Hello!!!!
Please Help out. where am I going wrong?
cfg = [];
cfg.channel = 'EEG';
cfg.method = 'sam';
cfg.grid = grid;
cfg.vol = vol1;
cfg.projectnoise = 'yes';
cfg.keepfilter = 'yes';
source = ft_sourceanalysis( cfg, timelock);
workspace of grid,vol1,timelock (.mat)

1. Using fieldtrip 2013 version
When i do EEG sourceanalysis using "SAM" method, following error occurs
Attempted to access noise(0); index must be a positive integer or logical.
Error in ==> beamformer_sam at 111
noise = noise(end);
Error in ==> ft_sourceanalysis at 841
dip(i) = beamformer_sam(grid, sens, vol,
squeeze_avg,squeeze(Cy(i,:,:)), optarg{:});
PS: same code for MEG source reconsturction works quite good.
2. Using fieldtrip 2014 version
when i do the same I'm getting this kind of errors
Undefined function or variable 'abort'.
Error in ==> ft_sourceanalysis at 156
if abort
PS: Moreover, I cant even do preprocessing with 2014 fieldtrip version. It
is showing same above error.
advance thanks for your kind help.
