[Eeglablist] threshold option in std_plotcurve

[Becker, Susanne]

Dear Makoto,

thank you very much for our help. I’ll report the problem to the EEGLAB Bugzilla in a second.

I checked the length of 'Rregions‘ and ‚g.val2mask‘ using the debug mode. They are of the same length, both 150 columns with 2 lines each. However, I don’t know if it is relevant, I saw that ‚g.maskarray‘ is also 150 columns long but has only one line. Might this somehow related to the error?
If I just run the line (in debug mode):
find(g.val2mask < g.maskarray)

I get this error mask, i.e. the same as when running the std_plotcurve command.
Error using  <
Matrix dimensions must agree.

Thanks
Susanne

Dear Susanne,

Sorry for the trouble.
Could you report it to EEGLAB Bugzilla by filing the case? Those reports submitted here will be directly read by developpers.

I appreciate your patience and cooperation.

Meanwhile, for the initial diagnosis... judging from the error message, 'Rregions' and 'g.val2mask' seem to have different length. Can you identify the size of these variables by using debug mode? If you can do it and the error is obvious, we may be able to solve it by ourselves.

Makoto

Dear all,

I’m using the std_plotcurve function to plot ERPs in two different conditions. I wanted to used the option „threshold“ with 0.05 as a significance threshold. However, when using the following commend I get an error message:

std_plotcurve(erptimes, contrasts_5(:,1), 'plotconditions', 'together', 'plotstderr', 'on', 'figure', 'on', 'condstats', pvals, 'threshold', 0.05 )

Calculating the stats before with:
[F df pvals] = statcond(contrasts_5(:,1),'method', 'bootstrap‘);

The error message I get is:
Error using  <
Matrix dimensions must agree.

Error in plotcurve (line 104)
                           Rregions  (find(g.val2mask < g.maskarray)) = 0;

Error in std_plotcurve (line 400)
                    plotcurve( allx, tmpdata{1}, 'colors', tmpcol, 'maskarray',
                    tmpdata{2}, plotopt{3:end}, 'title', opt.titles{c,g});

If I use NaN for the threshold option it works perfectly well. Can anybody tell me what I’m doing wrong?
Best wishes
Susanne
