    Thanks so much! Your tutorial is the only one that showed how to RESTART a aborted run! You're a lifesaver!

      @@trendsinwomen Unfortunately I tried restart my run like what you did in 19:50. I received "Fatal error: Error reading extended system file". How should I proceed?

      The content of the step5_production.restart file looked weird:

    Thanks a lot for the video. Your installation is in windows but in real life, using Linux and a GPU computer only give us reach biologically relevant timescales. Most of the MD community uses Linux. It will be actually useful if you can make a tutorial video on namd installation on GPU ubuntu

      Thank you so much for the comments. As per my expertise I prepared tutorial for windows setup installation to perform MD simulations. May be in future I would like to make it for ubuntu using GROMACS.

    Nicely explained! I had a query regarding the input files, can we not use only the final coordinate or velocity files for example .coor instead of restart.coor files
