Hi everyone,
I am new to msnoise therefore facing some issues. While trying to compute
dtt, suddenly this message starts appearing in the terminal:
"/home/zee/anaconda3/lib/python3.9/site-packages/scipy/optimize/minpack.py:833:
OptimizeWarning: Covariance of the parameters could not be estimated
warnings.warn('Covariance of the parameters could not be estimated',"
Can anyone tell me the reason behind it and how to sort out this issue.
Regards,
Faisal Umer

Hi,
It is difficult to know why you get those warnings (not errors!) when
computing dtt, it's linked to the linear regressions. Do the resulting
dtt look OK or are they full of NaN or INFs ? A reason could be that
your dtt_* parameters are set to strict and there are not enough points
for computing a linear regression. The only way to test this would be to
edit the s06compute_dtt.py file in your install & add prints/debug
information.
Regards,
Thomas
