Author: Wayne Rasband (wsr at nih.gov) Requires: ImageJ 1.43u or later Source: Grid_.java Installation: Copy Grid_.class to the plugins folder and restart ImageJ. Description: This plugin creates a non-destructive grid of lines, crosses or points on the current image or stack. You can specify the the grid type (lines, crosses or points), the area per point (in pixels or physical units), and the color. The "Horizontal Lines" option can be used to implement the stereological method for measuring relative length of neurites in culture described in:
Ronn, L. C., Ralets, I., Hartz, B. P., Bech, M., Berezin, A., Berezin, V., Moller, A. and Bock, E. (2000). A simple procedure for quantification of neurite outgrowth based on stereological principles. J. Neurosci. Methods 100, 25-32The previous version of this plugin (renamed Grid2) is also available (Grid2_.java, Grid2_.class).
