moving_x not working to select the data on a specific position with moving window

[Sanjeev273]

I am trying to extract the information of electron bunch using trackParticles diagnostic with moving window. I following fig I want capture the data on marked position.

track_part = S.TrackParticles(species = species_name, chunksize=chunk_size, sort=True, select="all(t>0, (moving_x > 370)*(moving_x < 395)) ", sorted_as="new_tracks", export_dir= save_dir[0], timesteps = [171000, 385000])

Here movig_x not working to select the particle. but other position coordinates are working. There is no change in the result, whether the filter condition applied or not.

Steps to reproduce the problem

As explained in the chat, it appears that your output file is corrupted.

Try using:

    track_part = S.TrackParticles(species=species_name, sort=False,timesteps=timestep).getData()[timestep]
    moving_x   = track_part["moving_x" ]

And then proceed with the analysis using the numpy array moving_x.

If the select strategy does not work because of the corruption of the file, try to make a boolean mask to use with the moving_x array.
