Dear support,
I understand i can get a faster convergence with min eigen value = 0.0001.

I have tried with tolerance 0.1 rather than 0.3 as you suggested and I performed the same excercise. I have sent you another email with screenshots.
As you can see, I get the same resuts even if I use ...

i have sent you an email on support@seismosoft.com because I need to attach figures to make myself clear.
Please carry on the discussion on emails.
thanks

Thanks for your prompt reply.
it is not just matter of time, when I set Min eigen value to 0.1 I cannot get a good spectral match.
On the other hand, by using a Min eigen value of 0.0001 I do get a very good spectral match.
could you please explain these results?
is there a way to attach figures ...

tools/program setting/matching parameters
Why is Min eigen value set to 0.1 when seismomatch is opened?
shouldn't it be better to set min eigen value to 0.0001 as suggested in the seismomatch help?

regards
