envelope - plot min and max data points from a bin of an ERP data file
envelope plotdevice avgfile bin [-save]
envelope reads
the data points from bin bin of the ERP average file avgfile and creates
two temporary files that are used to plot on plotdevice the maximum and
minimum values across all channels in bin bin. The first temporary file
is an ERP average file with two channels: one channel containing the minimum
values and the second channel containing the maximum values. The second
temporary file is a simple ploterps(1)
command file that envelope uses
to plot the two channels. The -save option specifies to save, rather than
automatically delete, the two temporary files (their names will have avgfile
as their base name).
