Hi there, I'm trying to do a time-frequency analysis using morlet wavelet option and it keeps generating error messages. The same dataset was used in a time-frequency analysis a month ago and everything was fine then. I'm not sure if the error was due to mistakes on my part or is it a bug, but I attached a screenshot here.
I have run some tests here and everything seems to be working fine.
Which are Morlet wavelet options you're using for the analysis?
I used the Frequency ->Time-Frequency(Morlet wavelets). I apply this step to a minimum-norm source data, and the error appeared.
I meant the parameters that are shown when you click the [Edit...] button in Process options.
Sorry I misunderstood earlier, it is like this.
What's your version of Brainstorm?
Does the error occur for every file?
Yes, it occurs to all my source files.
And my version is brainstorm_210202, I believe it's Brainstorm 3, but not sure.
Can you update Brainstorm to the most recent version (17-Jul-2021)?
The problem persists after update to the latest version.
Can you generate simulated signals, and do the TF analysis?
- With no files in Process1, click on Run, then Simulate > Simulate generic signals, and these parameters.
yes, I can simulate the signals. But I still cannot run TF morlet wavelet, although if I change the frequency definition parameter to Log, it can generate result, but not the linear function.
It's a typo in the Morlet wavelet options, the second colon (
:) is missing
It should say
That must be it! Thank you so much for your help!
