[FieldTrip] Potential bug using ft_dipolefitting with fieldtrip-20200623

[Martin Schaefer]

Dear all,

I ran into the following error message when calling the ft_dipolefitting function on my data:

Error using reshape
Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension.

Error in ft_dipolefitting (line 444)
      dip.pos = reshape(dip.pos,3,cfg.numdipoles)';     % convert to a Nx3 array

Error in dipole_fitting (line 152)
dipole_eeg_late = ft_dipolefitting(cfg, timelockeds{4});

My cfg commands:
cfg = [];
cfg.gridsearch         = 'yes';
cfg.numdipoles      = 1;
cfg.symmetry         = [];
cfg.grid                    = leadfield_eeg;
cfg.headmodel      = headmodel_eeg;
cfg.dipfit.metric    = 'rv';
cfg.model               = 'regional';
cfg.senstype          = 'eeg';
cfg.channel           = 'all';
cfg.nonlinear        = 'yes';
cfg.latency             = early_latency;
cfg.backproject     = 'yes';

dipole_eeg_early = ft_dipolefitting(cfg, timelockeds{4});


However, the code runs fine on an older version of fieldtrip (the one used during the last online fieldtrip workshop, I think it is from 16-04-2020).

So I'm not sure whether there is a bug in one of the versions or something else is wrong.
Does anyone else have issues with this?

Best regards,
Martin
