repeated Measure ANOVA with two independant group in LIMO

[jaktherenegade]

Description

I find a bug in the limo_random_select.m script

#### Steps to Reproduce

1. Specify a mix design with a within and a between factor
2. Estimate the parameter (channels) for the first level
3. call the limo_random effect (in the GUI : Study ->LInear MOdeling of EEG data->2nd level Analysis
4. Specify an ANOVA/ANCOVA with repeated mesure, group = 2, condition = 2, after le selection of the Beta_files_Gp-2 (in first as required) you have a error message in the command window (see below)

#### Expected behavior: Open a windows to sepcify the level of the within factor to consider
#### Actual behavior: Error message in the command window

Unrecognized function or variable 'parameters'.

Error in limo_random_select (line 1301)
parameters(i,:) = parameters(1,:); % copy design for other groups
^^^^^^^^^^^^^^^
Error in limo_random_effect>ANOVA_Callback (line 338)
limo_random_select(answer,handles.chan_file,'nboot',handles.b,'tfce',handles.tfce,'type',handles.type);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in gui_mainfcn (line 95)
feval(varargin{:});
^^^^^^^^^^^^^^^^^^
Error in limo_random_effect (line 28)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)limo_random_effect('ANOVA_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

#### Solution At the line 1273 of the scipt limo_random_select.m, replace : for i=gp_nb:-1:1 by for i=1:1:gp_nb (change the order of the incrementation) and it solved the problem.
#### Versions

OS version	[Windows 11]
Matlab version	[2024b]
EEGLAB version	[2023.1]
LIMO version	[4.1.2]

@CPernet can you help?

I wonder if it is a GUI related issue? Via script it does not bug 🐛 - FYI running loops backward avoid overloading memory (equivalent declaring in advance all variables of size gp_nb)
