Greetings,

I am working on MD simulations, specifically on CPPs and cell-membrane interaction. Can anyone please guide me on how I can extract the CA-atoms and P-atoms (Phosphorus atoms of the upper layer of membrane) information (index.ind file) from my large DCD file? Apart from this, how to use a catdcd command for splitting a large dcd into smaller ones, and how to read a DCD file in MATLAB using Matdcd plugging? Thank in advance Best regards, Muhammad Raza
