# BVQX file format for *.STC files (Slice Time Course data)
# STC FileVersions supported: 0 (no versioning information yet)
#
# An STC file contains the functional data (time series) of one
# slice of an experimental run. During FMR project creation, as
# many STC files as there are slices will be created. An FMR
# project links to the STC files with an "STCPrefix".
