"mexsload not found in path" Issue

[alparslanonder]

Hi, While I was trying to import my edf file (EDF-C) I faced with this problem. I removed then loaded the latest version of Biosig, try lots of things but I keep having this problem, how can I solve it?

Thanks a lot.

Do you have windows. If this is the case, then mexSLOAD should be installed. If you do not have windows then it is more complex. https://sourceforge.net/p/biosig/wiki/FAQ/

Closing this for now. I updated the help message.

Dear Arno, I have a MacOS system and followed the steps but I was not able to open an EDF file with mexSLOAD. It is of my interest because events are not loaded with the default settings.

You do not need mexsload to load EDF events. You can use other options when calling the biosig function. For example, try importing with annotation off.

EEG = pop_biosig('file.edf', 'importannot', 'off');
[ALLEEG EEG CURRENTSET] = eeg_store(ALLEEG, EEG);
eeglab redraw

Thank you so much for your answer! Still no luck while importing events after I uncheck the annotations option. After I imported the file with no events I use the "Import event info" from the menu, but more than 300k of events are imported after a long time.

When I try other import plugins like import_edf the events are imported normally but I get an error that says there is another edfread function and I need to remove it from the path.

Sorry if the question is too basic, but these are my first steps with EEGLab.

Can you share your EDF file?

Can you share your EDF file?

Absolutely Arno. It would be such an honor. I am new to EEGLab and having support from you is unbelievable.

Thank you so much. Greetings from Peru.

PS: Just to let you know that data have being acquired from a Neuron Spectrum 64. It is a russian made amplifier. We are planning to do some research with it and a same brand TMS device (TMS-EEG).

@lopezchau Ciao! Ho lo stesso identico problema... hai risolto?

[alparslanonder]

As I experienced, the exact problem was in the Headers of the .edf files, with a pipeline I solved the issue about the headers and I did not have the same issue again.

@lopezchau come hai fatto a risolvere? perchè io non riesco in alcun modo a visualizzare gli eventi nonostante io abbia la certezza che ci siano. Sono una studentessa che sta eseguendo un progetto sperimentale per la tesi e non sono riuscita ancora a risolvere
