title: Reply to "Comment on 'A study on tetrahedron-based inhomogeneous Monte-Carlo optical simulation'".
abstract: We compare the accuracy of TIM-OS and MMCM in response to the recent analysis made by Fang [Biomed. Opt. Express 2, 1258 (2011)]. Our results show that the tetrahedron-based energy deposition algorithm used in TIM-OS is more accurate than the node-based energy deposition algorithm used in MMCM.
