Instructions

VAST (Volume Annotation and Segmentation Tool) is a utility application for manual annotation of large EM stacks.

The VAST Lite executable and other files on this page are provided free of charge and may be distributed freely, but not sold. Commercial usage is allowed. For more information please see the VAST Lite manual.

The executable contains a supplementary files package which it can write to disk. The package includes a documentation PDF, the VastTools Matlab scripts for extended functionality, and .vsvr files which provide immediate access to some large online data sets.
