I thought it would be good to follow up with the solution to this problem,
in case someone else has been suffering with it in silence.
It turns out that, at some point, the Windows version of CCP4 release
6.1.13 included a newer version of Phaser (2.2.1), but the ccp4i interface
for that release is designed for Phaser version 2.1.4. Because there were
some small syntax changes between those versions, some jobs will fail,
particularly those for SAD phasing. The easiest fix is to replace the
Phaser executable with the 2.1.4 version, which you can obtain by
contacting us. So if anyone else has been having issues with this, please
let us know!
In the not too distant future, version 6.2 of CCP4 should come out, and
that will contain Phaser version 2.3 as well as compatible ccp4i GUIs.

After updating CCP4 includin Phaser_EP I can not run it - it can not read
my SIGFs - what is wrong? The error message is " SYNTAX ERROR: Use
SIGFPOS SIGF(+) or SIG+ " but my mtz-labels are LABIN F+ = F_Fe1(+) SIGF+
= SIGF_Fe1(+) F- = F_Fe1(-) SIGF- = SIGF_Fe1(-). I have changed them with
SFTOOLS but that did not help - always the same error message.
