snap2sarc - converts Snapshot archive to slab3d archive. [ hp, hm ] = snap2sarc( snapSubject, cleanmap, sarcName ) subject - Snapshot archive subject name (see arclist) cleanmap - 'clean' map (see below) sarcName - if present, saves sarc to file (do not include .sarc extension) hp - processed data slab3d archive struct hm - measured data slab3d archive struct Regarding cleanmap: The Snapshot archive 'map' var can be created from head tracker data. The tracker map is stored in the sarc 'tgrid' field. Since the tracker data can contain errors, you must also provide a 'clean' map (i.e., intended locations (see newmap())). The clean map is stored in the sarc 'dgrid' field. To determine the newmap parameters, use arcload() to load the Snapshot archive and type 'map' to view the map variable. NOTE: Snapshot maps are grouped-by-elevation! slab3d, tron, AHM, and sarc are grouped-by-azimuth.
