Dear Cyril Pernet and Arnauld Delorme,

First and foremost, thank you for creating such invaluable tools. I am currently conducting an experiment where I aim to compare 3 different conditions based on events occurring within specific blocks.

I am utilizing LIMO 4.0 within EEGLAB 2023.1 for this analysis. In my STUDY, there are a total of 5 event markers which I have categorized into three groups: Fix, OMS&pump&stop, and Cashout&pop. I intend to perform a Repeated Measures ANOVA on data from 42 participants to examine any differences between these conditions. As my work is closely aligned with the tutorials provided, I have been following the tutorial steps:

Precompute Run ERP calculations in pop_limo() with the following parameters: pop_limo(STUDY, ALLEEG, 'method','WLS','measure','daterp','timelim',[-150 650] ,'erase','on','splitreg','off'); Proceed to 2nd level analysis -> check on 'Precompute statistics' -> Select ANOVA/ANCOVA -> Repeated Measures ANOVA -> 'Continue' for group information (only one group) -> Enter repeated factors level {Factor 1 : BART(name) : 3(Number of values)} -> Beta -> pick a 1st level analysis file 'ok' -> pick one or more beta parameters below 'select 1~6(except constant)' After performing these steps, I encounter the following error message:

Index exceeds the number of array elements. Index must not exceed 1.

Error in limo_random_select>reorganize_params (line 2304)
str = ['Reorganize values as needed: ' factorname{1} '=rows and ' factorname{2} '=columns'];

Error in limo_random_select (line 1335)
                    paramTmp        = reorganize_params(parameters(i,:), betas,factor_names, factor_nb);

Error in limo_random_effect>ANOVA_Callback (line 262)
            limo_random_select(answer,handles.chan_file,'nboot',handles.b,'tfce',handles.tfce,'type','Channels');

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in limo_random_effect (line 36)
    gui_mainfcn(gui_State, varargin{:});

Versions

OS version	window10.0
Matlab version	2022a
EEGLAB version	2023.1

Could the issue stem from incorrect input regarding the number of factors or beta parameters? I would appreciate your insights into resolving this matter.

Best regards, Bong

I am sorry. I done this with selecting each con file instead of beta.

Would you mind to share your study so we can try running the commands and see what's wrong? thanks

[CPernet]

it's the factor name issue we have fixed it in this version of limo_random_select

OK, closing for now. Feel free to reopen.
