MATSim Zurich Tutorial shuts down suddenly at the 10th iteration. It produces no event file or graphs at the 10th iteration

Hi can anybody pls help me, i am new to MATSim and i have been trying for days to figure out why my simulation of the MATSim Zurich tutorial gives me the below error at the 10th iteration. I really need help with this, as i am working with a strict deadline.

Hi,

unfortunately, it is not quite clear to me, which MATSim tutorial or version you are referring to.

For a smooth "Getting started" tutorial, I strongly recommend to use the latest MATSim version with the latest tutorial:

Best regards,

Joschka

It seems like at the 10th iteration the simulation tries to compare the result with the count data (the validation data i.e. counts.xml). That's when the error is produces at org.matsim.counts.algorithms.CountsComparisonAlgorithm.setDistanceFilter(CountsComparisonAlgorithm.java:163). Still trying to resolve this.
