[Eeglablist] bva io plugin scaling

[basile pinsard]

Hi all,
The bva-io plugin had a bug which prevent correct scaling of the data.
most of the operation on chanlocs was not stored in EEG structure
I mainly changed the lines  117-136 of pop_loadbv.m for the following to
restore correct scaling.


if isfield(hdr, 'channelinfos')
    for chan = 1:length(chans)
        try
            [EEG.chanlocs(chan).labels, EEG.chanlocs(chan).ref,
EEG.chanlocs(chan).scale, EEG.chanlocs(chan).unit] =
strread(hdr.channelinfos{chans(chan)}, '%s%s%s%s', 1, 'delimiter', ',');
        catch % Octave compatible code below
            str  = hdr.channelinfos{chans(chan)};
            [EEG.chanlocs(chan).labels str] = strtok(str, ',');
            [EEG.chanlocs(chan).ref        str] = strtok(str, ',');
            [EEG.chanlocs(chan).scale      str] = strtok(str, ',');
            [EEG.chanlocs(chan).unit       str] = strtok(str, ',');
        end;
        EEG.chanlocs(chan).labels = char(EEG.chanlocs(chan).labels);
        EEG.chanlocs(chan).scale =
str2double(char(EEG.chanlocs(chan).scale));
%             EEG.chanlocs(chan).unit =
native2unicode(double(char(EEG.chanlocs(chan).scale)), 'UTF-8');
%             EEG.chanlocs(chan).datachan = chans(chan);
    end
    if isempty([EEG.chanlocs.scale])
        EEG.chanlocs = rmfield(EEG.chanlocs, 'scale');
    end
end;



I am kind of lost between the repository for the code though so I didn't
pushed anything.

Cheers.
