  • Description
  • Computes the Quade test (non-parametric test) on TF files (.tf). It allows to compare many conditions with paired subjects.
    The Quade test is a nonparametric two-way analyses of variance. It is equivalent to an ANOVA with 1 factor, paired subjects and many conditions.

  • Usage
  • tfavgquade

This program uses an interactive input.The questions are as follows (questions (program) are italic, answers (user) are bold):
Number of conditions :
3
Number of files per condition :
10
Conover 2 by 2 comparisons : probability threshold (e.g. 0.01) :
0.01
Baseline correction: none (0), mean (1) or median (2) value on a time-window? (0/1/2)
1
Start latency for baseline correction (in ms.) :
-500
Stop latency for baseline correction (in ms.) :
-50
Subtract (1) or divide (2) by baseline ? (1/2)
1
Input file name 1 in condition 1 (with extension) :
tffile1cond1.avg.tf
Input file name 2 in condition 1 (with extension) :
tffile2cond1.avg.tf
...
Input file name 1 in condition 2 (with extension) :
tffile1cond2.avg.tf
...
Input file name 10 in condition 3 (with extension) :
tffile10cond3.avg.tf

Output file prefix for p, F and Conover values (without extension) :
quade_tf

  • Fields of parameter file and example

  • Examples

  • Comments
    1. All TF files should be compatible (in terms of number of channels and samples, number of pre-stimulus samples, sampling frequency) to the first TF file (file 1 in condition 1).
    2. In output Conover TF files, only significant values are stored in file (positive values). The others are replaced by 1.
