* Compute forward simulated data and apply a dipole fit
They explain how to simulate two dipoles and his moments, and they set the dipole moment as:

cfg.dip.mom = [ % each row represents [qx1 qy1 qz1 qx2 qy2 qz2]
1 0 0 0 0 0 % this is how signal1 contributes to the 6 dipole components
0 0 0 1 0 0 % this is how signal2 contributes to the 6 dipole components
]'; % note, it should be transposed

My question is; if I have 128 dipoles, the structure field cfg.dip.mom should go like this:
>> for i=1:128
moms(i,3*(i-1)+1)=1;
end
>> moms=moms'; %%and then..
>> cfg.dip.mom=moms;
Because if so, I'm getting the next error:
>> dip1 = dipolefitting(cfg, avg3);
the input is timelock data with 30 channels and 250 timebins
using headmodel specified in the configuration
using electrodes specified in the configuration
selected 30 channels
selected 250 topographies
Warning: not enough channels to perform a dipole fit
> In dipolefitting at 438
??? Error using ==> dipolefitting at 471
inconsistent number of dipoles in configuration
PLEASE HELP I'LL BE VERY THANKFUL
