Residue descriptors identify selected residues

°	Residue descriptors identify selected residues

Residue descriptors are instances of the class res_descriptor. Typically, you loop over all residue descriptors in the ith selection menu:


for j in range(yasara.selection[i].residues):
  residue=yasara.selection[i].residue[j]

And then access various residue properties:


residue.name3	The name of the residue in three letter code.
residue.name1	The name of the residue in one letter code.
residue.number.inyas	The unique number/ID of the residue in YASARA (a string).
residue.number.inall	The sequential number of the residue in the soup (a string, starting with 1).
residue.number.inobj	The sequential number of the residue in the object (a string, starting with 1).
residue.number.inmol	The sequential number of the residue in the molecule (a string, starting with 1).
residue.number.inpdb	The number of the residue in the PDB file (a string, last character may be the insertion code).
residue.object	The object descriptor for the object the residue belongs to.
residue.molecule	The molecule descriptor for the molecule the residue belongs to.

You could then color the residue yellow:


  yasara.ColorRes(residue.number.inyas+",Yellow")

Or display a ribbon for the entire molecule containing this residue:


  yasara.ShowSecMol(residue.molecule.number.inyas,"Ribbon")

If you wonder why a '+' is used to combine the arguments in the first case, while a comma ',' is used in the second case, look here .
