Dear Lia,

I simulated 1000 events with the pid macros given by you without any problems.
All covariance matrizes have at least one value different from zero.

Can you please have a look at the Dx, Dy, Dz values for the MVDHitsPixel / MVDHitsStrips if there are any zeros. They are the basis for the calculation of the cov matrizes.

How often does this crash happen?

Cheers,

Tobias
