@barapa: i've made a change to rbmtrain to accept a cdk parameter, which specifies how many interations of the gibb markoff chain to compute. this option is part of dbn_training_params in the create_train_save scripts, where it is passed in as the new cdk parameter. it is now required so you'll have to modify your scripts. I updated src/scripts/call_train_script.m to reflect the change.
