There seems to be a problem with the trajectory output file not correctly showing the uncorrected trajectory. For now, please use the centroid output file from &run_setup. If you run with and without correction, you'll see a difference.

Also, I'd suggest using n_xy_cycles=2 and n_iterations=5, to ensure convergence.

I've confirmed that there is a bug in reporting the uncorrected trajectory. What's actually reported is the trajectory at the end of the next-to-last correction iteration. This will be fixed in the next release.

Thanks for reporting the problem.
