❌eddy failed to start. Either eddy is missing, or you have no permission to run it.

Hi Frank,

Whenever I try to perform an Eddy correction to my files with recent DSI Studio version, it gives this error "❌eddy failed to start. Either eddy is missing, or you have no permission to run it.", while for old version (for example, Oct2024) it works without any problem.

My FSL version is 6.0.7.12.

I'm using an Ubuntu2204 computer.

How can I fix this?

Thank you for your response.

Best regards

GR

I updated DSI Studio to fix this bug and should be ready in one hour.

If still doesn't work, please let me know.

Best regards,

Frank
