EEGLAB error in function pop_loadbv() at line 87 #251

Closed NicoBiagi closed 3 years ago

NicoBiagi commented 3 years ago

Hi, I tried to load a .dat file using the 'From Brain Vis. Rec. .vhdr or .adhr file' option from the bv-IO1.7 plugin. I left both the 'Interval samples' and the 'Channels' blank because I was happy with the default values.

However, I get an error message saying: 'Output argument "CONF" 9and maybe others) not assigned during call to "readbvconf".

Could you please help me fix this error?

Many thanks

Dear Nico, Would you mind to share your data files?

Hi,

Thank you for your prompt reply.

I had to attach the data in .zip format because GitHub didn't let me add it as a .dat file

Best, Nico Example_data.dat.zip

arnodelorme commented 3 years ago

Thank you. We would need the associated .vhdr and the .vmrk files as well to be able to run some tests.

NicoBiagi commented 3 years ago

I don't have the .vhdr file, just the .vmrk file Example_data.vmrk.zip

arnodelorme commented 3 years ago

If you do not have these files, then the data cannot be imported. The files always come in 3 (a .dat, a .vhdr, and a .vmrk file). Best

arnodelorme commented 3 years ago

The .vhdr is the header file and it is the most important. the .vmrk is the marker file (events) and it is optional.

NicoBiagi commented 3 years ago

here is the .vhdr file relative to the example dataset I've sent you Example_data.vhdr.zip

arnodelorme commented 3 years ago

It is not a good idea to rename files because they refer to each other. When the files are named properly, they can be imported.
