Setup your production environment

Install the production scripts

mkdir -P ~/virgo
cd ~/virgo
git clone git@git.ligo.org:morgan.lethuillier/mbta-offline-prod.git prod

You may need to load you ssh key before with

eval $(ssh-agent)
ssh-add $HOME/.ssh/your_prefered_public_key

See this doc for more guidance on how to generate your ssh key and add it to your git account.

Three directories should have been created:

${HOME}/virgo/prod/scripts : some very simple scripts usefull to manage the production
${HOME}/virgo/prod/v5 : main production scripts
${HOME}/virgo/prod/v5/cfg.O4 : mbta skeleton config files

Add the following lines to your .bashrc to add the scripts to your $PATH:

# ------ functions to add or remove a directory to/from the $PATH and avoid duplication
pathadd() {
   newdir=${1%/}
   if [ -d "$1" ] && ! echo $PATH | grep -E -q "(^|:)$newdir($|:)" ; then
      if [ "$2" = "after" ] ; then
         PATH="$PATH:$newdir"
      else
         PATH="$newdir:$PATH"
      fi
   fi
}

pathrm() {
   PATH="$(echo $PATH | sed -e "s;\(^\|:\)${1%/}\(:\|\$\);\1\2;g" -e 's;^:\|:$;;g' -e 's;::;:;g')"
}

# ------ add scripts directory to $PATH
pathadd "."
pathadd "${HOME}/virgo/prod/scripts" after
export PATH

Configure your environment

To configure your environment, you can use setmbta.sh.

source setmbta.sh [LOCAL/CENTRAL]  [MBTA_VERSION]
# example: source setmbta.sh CENTRAL v5r28
# example: source setmbta.sh CENTRAL last

CENTRAL is for a version installed centrally (in /pbs/throng/virgo/virgoApp/).

LOCAL is for a version you have installed locally (in general in ~/virgo/App).

MBTA_VERSION is the name of the mbta version. last corresponds to the more recent version.

The script will configure your environment, and store the paths of the different libraries in $MBTAROOT, $FDROOT, $FRROOT, $FRVROOT, $FFTWROOT…

These paths are then added to your $PATH, $LD_LIBRARY_PATH, $LIBRARY_PATH variables.

With bash autocompletion, you should now have access to most of the Ligo/Virgo executables. For instance try to type Mb + TAB and you will see all the Mbta executables. Or type lal + TAB to see all the lalsuite tools.

To restore your inital path variables, you can unset you environment with:

source unsetmbta.sh

This is done automatically when executing setmbta.sh a second time to definine a new different version of mbta.
