Execute nodes not active

Hi everyone!

I’m pretty new to Knime and I’ve just started using it.

I’ve run the workflow (part with training and then part with a new sample to test if it will succeed). But now, the icons Execute selected node and Execute all executable nodes are disabled / greyed out.

Do you know why I cannot rerun the workflows?

Thank you!

Hi there @marthannea,

welcome to KNIME Community!

If you executed entire workflow these options will be grayed out. When you reset some node then you will have these options available again and you can rerun workflow. If I got it wrong maybe you can post some screenshot of what is troubling you.
