Why can’t we find Radius of gyration of RNA… I know it do not have alpha-helices or beta-sheets but it does have stems and loops… Why is it not possible to find Rg for it… Please help me understand it…
If you’re having a specific problem using a GROMACS tool, please be more specific and provide your actual command. You can compute Rg for any selection of any atoms; it has nothing to do with whether something is a protein or not. gmx gyrate
will calculate the value for any selection of atoms you make.
Sir actually I am working on RNA-SRV-1 and i used following command for Rg calculation:
gmx rama -f 0308_pull1_nojump.xtc -s 0308_pull1.tpr -o ramachandran1.xvg
But all i got blank graph of ramachandran
A Ramachandran plot is specifically for proteins as it is a surface of (φ,ψ) pairs. It can’t be used for RNA. You asked about radius of gyration, which is computed by gmx gyrate
. It looks like you’re simply using the wrong tool.
Ohkk… Now I got it… Thank you…
