processing error message

Hello,

I'm new to resting state analysis and the Conn tool. Please can you help me with the below error? I ran preprocessing on 4 subjects and checked the output it seemed fine. When I pressed 'Done' to move onto denoising it seemed to work through the steps (taking longest at importing ROIs). At the end of the process, it returned the below error. One possibility is that it is a java error?

ERROR DESCRIPTION

Undefined function 'eq' for input arguments of type 'struct'.
