Dear All,
When I am converting my CTF MEG epoched data to images, I am getting the
following warning:
Warning: Duplicate x-y data points detected: using average of the z values.
> In griddata at 107
In spm_eeg_convert2scalp at 204
My settings are:
S = [];
S.n = 32;
S.Fname = Concatenated_File_Name_Time;
S.interpolate_bad = 1;
S.modality = 'MEG';
I also have EOG channels whose chantype has been set to 'EEG' during the
conversion (this of course should not interfere since I ve selected my
modality to be 'MEG').
By browsing the Mathwoks forum, I suspect that this happens when nearby
values get very similar (as is the case with MEG data).
Anybody seen that before? Any intuitions?
Thanks and best,
Panagiotis
