i noticed phaser splits the rotation onto 2 threads - just wondering why that might be, since i used nproc=4 on the command line.... Which program are you running, phenix.phaser or AutoMR?

phenix.phaser - it is clearly "Spreading calculation onto 2 threads".

Phaser doesn't have an nproc keyword - so it is probably using some default setting. In CCP4 syntax, the directive you want is this: JOBS 4 You could also try setting the environment variable OMP_NUM_THREADS - but I'm not sure if that will have any effect on Phaser. -Nat
