This page is provided for FreeSurfer developers to assist in the CVS -> git transition. Git is a feature loaded version control system which at times can be a bit of a hurdle to learn. However, when used in its simplest form it is very similar to most all other version control systems, including CVS. This page will give the basic CVS commands used by most FreeSurfer developers the git equivalent of that command.

Initial Git Setup

When we start out using git we want to set a few of our configuration settings. We only need to do this one time:

$> cd ~
$> git config --global user.name "Zeke Kaufman"
$> git config --global user.email zkaufman@nmr.mgh.harvard.edu

For additional examples of git specifics setting (e.g. default editor, color settings), see the following page: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration

Checkout out the main branch

When working with CVS, we would checkout out the FreeSurfer repository using the cvs checkout dev command. In git we 'clone' repositories. This gives us a local version of the repository which we can work with.

$> git clone /space/freesurfer/repo/freesurfer

Checkout the stable branch:

$> git clone -b stable6 /space/freesurfer/repo/freesurfer

$> cvs checkout -r stable6 dev

Daily Workflow

Commit a modified source code file:

cvs

cvs commit -m "Added new capabilities." <file_name>

git

git commit -m "Added new capabilities." <file_name>

git push

Modify and commit a data file:

cvs

cvs commit <file_name>

git

git annex unlock <file_name>

git annex add <file_name>

git commit <file_name>

git push

git annex copy --to origin <file_name>

Add a data file:

cvs

cvs add <file_name>

cvs commit <file_name>

git

git annex add <file_name>

git commit <file_name>

git push

git annex copy --to origin <file_name>

Remove data file:

cvs

rm <file_name>

cvs rm <file_name>

cvs commit -m "Removing <file_name>" <file_name>

git

git rm <file_name>

git commit -m "Removing <file_name>" <file_name>

Undo 1 commit (before push):

git

git reset --soft HEAD~1

Undo 2 commits:

git

git reset --soft HEAD~2
