flexpepdock_score_only

[Anonymous]

Hi,
I used flexpepdock_score_only find the rmsca between 2 complexes. I also caculated the rmsca between the 2 complexes ((deltax^2+deltay^2+deltaz^2)^0.5) but the rmsCA score I got was different than the one I got using flexpepdock_score_only. Why is that happening?

Note – both complexes have the same sequence of aa.

Thanks!

How exactly did you get the rmsds in the two cases, and how far off are they?

If I read things correctly, the rmsdCA that’s being put out by FlexPepDock is the rmsd for the Calpha atoms of the peptide only, without any sort of superposition. If you calculate the rmsd of the whole complex, or try to do a superposition of the peptide (or the whole complex) first, you’ll likely not get equivalent values.

thanks!
It turns out my problem was an incorrect formula and calculating rmsd on the entire complex
