- OPT: sct_register_straight_spinalcord_to_template has now been replaced by sct_register_multimodal in sct_register_to_template.
- OPT: major improvements for sct_dmri_moco, including spline regularization, eddy correction, group-wise registration, gaussian mask.
- OPT: sct_check_dependencies.py can now output log file and do extensive tests (type -h for more info)
- NEW: sct_apply_transfo.py: apply warping field (wrapper to ANTs WarpImageMultiTransform)

- NEW: virtual machine
- BUG: fixed sct_check_dependencies for Linux
- BUG: fix VM failure of sct_register_to_template (issue #41)
- OPT: sct_register_to_template.py now registers the straight spinal cord to the template using sct_register_multimodal.py, which uses the spinal cord segmentation for more accurate results.
