#################################  Useful command lines  ################################# 
#
#
## 1) Build RSAT Docker container
#
# export RSATDOCKERVERSION=`date '+%Y%m%d'` 
# docker build --tag rsat:$RSATDOCKERVERSION --tag rsat:latest --force-rm --compress .
# 
#
## 2) Create local folders for input data and results, outside the container, as these might be large
#
# mkdir -p ~/rsat_data/genomes ~/rsat_results
# chmod -R a+w ~/rsat_data/genomes ~/rsat_results
# 
#  
## 3) Launch Docker RSAT container:
#
# docker run --rm -v ~/rsat_data:/packages/rsat/public_html/data/ -v ~/rsat_results:/home/rsat_user/rsat_results -it rsat:latest
#
#
## 4) Download organism from public RSAT server, such as the Plants server.
##    Other available servers: http://fungi.rsat.eu, http://metazoa.rsat.eu, http://protists.rsat.eu
# 
# download-organism -v 2 -org Prunus_persica.Prunus_persica_NCBIv2.60 -server https://rsat.eead.csic.es/plants
#
#
## 5) Test container
#
# cd rsat_results 
# make -f ../test_data/peak-motifs.mk RNDSAMPLES=2 all
#
#
## 6) Install any organism, please follow 
##    https://rsa-tools.github.io/managing-RSAT/genome_installation/install_organisms_FASTA_GTF.html
#
# 
## 7) To connect to RSAT Web server running from Docker
#
# If you run Docker as a normal user Apache will not start properly and you will see these messages:
#
#   * Starting Apache httpd web server apache2
