In case the outline of a cell was not detected, you can create it manually using the flood fill algorithm. To use it, select “Add Cell (FloodFill) (thresh X)” from the sidebar. Then, click in the middle of the cell and admire the resulting outline. The threshold (thresh) defines how much pixels might differ from the selected point to still be considered inside the outline. Its value can be changed using the mouse wheel. So if you increase this value, the area of the outline should increase. To create the new cell, confirm with the space bar. Note: this algorithm is quite CPU-intensive. There are safeguards to avoid a lockup of the program, which can be altered in the config view. Only change these values, if you absolutely know what you are doing.
