My folder 'dataset' contains Events.Nev file and *.Ncs files. Even following tutuorial guidelines I can not get this read. Although read_header should be able to read e.g. 'nev' in general I see no reference to this in the code. Here is my error hdr=ft_read_header('dataset'); ??? Error using ==> plus Invalid type of input arguments (should be uint64) Error in ==> read_neuralynx_ds at 133 LastTimeStamp(i) = LastTimeStamp(i) + uint64((recordsize-1)*TimeStampPerSample(i)); % this should be in uint64 precision Error in ==> ft_read_header at 850 hdr = read_neuralynx_ds(filename);
