Error using alpha = "from.data"

[Malvina Marku]

Hi,

I am using dynGENIE3 on a 6-sample dataset, with 5 time points each. While setting alpha = fixed_value works perfectly, using alpha = "from.data" gives

Error in { :
task 2 failed - "NA/NaN/Inf in foreign function call (arg 4)"

Any idea where this error comes from, and how to solve it?
Thanks

Hi,

I would need a bit more info.

Could you run the following:
alphas <- estimate.decay.rates(TS.data, time.points),
where TS.data and time.points are the same input arguments as when calling dynGENIE3(TS.data, time.points),
and check if alphashas some nan or inf values?

Indeed, there were a few NaN values of alphas for some genes.
Thank you for your fast reply and your help.
