Is it possible to calculate quantities for trackers that depend on their host halo properties?

1

Hi, I have a question on the best-use of trackers and whether it is possible to compute properties for them that depends on other halo properties. For example, I have...

Since PR #88, importing properties precomputed by halo finders through https://github.com/pynbody/tangos/blob/f887de11faf413b5eccf16a3ef50266105b2e577/tangos/input_handlers/__init__.py#L101-L110 has changed behaviour, requiring yielding first `finder_offset`, second `finder_id` and then the array of properties to be imported.

Tangos Importing of properties does not check if properties already exist?

2

When using the `tangos import-properties` command multiple times, Tangos duplicates the properties without checking whether they are already in the database. This is the opposite behaviour to `tangos write`, where...

Numpy compatibility

1

I faced an error today which I am posting here as a reference/documentation. I (by mistake) generated a database storing numpy arrays with numpy 1.16. When retrieving the properties through...

Notifying implementation inconsistency in user properties

Hi, I am getting an unexpected error following my calculation of the SFR_histogram for a single halo at the latest timestep: 'tangos write SFR_histogram SFR_10Myr --for Halo600 --latest --hmax=0'. The...

How to use filter/mask with calculate_all() ?

Hi all, I am in situation where I would like to calculate a property for all halos in a timestep that satisfy a condition on a different property (all halos...

Is it possible to add halos to an existing simulation ?

1

This is more a question than an issue. Let's say I have a database with an already built simulation with halos containing more than 500 particles in each timestep. I...

Issue when trying to remove a simulation

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...

Resume calculation interactions with --force

2

Hi, I have greatly appreciated the new features for restoring runs (#245) which have been a big timesaver for HPC tangos applications. They however interact unexpectedly with the `--force` keyword....

Detecting conformal time in Ramses

Hi, I am having issue with the automated detection of conformal/proper time for a Ramses snapshot. The snapshot is correctly flagged as a cosmological run, the RT fields are detected,...
