Hi Rob, I don't really know the answer but instead of "If not I guess I'll have to numpy the problem :-)" I'd rather add a functionality to do this to flex or miller. Pavel On Thu, Apr 11, 2019, 10:00 AM Robert Oeffner wrote:

Hi,

I have a flex.double array of phase values between -360 and 360 degrees I would like to cast them all in one go to lie within 0 to 360. Does anybody know if there is a nice way of doing this with flex arrays? The modulo operator doesn't seem to be supported for flex arrays unlike the +, -, * and the / operators. This would otherwise be handy as I could then convert the array in one line of code like

phases = phases % 360.0

If not I guess I'll have to numpy the problem :-)

Many thanks,

Rob

Will flex.fmod_positive help here, e.g.: """Modify the calculated phi values so that they match the full rotation from zero taken from the the observations, rather than being modulo 2*pi.""" x_obs, y_obs, phi_obs = reflections["xyzobs.mm.value"].parts() x_calc, y_calc, phi_calc = reflections["xyzcal.mm"].parts() resid = phi_calc - (flex.fmod_positive(phi_obs, TWO_PI)) # ensure this is the smaller of two possibilities resid = flex.fmod_positive((resid + pi), TWO_PI) - pi phi_calc = phi_obs + resid https://github.com/dials/dials/blob/c8692c36577ac3e8b1410e78b6ede7f4e8300392...
