What you are asking for is already available in DSSR (and 3DNA). See the auxiliary file, named dssr-torsions.txt by default, from a DSSR run. For example, with 1ehz:
x3dna-dssr -i=1ehz.pdb -o=1ehz.out # check dssr-torsions.txt
# Alternatively, with the --prefix option
x3dna-dssr -i=1ehz.pdb -o=1ehz.out --prefix # check 1ehz-torsions.txt
The content of the dssr-torsions.txt file is as below:

Main chain conformational parameters:
alpha: O3'(i-1)-P-O5'-C5'
beta: P-O5'-C5'-C4'
gamma: O5'-C5'-C4'-C3'
delta: C5'-C4'-C3'-O3'
epsilon: C4'-C3'-O3'-P(i+1)
zeta: C3'-O3'-P(i+1)-O5'(i+1)
e-z: epsilon-zeta (BI/BII backbone classification)
chi for pyrimidines(Y): O4'-C1'-N1-C2; purines(R): O4'-C1'-N9-C4
Range [170, -50(310)] is assigned to anti, and [50, 90] to syn
phase-angle: the phase angle of pseudorotation and puckering
sugar-type: ~C2'-endo for C2'-endo like conformation, or
~C3'-endo for C3'-endo like conformation
Note the ONE column offset (for easy visual distinction)
ssZp: single-stranded Zp, defined as the z-coordinate of the 3' phosphorus atom
(P) expressed in the standard reference frame of the 5' base; the value is
POSITIVE when P lies on the +z-axis side (base in anti conformation);
NEGATIVE if P is on the -z-axis side (base in syn conformation)
Dp: perpendicular distance of the 3' P atom to the glycosidic bond

Assignment of sugar-phosphate backbone suites
bin: name of the 12 bins based on [delta(i-1), delta, gamma], where
delta(i-1) and delta can be either 3 (for C3'-endo sugar) or 2
(for C2'-endo) and gamma can be p/t/m (for gauche+/trans/gauche-
conformations, respectively) (2x2x3=12 combinations: 33p, 33t,
... 22m); 'inc' refers to incomplete cases (i.e., with missing
torsions), and 'trig' to triages (i.e., with torsion angle
outliers)
cluster: 2-char suite name, for one of 53 reported clusters (46
certain and 7 wannabes), '__' for incomplete cases, and
'!!' for outliers
suiteness: measure of conformer-match quality (low to high in range 0 to 1)
[Ref: Richardson et al. (2008): "RNA backbone: consensus all-angle
conformers and modular string nomenclature (an RNA Ontology
Consortium contribution)." RNA, 14(3):465-481]
