Dear Loris, one way to achieve what you want is to use the modxxxfooter parameters in the eb-file (untested):
modluafooter = 'setenv("MCR_CACHE_ROOT", pathJoin("/scratch", pathJoin(os.getenv("USER"), "mcr_cache")))' modtclfooter = 'setenv("MCR_CACHE_ROOT", pathJoin("/scratch", pathJoin(os.getenv("USER"), "mcr_cache")))' Not sure if this is advisable, in particular if you use $TMPDIR as this may change from the time the module is loaded to the time Matlab is running. Wouldn't it be better to set MCR_CACHE_ROOT within Matlab based on TMPDIR?
