Description
Correct z-component of a 3D collagen invasion essay.
The correction is achieved under the assumption that non-migrating cells of the essay approximately
form a quadratic flow profile due to frictional effects, compare law of Hagen-Poiseuille for flow in a tube.
Usage
1
2
correctByConicalPlane(filename, nrfits = 1000, threshold = -30,
plot = FALSE, write_csv = TRUE)
Arguments
filename
Name of data file in csv format. It should contain columns "Pos_X", "Pos_Y" and "Pos_Z".
nrfits
Numeric, Number of randomly chosen starting points for the optimization. Choose lower values for speeding up computational time.
Choose higher values for more reliable optimization results.
threshold
Numeric, A threshold for counting cells as being invaded or not. When cells move towards negative z-direction, threshold should be negative.
plot
Boole, if TRUE exemplary 3D plots before and after the correction are plotted
write_csv,
if TRUE resulting corrected values are saved as a csv file
Value
Data.frame containing input positions, corrected z-positions as well as number and percentage of invaded cells.
