Any project ends up in a repository with an annex (DataLad dataset) (10%)

Manage pdfs of research papers (11%)

Distribution and archival of build products (6%)

Biomechanical testing and computer modeling of knee meniscus injury. Git annex was used to track experimental data and store snapshots of analysis. Regular git was used in the same repository to track code, notes, and drafts. Work supported by NIH grants R01AR050052, R01EB002425, R21AR070966, U54GM104941. (1%)
