Hi, I'm calling ft_timelockanalysis within a method in a class object called plxReader. When called from the commandline there is no errors but when the same commad is called from the function I get the following error: Invalid field name: 'plxReader.ftAnalysis'. Error in warning_once>fieldnameFromStack (line 196) ft_previous_warnings.(stack(end).name) = []; % iteratively build up structure fields Error in warning_once (line 123) [tmpfname ft_default.warning.identifier line] = fieldnameFromStack(ft_default.warning.identifier); Error in ft_postamble_history (line 55) warning_once('-clear'); Error in ft_postamble (line 55) evalin('caller', ['ft_postamble_' cmd]); Error in ft_timelockanalysis (line 371) ft_postamble history timelock Error in plxReader/ftAnalysis (line 213) av{i} = ft_timelockanalysis(cfg,ft); The class.method name in the stack causes the error.

I've fixed this for my needs by the following: diff --git a/utilities/private/warning_once.m b/utilities/private/warning_once.m index 33f9f27..d930ef2 100644 --- a/utilities/private/warning_once.m +++ b/utilities/private/warning_once.m @@ -193,7 +193,8 @@ end fname = horzcat(stack(end).name); if ~issubfield(ft_previous_warnings, stack(end).name) - ft_previous_warnings.(stack(end).name) = []; % iteratively build up structure fields + name = regexprep(stack(end).name,'\.',''); + ft_previous_warnings.(name) = []; % iteratively build up structure fields end

Hi Ian, thanks for reporting and providing a tentative fix. I'll look into this now and will report back on how we solved this :) *** This bug has been marked as a duplicate of bug 2407 ***

fixed in a slightly more generic way by fname = regexprep(fname,'[^a-zA-Z0-9]',''); thanks very much for reporting this!
