Thanks for the advice. What ultimately worked was going back to CCP4 6.1.3. I was able to use the Scalepack to MTZ in that version and it handled the R -3 (SG 148) just fine. I was able to use the MTZ from 6.1.3 in the current release 6.3 and phaser and refmac ran fine. So the issue was in the way the new scalepack to MTZ handles SG 148.
