Description of the variables in file exvivo_RFs.mat
spatial_all - 101 x 101 x 31135, spatial RF snapshots, at 10um/pixel resolution
temporal_all - 31135 x 65, temporal RFs of the center, at 25ms/sample resolution
centroids - 31135 x 2, location of each neuron on the retina. Temporal (-ve dim1), Nasal (+ve dim1), Dorsal(-ve dim2), Ventral(+ve dim2). (0,0) is the optic nerve head
polar_coords - 31135 x 2, dim1 - lambda (longitude) and dim2 - phi (latitude), location of neurons in polar retinal coordinates, following Retistruct conventions. NaN if unavailable.
gprops_all - 31135 x 1 structs, difference of gaussian parameters. Note that these were fit on the whole spatiotemporal RF before transformation to common coordinates.
scRatio - 31135 x 1, relative surround strength of each neuron
centSize - 31135 x 1, size of the center mask
rfAsymm - 31135 x 1, vertical surround asymmetry
group_idx - 31135 x 1, assigned clustering groups for each neuron
ret_number - 31135 x 1, retina id from which each neuron was recorded
sopsin_gt - 31135 x 1, whether this neuron comes from a retina with ground truth orientations
isright - 11 x 1, 0 if it is a left retina, 1, if it is a right retina
sopsin_dorsal - 11 x 1, angle (in degrees) of the dorsal direction of each retina, with respect to the horizontal, as estimated form the s-opsin staining. NaN if unavailable.
manual_dorsal - 11 x 1, angle (in degrees) of the dorsal direction of each retina, with respect to the horizontal, as estimated form location of the asymmetric streak. NaN if ground truth sopsin orientation was available.
idxs - 1 x 3 lists, indices of example neurons from ventral, central dorsal and peripheral dorsal region of one retina
chirp_response - 31135 x 300, median chirp responses, normalized, at 100ms/sample resolution, NaNs if unavailable
chirp_qi - 31135 x 1, quality index of chirp responses, NaNs if unavailable
