Hello,
I have been trying to do restrained refinement on a dataset I integrated and scaled in HKL2000, then converted to a .mtz file using both scalepack2mtz and sftools. After molecular replacement in Phaser, the rigid body refinement in Refmac5 works, but when I later attempt a restrained refinement I get the error "child killed: floating point exception." If anyone has any idea of how I should go about fixing this problem, I'd greatly appreciate it. Thanks, Ray
