the best (fewest clashes) solution, then screens all
other solutions relative to that. If your best solution has no
clashes, then even solutions below your clash threshold (e.g. 20
clashes) may get filtered out. I find this behavior annoying, and
I explicitly tell phaser to accept all solutions below X number of
clashes. <br>
<br>
I'm not sure how to make Phaser do this in Phenix, but I see in
the "Phaser-MR" window that there is an "Other Settings" button;
in the window this pops up, you can try selecting "allow" for the
packing function then "20" for the cutoff. This should work...<br>
<br>
Hope that helps,<br>
Matt<br>

there is a solution. When I look at the log file there are a few
solutions in the translation function that have fewer than the
allowed clashes, but they are still not recognized as potential
solutions. Why is that. Is there another parameter that I should
be looking at?<br>
