Dear users:
I am using ptraj to calculate rmsd of one residue's sidechain by
fitting all the CAs. This is the input file:
reference ycd_rea.inpcrd
trajin md_nvt4.crd.gz
center .CA
image center
rms reference out rms-ycd-cry1-300k-mono1 :15-158.CA
rms reference out rms-ycd-rea-mono1-f114 :114.CG,CD1,CE1,CZ,CE2,CD2
nofit
The numbers I get are too small (around 0.05). The rmsd of CA is about
1.2. So I suppose the rmsd of this sidechain should be around this
number or larger.
Another problem I have is when I choose less than three atoms of the
sidechain, the program fails.
Thanks for your help in advance.
By the way, the ptraj program I have is ptraj-6.5.
Best,
Lishan
