Hi,
I have a question regarding the pixel/voxel sizes used in the geometry generation.
I have generated some cone beam phantoms using the code below. However, the pixel and voxel sizes do not …

Hi Mick,
There might be a small bug in `mTRFtransform.m`:
Consider the following toy example:
```matlab
% Toy dataset
fs = 8;
X = rand(8, 500) / 4 - 0.125; % eeg
y = rand(1, 500) / 4 -…
