[FieldTrip] EEG sensor position layout again

[Hwee Ling Lee]

Hi,

A bit more details about my setup.

I'm using a Easycap MRI compatible 128 channels cap. I tried to search for
a layout on the templates/layout, and I found one that might closest fit to
my needs ('QuikCap_NSL_128').
To view my components, I tried these series of commands:

cfg = [];
cfg.viewmode = 'component';
cfg.continuous = 'yes';
cfg.layout = ft_prepare_layout('QuikCap_NSL_128');
ft_databrowser(cfg,ic_data);

However, I was prompted with error messages:
Warning: Struct field assignment overwrites a value with class "char". See
MATLAB R14SP2 Release Notes, Assigning Nonstructure
Variables As Structures Displays Warning, for details.
> In utilities\private\ft_preamble_provenance at 49
  In ft_preamble at 54
  In ft_prepare_layout at 91
Error using ft_prepare_layout (line 582)
no layout detected, please specify cfg.layout

Also when I tried the command,

cfg = [];
cfg.viewmode = 'component';
cfg.continuous = 'yes';
cfg.layout = 'QuikCap_NSL_128';
ft_databrowser(cfg,ic_data);

I get this error message:

cfg.style, cfg.overlap);

Error in ft_databrowser (line 226)
  cfg.layout = ft_prepare_layout(tmpcfg);


Would anyone please help?

Cheers,
Hweeling
