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).
