Issue when trying to remove a simulation

[Martin-Rey]

When trying to remove a simulation a simulation form the database (command tangos rm tutorial_ramses), I get the following error :

File "/Users/mrey/Documents/tangos/tangos/scripts/manager.py", line 189, in rem_simulation_timesteps
print(term.RED + "Delete simulation", sim, term.NORMAL)
TypeError: can't concat str to bytes

from https://github.com/pynbody/tangos/blob/master/tangos/scripts/manager.py#L189

I am struggling to understand exactly what is going on.

Removing a simulation is not currently supported. The facility should be removed until it can be reimplemented correctly.

In the meantime, you could investigate the rollback command instead. tangos recent-runs 5 should show you the five most recent groups added to the database, for example, then you can roll them back by giving the ids to rollback.

The ability to delete a simulation has now been removed. It should be reintroduced in a future release so I will leave this PR open.
