scalpnorm reads the data from stdin and writes the normalized data to stdout. Factors are listed in order from slowest moving to fastest moving. Subjects are the fastest moving factor, and scalp sites are the next fastest moving factor in both input and output. Thus, if you had 3 conditions, 26 electrodes, and 5 subjects as input (subjects fastest moving factor, electrodes next fastest, conditions slowest), the command line would be:
If you had 3 conditions, 2 sub-conditions, 26 electrodes, and 5 subjects, the command line would be:
In the first example, there are 3 x 5 = 15 normalizations performed; in the second example, 3 x 2 x 5 = 30 normalizations are performed.
