Hi Tommaso

It seems that you forgot to comment the &END of the commented &THERMOSTAT section above the &ENERGY section which prematurely ends your &MD section.

Best regards

Dear all,
I'd like to ask help for properly setting the annealing calculation of my molecular crystal. The ultimate goal would be description of the cell dynamic from a high temperature monoclinic phase to low temperature triclinic one. I would like to test both heating and cooling procedures, with the intent to identify the collective variables to later use in a metadynamic calculation.

So, as I set the input (heating mode) following the few examples reported, the calculation crashes saying that in the &PRINT section the &ENERGY block is not recognized. Can you kindly help me fix the problem or tell me I should avoid to put in the input file?

Here the input:
