NAME

EWThreshold.pl - Calculate the Experimentwise Threshold from a permutation test

SYNOPSIS

  EWThreshold [-s size] [-h]   < input  > output

DESCRIPTION

EWThreshold.pl reads from the standard input and writes to the standard output. It reads the results of permutation test that are in the format of ZipermE.out. It sorts the likelihood maxima from that file and prints out the 100(1 - size)th percentile.

OPTIONS

-s

This option requires an a real value. It should be the size of the test, that is the Type I error probability. The default is 0.05.

-h

requires no operand. If used, it prints a usage message and exits.

EXAMPLE

After running the example outlined in the GetMaxLR manpage, you can run

        % EWThreshold.pl -s 0.01 < corn.z3.e

to get the experimentwise threshold for a 1% test. The threshold will be printed to the standard output.
