Dear All,

I am new to OPAL. I use the example code "RingCyclotron.in" with "PSDUMPFREQ = 250", "turns = 5", "nstep = 2000", and "NPART = 1e2". I want to load the phase space data (x,y,z) in different time steps for a bunch.

I use the following code in pyOPALTools:

------------------------------------------------------------------------

from opal import load_dataset

ds = load_dataset('./', fname='RingCyclotron.h5')

x = ds.getData('x')

y = ds.getData('y')

z = ds.getData('z')

------------------------------------------------------------------------

From the above script, it (x,y,z) only comes out the initial bunch data. Is any method to load phase space data in different time steps? Or the setting is wrong?

Best regards

Siao-Cing Liou
