SFig2a: 5 animals (rows) by 15 days (1 to 15 left to right)
SFig2b: 520 1ms time bins (rows)  by 50 trials per grating directions (sheets)
SFig2c-1: 24 row blocks (neurons) and 15 column blocks (days) , with blocks separated by one line of 0, each block is  of size 5x6 which are 5 spatial frequenies and 6 orientations in same order as in Fig1f
SFig2c-2: each sheet is 6 neurons (rows) by 16 sequential grating directions per day. 
SFig2d: 30 row blocks (neurons) and 15 column blocks (days) , with blocks separated by one line of 0, each block is  of size 9x9 which are vertical and horizontal locations in the  same order as in SFig2d
