Your output file which is saved in your working directory will contain a table of the chain-resID-resNo and their corresponding phi, psi, chi1, chi2, chi3, chi4, and chi5 values. #writes out the table to a file write.table(torsion, file = 'torsion_angles.txt', quote = F, sep = ' ') Download the script (at the Download link in the yellow box) and store it on your computer in a directory somewhere. #For example, to look at the angles for VAL, residue 223 from chain A tor$tbl This script adds several commands to PyMOL, making it easy to calculate the angles between alpha-helices and between beta-strands. #creates a table of the torsion angle torsion <- tor$tbl #identify each row by their chain, residue ID and residue Number obtained from your PDB entry res_label <- paste(pb.prot$atom$chain, pb.prot$atom$resid, pb.prot$atom$resno, sep='-')

#to get the number of rows and columns of 'tor' dim(tor$tbl) Dear PyMol Users I wounder to know about posible ways to plot for my structures different torsion angles (phy, psi, chi ) on the ramachandran map via pymol.

By default, the coordinates used are from the current state, however an alternate state identifier can be provided.

I want to select all residues that have the hydrogen bonds that I found. A step by step DIY Tutorial how to build your own Teak, Carbon, Glass fibre ,double banded, laminated wooden Speargun. This produces the contacts, but I want to show them clearly by only showing residues which have these contacts and nothing else (currently, the view is very unclear due to the rest of the protein ). If the macro begins with a slash, PyMOL expects to find the fields starting from the top of the hierarchy: the first field to the right of the slash is interpreted as an object-name the second field as an identifier to segi the third as an identifier to chain, and so on.

#calculates the torsion angles of the protein and save to dataframe 'tor' tor <- torsion.pdb(pb.prot) getangle returns the angle between three atoms. Using PyMol, I can show hydrogen bonds using Action -> Find -> Polar Contacts.

#trim to protein only pb.prot <- trim.pdb(pb, 'protein') #fetches the pdb file from the protein data bank and saves to dataframe 'pb' pb <- read.pdb('insert PDB ID') #sets the working directory to where you want. This post includes drawing anime and manga male and female head and face, from different angles too. #returns the file path of the current working directory. This post covers some of the best FREE art tutorials on how to draw anime and manga head and face.
