If you get this
remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com. remote: error: Trace: 7d51855d4f834a90c5a5a526e93d2668 remote: error: See http://git.io/iEPt8g for more information. remote: error: File coverage/sensitivity/simulated.bed is 102.00 MB; this exceeds GitHub's file size limit of 100.00 MB
And want to remove it from your branch commits, do this.
git filter-branch --tree-filter 'rm -rf path/to/your/file' HEAD git push
