You've made it this far, with trajectories proudly in hand! Time to analyze the data.

Analysis

K-means

Below needs updating as of 6/2023

We use several different techniques in analyzing our trajectories. Some methods will be more relevant than others for certain projects, but generally you will want to begin with RMSD.

Backup
Average Hydrogen Bonds
Stacking
VMD

To convert an .rst to a .pdb (example at /mindstore/home33ext/kscopino/BIN/make_pdb_to_rst.in):
   # path to prmtop
   parm /mindstore/home33ext/kscopino/HELMHOLTZ/5JUP_GC/179_WT/TLEAP/5JUP_GC_179C_wat.prmtop

   # rst file to convert
   trajin /mindstore/home33ext/kscopino/HELMHOLTZ/5JUP_GC/179_WT/TLEAP/5JUP_GC_179C_wat.rst

   # strip solvent and ions
   autoimage
   strip :WAT
   strip :Na+
   strip :Cl-

   # write output
   trajout /mindstore/home33ext/kscopino/mR146/5JUP/COD1_C2/TLEAP/5JUP_GC_179C_nowat.pdb pdb
