Analysis and visualization toolkit for AMIGA cosmological simulation software.
HaloAnalyzer is a data analysis package for the AMIGA cosmological simulation toolkit, found online at http://popia.ft.uam.es/AMIGA/. This software suite is designed specifically for analysis of the output of AMIGA HaloFinder tool, and uses the AMIGA MergerTree and HaloHistory tools as well. The suite is written mostly in object Perl, with some interesting external utilities for two-point correlation and 3D visualization written in C and C++, respectively.
Some examples of the capabilities of this suite:
- Run AMIGA MergerTree and HaloHistory with one line of code, with no information needed from the user.
- Get all halo data in a convenient hash table indexed by redshift.
- Trace changes of halo index through redshift
- Retrieve history of any halo.
- Calculate mass evolution of all halos.
- Find formation times of halos in user specified histogram format.
- Find shared particles between halos of neighbouring redshifts.
- Construct graphical halo merger trees (see e.g. http://adsabs.harvard.edu/abs/2010A%26A...522A..92E)
For full documentation, see the docs/ directory. The documentation for all Perl code is generated from the code itself via the POD tool, and can be regenerated by running the docs/makedocs.sh script. Documentation for the C/C++ programs is written in separate .pod files.
The C/C++ code is provided together with Makefiles, which require the GNU Make program and the Gnu Compiler Collection C/C++ compiler (gcc/g++) to compile . These Makefiles may or may not work for your system. Adjusting them to your liking is advised.
