A package for simulating cres data.
Project description
he6_cres_spec_sims
A package for simulating cres experiments over a variety of magnetic field values.
Simulate an experiment then make interactive plots of cres track features!
Instructions for running simulations on CENPA cluster (rocks):
-
Get dependencies:
- Instructions:
- Log on to rocks.
cd /data/eliza4/he6_cres/simulation/
pip3 install -r he6-cres-spec-sims/requirements.txt --user
- Notes:
- May need to upgrade pip for the above to work on rocks.
- For Winston and I this worked:
pip3 install --upgrade pip
- For Winston and I this worked:
- The following should contain all necessary python packages but if that isn't the case please let Drew Byron know.
- Be sure to add the
module load python-3.7.3
to your enviornment setup file or .bash_profile file so that you have access to python3. - The above must be done by each user, as it's the current users python packages that the scripts below will be utilizing.

cd /data/eliza4/he6_cres/simulation/he6-cres-spec-sims
- Set up:
- Before running an experiment one needs a
.json
experiment config and a.yaml
base config to both be in the following directory on rocks:/data/eliza4/he6_cres/simulation/sim_results/experiments/
. (TODO: Document the config files and the output fields.) - Here is how I copy those over from the examples shown in the repo (
he6-cres-spec-sims/config_files
). You should be able to do the same with minimal adjustment of paths.!scp /home/drew/He6CRES/he6-cres-spec-sims/config_files/rocks* drewbyron@172.25.100.1:/data/eliza4/he6_cres/simulation/sim_results/experiments
- Before running an experiment one needs a
- Initial run:
./he6_cres_spec_sims/run_rocks_experiment.py -exp "/data/eliza4/he6_cres/simulation/sim_results/experiments/rocks_exp_config_example.json"
- Clean-up:
./he6_cres_spec_sims/run_rocks_experiment.py -exp "/data/eliza4/he6_cres/simulation/sim_results/experiments/rocks_exp_config_example.json" -clean True
- Notes:
- Initial run:
-exp
(str): Specify the path to the json file that contains the specific attributes (in the form of a python dictionary) of the simulated experiment. See the docstring for therun_rocks_experiment.py
module for a complete description of all attributes that the.json
must contain.- Say one made a
.json
experiment config locally based on some queries to the he6 postgreSQL database. You could copy that to the rockssim_results/experiments
directory with a command like this:!scp /media/drew/T7\ Shield/spec_sims_results/rocks_experiments/exp_demo_nov2022.json drewbyron@172.25.100.1:/data/eliza4/he6_cres/simulation/sim_results/experiments
- Here
experiment_copies
number of independent (unique random seeds) but otherwise identical experiments are run over rocks. The experiment attributeexperiment_copies
is specified in the.json
config file. It is parallelized such that each field specified in each copy is sent to a different node. So for example if the.json
config had these attributes:{"experiment_copies": 5, "beta_num": 1000, "fields_T": [1.0, 2.0, 3.0]}
, then 5 copies x 3 fields = 15 nodes would each simulate 1000 betas.
- Clean up:
- In the clean-up phase the different copies of the experiment that are produced by the run are combined into one directory that can then be copied onto a local machine for analysis.
- In the example used above where we have 5 copies of an experiment spanning 3 fields each with 1000 betas simulated, all of the resultant
.csvs
containing track info for the 5 copies is combined into one directory.
- General:
- The logs will get very clogged up with different
.txt
files. Occassionally just delete the contents ofsimulation/sim_logs
.

- Use the class
SimulationResults
from theresults.py
module (need to have a local copy of the repo) to grab the experiment results. - Example code to be run in ipynb or within a script:

Documentation for simulation config files:
Experiment config (.json)
Description:
The most basic function of the simulation package is to simulate betas in a given trap depth and main field. An "experiment" is a set of individual simulations run together with organized output. This makes it easy to simulate something closely resembling our experiments; running at a range of trap depths and main field values. The .json
experiment config serves as the instructions for which simulations to run in the experiment.
One can find an example of this config file here: /he6-cres-spec-sims/config_files/rocks_exp_config_example.json
. Note that the name the experiment directory is assigned is the name of the .json
experiment config file.
An example of it's contents:
{
"experiment_copies": 3,
"base_config_path": "/data/eliza4/he6_cres/simulation/sim_results/experiments/rocks_base_config_example.yaml",
"isotope": "He6",
"events_to_simulate": -1,
"betas_to_simulate": 1e2,
"rand_seeds": [4062, 3759, 3456, 3153, 2850, 2547, 2244, 1941, 1638, 1335, 1032],
"fields_T": [3.25, 3.0, 2.75, 2.5, 2.25, 2.0, 1.75, 1.5, 1.25, 1.0, 0.75],
"traps_A": [1.8, 1.661538, 1.523077, 1.384615, 1.246154, 1.107692, 0.969231, 0.830769, 0.692308, 0.553846, 0.4153845]
}
Explanation of the required fields:
-
experiment_copies:
- Number of copies to be run of the experiment. This field must be omitted if running locally. When running on the cluster the simulations are parallelized such that each field specified in each copy is sent to a different node. So for example if the
.json
config had these attributes:{"experiment_copies": 5, "beta_num": 1000, "fields_T": [1.0, 2.0, 3.0]}
, then 5 copies x 3 fields = 15 nodes would each simulate 1000 betas. Then the clean-up phase would combine these all into a directory whose name matches the.json
config name.
- Number of copies to be run of the experiment. This field must be omitted if running locally. When running on the cluster the simulations are parallelized such that each field specified in each copy is sent to a different node. So for example if the
-
base_config_path:
- Full path to the base_config. See instructions above for details on where to put the base config. See documentation below for the required fields of the base config.
-
isotope:
- Which isotope to simulate. Currently only works for "Ne19" and "He6" but could easily be extended to other isotopes.
-
events_to_simulate:
- Number of trapped events to simulate. When not set to -1 the simulation will terminate when events_to_simulate betas have been trapped. If set to -1 then the simulation will be terminated once betas_to_simulate have been simulated (trapped or not). One of events_to_simulate or betas_to_simulate should be -1.
-
betas_to_simulate:
- Number of betas simulated per experiment. See description of events_to_simulate above for details.
-
rand_seeds:
- List of ints used as the random seed in a simulation; one for each simulation to be run. The lists rand_seeds, fields_T, and traps_A, must all have the same length.
-
fields_T:
- List of magnetic fields to simulate in Tesla. The lists rand_seeds, fields_T, and traps_A, must all have the same length.
-
traps_A:
- List of trap currents to simulate in Amps. The lists rand_seeds, fields_T, and traps_A, must all have the same length.
To build your own .json
config:
- Query the he6-cres database to get real experiment conditions (field, trap depth, isotope).
- Build a python dictionary:
my_exp_dict
that contains all required fields. import json
json.dump(my_exp_dict, 'path_to_exp_dict.json')
Base config (.yaml)
Description:
The base configuration .yaml
file contains the specific parameters to use for each "block" of an individual simulation. When running an experiment, certain settings are over-written (like the betas_to_simulate
) by the .json
experiment config. But the general settings defined in the .yaml
base config are used across all fields and trap depths defined in the .json
experiment config.
One can find an example of this config file here: /he6-cres-spec-sims/config_files/rocks_base_config_example.yaml

Important notes:
- In case of emergency please break the glass. No actually just email me at wbyron@uw.edu.
- The
develop
branch is tested and working on rocks and locally as of 11/16/22.
Development in Progress:
To Dos (11/18/22):
- Make docstrings for all modules/methods!
- Test a rocks run with a lot of stats to see what breaks.
- Work on documenting the modules (quickly) with docstrings.
- Then move on to making sure that katydid on rocks still works without the pip install. For now I am uninstalling the package with a pip uninstall. This will break katydid on rocks!! So I need to go fix that once I'm done with this
Tests:
- Testing 1e4 betas for 11 fields with 10 copies at 8:49 AM 11/18/22.
- This worked. We get some betas that fail in that the b_avg is zero, so the integral must fail. Though it resulted in over 5 million rows and 45 columns.
