I am running an AIMD simulation in ATK and I want to print the stress as well as the forces fx, fy and fz at each step of the AIMD run in the output log file. How to do that?

I am trying to calculate Fukui Function for periodic system using quantumATK inspired from the work J. Phys. Chem. A 2020, 124, 2826−2833 (using VASP code). As in the mentioned paper they have generated the CHGCAR file (the total charge density multiplied by the volume) for different fractional charges as well as neutral charges. Now, I want to generate the same using ATK. I have generated electron density but I am not understanding how to make this file similar as that of CHGCAR file and also I am not understanding what are the different values in electron density file represents. Another point is that how to give fractional charges during calculation.

I have prepared an input for AIMD run of 20 steps. In the output file, I want to get the following information
lattice vector, coordinates, energy and stress tensor for each step.
However, from the input that I am running, I am not getting these information. And it seems a tedious task to get the coordinates and corresponding values from the movie tool at each snapshot. So kindly tell me how to obtain these values from the AIMD run. Attached with this message is the input file that I am running.

I am trying to optimize one nanotube having 182 atoms using HSE functional with the help of LCAO calculator. Initially, I have submitted the job using m_file with two nodes (8 proc each. One node having 128 GB RAM and other node having 96 GB RAM). However, the job terminated with the following message "=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES=   PID 244987 RUNNING AT compute-0-1 =   EXIT CODE: 9 =   CLEANING UP REMAINING PROCESSES=   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES". After that we have submitted the Job using four nodes with four processor each and RAMs are 128 GB, 96 GB, 64 GB and 64 GB and this time also the job terminated with the same error. Next, I have submitted the using three nodes except compute-0-1 and this time the job stopped without showing any error. I am attaching all the log files for your reference. Kindly help me in this regard.
