For doing REMD,I have generated the five seed conformation using trjconv
command. I have taken only 10 temperature from the temperature generating
tool, now i want to know whether i have to generate different .tpr file
using one conformation at all temperature or all conformations at all
temperature. Will you please tell me what to do as i am unable to
Thanks in advance
