Hello！
I have a problem when generating the time contact sheet through the epileptogenic index. I don't konw how to solve it.
Thanks！
When following the tutorial, at this step:
https://neuroimage.usc.edu/brainstorm/Tutorials/Epileptogenicity#Surface:_Seizure_2.2F3
there are two type of source maps files:
-
Files (
) EI_*, are the result of the comparison (t-test) between the mean activity at base line and the activity for the given sliding windows. So, the units for each vertex are t-values (this is also indicated in the colorbar units) . These files are time-resolved. -
Files (
) Delay_*, are summary of the epileptogenicity maps at different time points. In this plot, the value of each vertex represents the latency for which the activity in this vertex becomes significantly and continuously higher than during the baseline. As such, the units are seconds, this is also shown in the colorbar. As these maps are summaries, they are not defined in time. They consist of only one time point.
Thank you for your answer！
But when I open the time contact sheet of this file (EI_*), the same problem still appears.
If you followed the tutorial, your El_* should be time resolved in 11 time points.
Please verify this?
Right-click on one El_* file > File > View contents and check the Time field.
The contents of the file look like this, and there seems to be no problem. But generating the time contact sheet will cause an error.
If you double click the El_* file, what does in say in the right panel on Brainstorm?
What are the options you are using to create the contact sheet?
