The data is split into separate folders for each figure.

Figure 1

Contains the raw SEM images used

Figure 2

Has one excel file with the Mean and StdDev of each well imaged. ImageJ was used to obtain the data from the images. The raw images can be found in the two folders called Gradient Test Chip 1/2. These folders contain .tif stacks of the 8 well positions which can be read using ImageJ.
