[GRASS-user] Identify lines by starting point?

Hi

I have created flowpaths for a grid, and have to do some analysis per grid cell, i.e. per flowline.

Is there a way of identifying a line by its starting point?
I would like to provide the cell / centre of a cell and get the flowline from this point? I know I could create them separately, but this calculation is part of a simulation which is repeated several thousand times, and the grid is quite big, wherefore the individual storage of the flowlines is not an option here.

Thanks,

Rainer
