GitHub’s “Organizations” for distributed #bioinformatics dev; migrating from Mercurial’s “Organizations” is a great tool for distributed bioinformatics teams. Here’s how I migrated some of our repositories from Mercurial to Git to take advantage of this feature

After much evangelizing, weeping, and wailing, I finally convinced everyone at one highly geographically and functionally distributed projects that we should at least try consolidating our code in one place.

Currently we have old legacy repositories in CVS, mid-range projects in SVN, new development in Git and Mercurial, and AFAIK a bunch of code in no SCM system at all.

Given that DVCS doesn’t have the directory level granularity of SVN, we definitely don’t want to consolidate everything in a single repository. So far, it seems that GitHub offers the best solution with its “Organizations” feature. This lets a team group multiple repositories under a single umbrella with a shared news feed and administration. Perfect.

hg-git looks like a useful tool if you want to maintain code in both git and mercurial. I don’t. Here’s how I handled a full-scale migration of our repositories:

todd> cd ~/projects
todd> git clone
todd> mkdir new_git_repository ; cd new_git_repository
todd> git init
todd> ../fast-export/ -r ~/projects/old_hg_repository
todd> git checkout HEAD
todd> git remote add origin[organization]/[reponame].git
todd> git push origin master

Bing! And you’re done. Or whatever.
