7.1.21. 1dnorm

Link to classic view

Usage: 1dnorm [options] infile outfile where infile is an AFNI *.1D file (ASCII list of numbers arranged in columns); outfile will be a similar file, with each column being L_2 normalized (sum of squares = 1). * If ‘infile’ is ‘-‘, it will be read from stdin. * If ‘outfile’ is ‘-‘, it will be written to stdout.

Options:

-norm1 = Normalize so sum of absolute values is 1 (L_1 norm)
-normx = So that max absolute value is 1 (L_infinity norm)
-demean = Subtract each column’s mean before normalizing
-demed = Subtract each column’s median before normalizing
[-demean and -demed are mutually exclusive!]
