-How to tag it for a project
----------------------------
+How to use?
+-----------
+E.g. for RNA-Seq
```bash
-# ensure there are no pending changes
-# http://stackoverflow.com/questions/5139290/how-to-check-if-theres-nothing-to-be-committed-in-the-current-branch
-git diff --exit-code
-
-# create the tag for current branch
-(cd ${NGS_TOOLS} && test -n "$project" && git diff --exit-code && git tag "${project}__$(date +'%Y%m%d')") || echo "could not tag current branch"
+git clone git@git.mpi-cbg.de:bioinfo/ngs_tools.git /some/where
-# and log it
-git describe --tags >> ${baseDir}/.used_ngs_tools
-
-## since tags are not pushed by default we need to trigger the push
-git push --tags
+export NGS_TOOLS=/some/where
+source ${NGS_TOOLS}/dge_workflow/dge_utils.sh
+export PATH=${NGS_TOOLS}/dge_workflow:$PATH
```
-
-How to create a new version tag
--------------------------------
+Note that the `NGS_TOOLS` variable is required because some of the scripts rely on it for to locate helper scripts.
-1. Create branch:
+VCS model
+---------
-```
-cd /Volumes/projects/bioinfo/scripts/ngs_tools/dev
-git checkout -b v3.23
-git push
-```
+All changes are applied to `master` branch, and project specific tags are created whenever an analysis was done.
-1. Checkout new branch into ngs_tools as stable version
-```
-cd /Volumes/projects/bioinfo/scripts/ngs_tools/
-newVersion=v1.1
-mkdir $newVersion
-cd $newVersion
-git clone git-srv1:/local/git/bioinformatics .
-git checkout ${newVersion}
-
-## prevent from writing
-chmod -R -w ../$newVersion
-```
