[Qgis-user] Distance matrix using shortest path

[Clemens Raffler]

Hi,

can you send me the error message that informs you about the limit? I 
was just wondering because I did not add any restriction on the number 
of input points in QNEAT3, neither in the n:n, nor in the m:n 
algorithms. I have also performed analyses with more than 5000 points 
per dataset (of course this analyses take much more time because of the 
higher workload).

Best,
Clemens
