I can’t quite identify from the source code off grating.py, the default size of the grating stim? It seems to be set to a default size of [1.0, 1.0] with the units=’’ (I assume it is set to norm?). I wish to specify the size of the grating stimulus in pixels. But when I did this, the spatial frequency turns wonky in such that it made the gabor stimulus move in ‘3D’. The source code mentioned that ‘sf’ depends on whether unit is set to deg, cm or norm, but nothing on pix.
Any help would be appreciated!
