stim_type barnoise # Spatial grid white-noise stimulus
stim_samp 1000.0 # Stimulus sampling rate
st0 0 # Stimulus start time (s)
stn 10 # Stimulus duration (s)
cx 0 # center location (deg)
cy 0 # center location (deg)
nbar 48 # number of bars
bar_width_pix 4 # bar width (pix), or use "bar_width 0.1 # (deg)"
bar_length 20.0 # bar length (deg)
border 1.0 # Distance (pix) from bar borders for anti-aliasing
direction 45 # orientation of bars (0..360 deg)
# NOTE, This 'direction' becomes an offset if
# 'mask_direction' instead of 'mask_dir_offset'
# is used below.
distrib 2 # 2-binary, 3-ternary

#
# These parameters allow the addition of a moving mask pattern
