Can you please provide a bit more information with respect to what version of fieldtrip, matlab and operating system you use?
Did you check whether the ‘seg’ looks healthy? Does the ‘mri’ plot well? We need more information to work with.

Hi everyone,

I have a question that is possibly very easy to solve but is evading me. I am unable to get ft_sourceplot to work. For example when I run the code:

[mri]               = ft_read_mri('MNI152_T1_0.5mm.nii');
mri.coordsys        ='MNI'

cfg                 = [];
cfg.output          = {'brain' 'scalp' 'skull'};
seg                 = ft_volumesegment(cfg, mri);
seg.anatomy         = mri.anatomy;

cfg                 = [];
cfg.funparameter    = 'brain';

I get the error:

Error using textscan
First input can not be empty. Expected a non-empty string or a valid file-id.

Error in issubfield (line 44)
t = textscan(f,'%s','delimiter','.');

Error in ft_sourceplot (line 460)
hasmsk = issubfield(functional, cfg.maskparameter);

This is happening regardless of what stage I use ft_sourceplot.

Thanks for your consideration!
