Dear Sophie,

Let's try to solve one thing at a time. First, the BATCH_12012021.mat contains the details of the batch structure that (I imagine) your Lesion*.m script is creating, but the field "filename" of that batch structure (which should point to the name of your CONN project) is also pointing to the same file "BATCH_12012021.mat". It is not a good idea to name your CONN project with the same name as another .mat file which: a) already exists; and b) happens to contain the batch that will in turn create your conn project. Could you please re-send me your Lesion*.m file? (the version that I have does not do this, so I imagine you are working with a different version?)

And regarding the memory limitations, the node that runs the conn_batch command (part of your Lesion*.m script) should not require any significant memory at all (definitely not over a few Gb), since CONN is only submitting jobs to your cluster there. If your IT team is reporting that this node exceeded the allocated memory, it must be some strange recursive-loop where Matlab is freezing while draining resources, so I would suggest to try to run the Lesion*.m file interactively and debug it (just run it one step at a time) to see where it freezes

Hope this helps
Alfonso
