Import ROI step : problem with rex.m function

Hi everybody,

I am running the "setup" step by using a batch (conn_batch function) on rs-fMRI data of one subject. I put all the ROIs that I want CONN extracts the signal in the folder .../rois/ and when I run my batch on my PC (which have 2017 version of Matlab and the last version of conn), everything works. However, when I run my batch by using a remote cluster (which uses 2013 version of Matlab and the last version of conn), it fails during the 5/7 step, when conn tries to import the rois.
Here is the message of error :

Somebody could give me some clarifications/explanations?
Many thanks
