Time window in time-frequency calculation & Display on cortex

Hello,

My software environment is: Brainstorm 22-Mar-2019, MATLAB Version: 2014b.

I have two problems when running “SEEG epileptogenicity maps”. I’m not sure whether my operation is right. So I need your help.

The first problem is that I cannot adjust the time window when I do the time-frequency z-score calculation. I follow the ‘Help-Guidelines-epileptogenicity maps’ steps and set the time window around seizure onset to [-10s +20s]. But in the time-frequency figure, it seems that the default limit is nearly [-9.5s +9.4s]. What should I do if I want to choose a longer window?


The second problem is that after I calculate the time-frequency z-score, choose ‘display on cortex’ and right click the figure to choose ‘Channels-SEEG contacts’, it shows an error message as below when I set the time-base to another time point.



Looking forward to your apply.

The panel "Guidelines > Epileptogenicity" has many analysis parameters hard-coded, including the duration of the time window for the time-frequency analysis.
If you want to compute the time-frequency decomposition of the "onset" file, drop the file in the Process1 box and run the time-frenquency analysis manually (multitaper or Morlet wavelets):

The second problem is that after I calculate the time-frequency z-score, choose ‘display on cortex’ and right click the figure to choose ‘Channels-SEEG contacts’, it shows an error message as below when I set the time-base to another time point.

Update Brainstorm to get the fix.
Thanks for reporting.
