VHDR reader / BrainVision reader crashes the Designer
Posted: Thu Mar 03, 2022 11:34 am
Hi,
so I want to read a recording in the format .vhdr into OpenVibe, which should be supported (according to http://openvibe.inria.fr/supported-file-formats/).
I was not exactly sure which reader is the correct one, since there is neither a VHDR- nor a BrainAmp-reader box to find in the Designer (nor did I find anything online). But the description next to the 'BrainVision format file reader' says 'Reads input havin BrainAmp file format', which seems to be the right one. If I now try to read the file there are two main problems: first there is the setting 'Epoch size', which surprised me a bit, since my file is not epoched but raw, so I went with the default (since there is no documentation about that setting at all). And second, as soon as I start the Designer it crashes and closes, no Error message, only a warning ('[WARNING] {[Common infos]} looked like a new section in the header file but is not know of this parser. Therefore anything after this line will be skipped until a new section is found').
I am not exactly sure what I did wrong. Maybe I misunderstood the 'Epoch Size' setting, or I have to use a different reader.
The VHDR file can be read by python, using MNE, without any problems.
Maybe someone of you has any idea what went wrong.
System:
Windows 10
OpenViBE 3.2.0
Thanks in advance,
Best Wishes
Fabian
