# Time series analysis BFAST Calculation not running

Asked by Dominik on 2021-02-26

Hello,

For a Masters course at my Uni (Freiburg, Germany) I would like to create some demonstrations of sepal. I just signed up for it a couple days before.
The problem, I face is, that when im trying to start the BFAST calculation of time series analysis Nothing happens... I run the c5.4xlarge instance, The dataset is the Kenya Landsat 8 test dataset.
This is a little disturbing, as I must admit im not too sure about what im doing anyway... Following the instructions of a manual I found didnt help as well.

Best,
Dominik

Now it seem sto start processing, but very quick the error: Cannot create a RasterLayer object from this file. (file does not exist) occurs.
