Adding Data to the Trajectory

Download: example_15_more_ways_to_add_data.py

Here are the different ways to add data to your Trajectory container:

from pypet import Parameter, Trajectory

traj = Trajectory()

# There are more ways to add data,
# 1st the standard way:
traj.f_add_parameter("x", 1, comment="I am the first dimension!")
# 2nd by providing a new parameter/result instance, be aware that the data is added where
# you specify it. There are no such things as shortcuts for parameter creation:
traj.parameters.y = Parameter("y", 1, comment="I am the second dimension!")
# 3rd as before, but if our new leaf has NO name it will be renamed accordingly:
traj.parameters.t = Parameter("", 1, comment="Third dimension")
# See:
print("t=" + str(traj.t))

# This also works for adding groups on the fly and with the well known *dot* notation:
traj.parameters.subgroup = Parameter("subgroup.subsubgroup.w", 2)
# See
print("w=" + str(traj.par.subgroup.subsubgroup.w))


# Finally, there's one more thing. Using this notation we can also add links.
# Simply use the `=` assignment with objects that already exist in your trajectory:
traj.mylink = traj.f_get("x")
# now `mylink` links to parameter `x`, also fast access works:
print("Linking to x gives: " + str(traj.mylink))
