Hi Paola,

Have you tried running the analysis again? If there is still an issue, could you please list your steps? The error you are seeing has never been encountered before by relax users. The "IDR_bundle" is the name of your "pipe bundle" that stores all of your data. It is created at the new analysis wizard stage. The fact that it is missing is worrying. Have you done anything between the new analysis wizard and hitting the run button which could have changed the name?

Regards,

Edward
