Hi Jia,

You can use trjconv for custom fitting, and then feed the fitted trajectory
to g_rms, not using fitting there. Either that's using -nofit or -fit none.


The same can be done in one step by using an index file with g_rms and choosing that group for fitting.

Dear gromacs users,
     I have a trajectory of 500-atom system and would like to obtain RMSD of
all atoms but only aligned to residue 1-400 of a reference structure. Is
there any way to do this?
     Thank you so much!
Regards,
Jia
