Dear Justin,

Thanks for your answer.

Based on your suggestion, I used following command to extend first tpr
to all steps.

gmx convert-tpr -f final.xtc -s md1.tpr -n index.ndx -o new.tpr -extend 100000

After that, RMSDs with md1.tpr and new.tpr are the same.

Please, check this link:


Note that there are no problem in the other analysis such as gmx
mindist, gmx angle anf gmx gyrate.
