I would be tempted to say that you don't need to combine; with 1.7 A
data, refinement should do it with no trouble.
And, yes, of course ARP/wARP (7.0) would be the best way to do it ;-)
If you want to combine though, I use the molrep phases to get all
heavy atoms
in an anomalous fourier map, then go to SHARP with these sites and
use the 'External phases' option
in the SHARP gui. Works well for me.
I also recall that Phaser has an option for exactly do that, but with
SAD data only.
But, again, if you have 1.7 A data good old refinement and auto-
building will (likely) do the job in a glance.

PS If you dont want to install arp/warp locally why not try:

PS2 Apologies for the shameless promotion of ARP/wARP ;-)
