===== PE run steps =====

==== Build frame files ====

  - Run <code>source /home/spxfp1/rhys_cory/frames/python_env </code>
  - access make-zero-noise-frame.sh file from [[https://github.com/hoyc1/Precession/blob/master/files_for_pe_runs/make-zero-noise-frame.sh | Charlie's Github]] 
This file uses pycbc_generate_hwinj to generate the waveform to be injected and pycbc_insert_frame_hwinj for the injection (see documentation [[https://ligo-cbc.github.io/pycbc/latest/html/hwinj.html?highlight=pycbc_insert_frame_hwinj#generate-waveform-from-command-line-pycbc-generate-hwinj | here ]] )
 
  - Edit /make-zero-noise-frame.sh. Edit any parameters that are you want to simulate. Finally, there is the place to set the path to where you will want to store the *txt's and *gwf's you create and store the files you produce in there.  This is also where you will perform your PE run.
  - Run <code> . make-zero-noise-frame.sh </code>
  - At this point frame files should be created which correspond to the waveform at each detector
  - type deactivate to remove the source ready to source the code for the pe runs

Once these steps are done, prepare the pe file
==== Prepare PE.ini file ==== 
  - Go to directory containing Frame File
   Source all the code installations: <code>source /home/spxfp1/opt/lalsuite/lalinference_o2_phenomHM/etc/lalsuiterc </code>
  - Source .ini file from [[https://github.com/hoyc1/Precession/blob/master/files_for_pe_runs | Charlie's Github]], The ini file will (currently will change this eventually) depend on whether you are doing nest or mcmc and how many detectors
  - In ini file modify webdir, baseurl and email, can modify other parameters as necessary
In general, if you want to know what a parameter means, refer to [[https://www.lsc-group.phys.uwm.edu/ligovirgo/cbcnote/ParameterEstimationModelSelection/LALInference_HowTo|this page]] and/or read the outputs of <code>lalinference_mcmc --help
lalinference_nest --help </code>

==== Run PE.ini file ==== 

  - Parse your "inifile" to setup the run: <code> lalinference_pipe PE.ini -r ./ </code>
  - Follow instructions, if any appear i.e. run <code> condor_submit_dag multidag.dag </code> At which point, your run should be started.
  - To monitor your run do: <code>condor_q $USER </code> or <code>watch condor_q $USER </code>
