Detecting Custom Events

[saeed]

Hello dear Brainsormers,

I have a problem with ruuning the "Custom event detection" on the recordings. I use the following settings:

When I run it I get this error message:

I wonder if it is in connection with the other error message that I asked about here (for visualizing dipoles):

Plotting selected dipoles

Hello, I have been trying to create a struct of dipoles with a goodness of fit above 50. I export to MATLAB the dipoles in brainstorm and run my code on it and then, when I import the struct in brainstorm and double click on it to display it, I get the following error: [image] This does not happen when I filter the dipoles using other values for goodness of fit. Do you have any idea about what I am missing here? P.S: 10 dipoles remain after filtering for GOF>50%. Thank you, Saeed

I appreciate your comments,
Saeed

Hi Saeed,

After starting Brainstorm, could you run the line below and report the result?
which fir1

The reported error seems to be caused by fir1 function different from the one in the Signal Processing Toolbox - MATLAB

Best,

Hello Raymundo,
After starting Brainstorm and running the line, this is the result:

\192.168.0.101\raid_02\Saeed\fieldtrip-master\fieldtrip-master\external\signal\fir1.m

Best,
Saeed

UPDATE: According to what Raymundo said, I just removed all the "set path" folders that pointed to fieldtrip (\192.168.0.101\raid_02\Saeed\fieldtrip-master) and "detect custom events" is working fine again.

I guess when I installed the fieldtrip plugin on Brainstorm, it did the "set path" which caused this error. Is it probably a bug?

Thank you Raymundo,
Saeed

I guess when I installed the fieldtrip plugin on Brainstorm, it did the "set path" which caused this error.

Your FieldTrip path (\192.168.0.101\raid_02\Saeed\fieldtrip-master), suggests that FieldTrip was manually added to the Matlab path, rather than by a Brainstorm plugin, as the path of plugins is $HOME/.brainstorm/plugins/ . More details in the Plugins tutorial

@saeed

Is it probably a bug?

Not really. It has to be with how the path is handled by the user. If FieldTrip is added as a Brainstorm plugin, FieldTrip's path is added at the end, thus which fir1 returns the function from the Signal Processing Toolbox (MATLABROOT/toolbox/signal/signal/fir1.m) which is the required by bst_bandpass_hfilter.m at L183
