Research Blog
Welcome to my Research Blog.
This is mostly meant to document what I am working on for myself, and to communicate with my colleagues. It is likely filled with errors!

Now that I have switched to using Rockstar for the halo finder, I am going to use consistent trees for the merger trees (this is required to get \(V_{\rm peak}\) for the abundance matching step).
I downloaded the code and ran make.
(When trying to install on my laptop I ran into problems with gcc compiler, but fixed it by specifying the compiler in the file src/Makefile (I set CC = gcc-10))
Go to the folder with the config file (mine was rockstar_param.cfg). Make sure OUTBASE is where halofinder output is, and that NUM_SNAPS and STARTING_SNAP are set properly.
Then, run
perl /path/to/rockstar/scripts/gen_merger_cfg.pl rockstar.cfg
and follow the instructions.
On Pleiades, I can run submit a job script to run the trees:
#PBS -S /bin/csh
#PBS -j oe
#PBS -l select=1:ncpus=1:mem=100MB
#PBS -l walltime=2:00:00
#PBS -q ldan
