 Hi Claudia,

You seem to have these operators:

(x ,y,z)

( x-34/68, -y+13/79, -z +20/90) [ a 2 fold screw axis along a]

( -x +75/68, -y-26/79, z+9/90)  [stumped]

(-x+38/69, y-38/79, -z+24/90) [ two fold screw along b ]

(x+9/69, y-28/79, z-46/90) [pseudo translational symmetry]

(-x+57/69, y+10/79, -z+63/90) [stumped]

(-x + 86/69 , -y + 6/79 , z - 48/90) [ two fold screw along c ]

(x-53/69, -y-36/79, -z + 61/90 ) [stumped]

Are you sure that it is not P212121 with a pseudo tranlstaional
symmetry or two fold NCS parallel to one of the screws?

In any case, P1 is bad news, because phenix.refine cannot handle more
then two twin domains. I suggest going to all flavours of P2 ( P112x,
P12x1, P2x11) if you are absolutely sure about the sg  not being p222
or so.

Did you run xtriage?
