NERA is an application which manage databases for Monte Carlo simulations.

We often have troubles in managing huge amount of data obtained by Monte Carlo simulations.
Treatment of various simulation models, various parameter sets, and many independent runs are often necessary.
Classifying the result data into folders, keeping a note of what we have done, creating figures by the data, etc., are too messy to do by hand.
NERA is being developed aiming at resolving these situations.
NERA helps you to manage databases and to concentrate on scienctific parts of your research.


sudo gem install nera

The basics

To create a database “my_db”,

 nera my_db 

The nera command starts an interactive cui-based program.

If you want to add a simulation model to “my_db”,

 nera_addsim my_db 

To edit host information,

 nera_addhost my_db
