How can I use AnyWave for reviewing continuous data?
AnyWave is a free, multi-platform software that can be used to visualize electrophysiological data, as well as being used as a development framework in order to build custom plug-ins. It is implemented in C++ and available for Windows, Linux and macOS. The graphics of AnyWave is much faster than ft_databrowser or MATLAB figure sin general, which is especially valuable if you have many channels and/or a very high sampling rate.
You can export data that has been processing in FieldTrip to a format that AnyWave understands, such as the BrainVision .vhdr format, review the data in AnyWave, and import the marked time windows back into MATLAB.
% start with the normal preprocessing of your data cfg = ... data = ft_preprocessing(cfg); dat = ft_fetch_data(data); hdr = ft_fetch_header(data); filename = 'exportfile.vhdr'; ft_write_data(filename, dat, 'header', hdr);
After writing the data to disk, you open AnyWave, read the data and mark the time windows of interest. You can export the markers to a .mrk file and read that back into MATLAB.
