I am working on a school project related to the Biomag 2012 analysis competition.
I have downloaded a .zip file from ftp://ftp.fcdonders.nl/pub/biomag2012/.
I have extracted the content and I am interested in the second objective,
the one related to long-term memory representations (folder data2).
I was able to load the 2 mat files into Matlab workspace.
I was also able to use FieldTrip functions on tutorial code.
However, when I try to use ft_preprocessing on one of the mat files I get an error.
Here is the code I wrote:
cfg1.dataset = 'ltmcla_S08.mat'
data_org = ft_preprocessing(cfg1)
And the error is:
??? Error using ==> ft_read_header at 1639
unsupported header format (matlab)
Error in ==> ft_preprocessing at 344
hdr = ft_read_header(cfg.headerfile, 'headerformat', cfg.headerformat);
I saw a tutorial using ft_read_header, ft_read_data and ft_write_data
on a .dat file that was converting it to a mat/bin pair.
However, I do not have a .dat file, I have a .mat file.
Just in case is necessary, I write some details of the .mat file:
Is a 1*1 matlab structure with the following fields:
data, channel, design, time, fs, dim.
How could I use FieldTrip on this data? If there are more ways, which one would be the fastest/easiest?
Thanks a lot,
