Uncaught exception error

[sgu0752]

Hi xiangjun,

I use v1.9.4-2019jul08 of 3DNA-DSSR to analyze PDB structures, and I encountered an error looking at a relatively recent NMR structure 6jwe.

Code: [Select]

x3dna-dssr --more --loop=with-stems --json -i=6jwe.pdb -o=6jwe.json
Processing file ‘6jwe.pdb’
  total number of nucleotides: 20
  total number of base pairs: 18
Uncaught exception ‘Assertion failed’ raised at [fncs_hbond.c:826]
aborting...
Thanks in advance!

Hi,

The DSSR version you used is v1.9.4-2019jul08. The latest DSSR version is v2.3.2-2021jun29, which works as expected for PDB entry 6jwe, as shown below:

Code: [Select]

x3dna-dssr --more --loop=with-stems --json -i=6jwe.pdb -o=6jwe.json

Processing file '6jwe.pdb'
    total number of nucleotides: 20
    total number of base pairs: 18
    total number of helices: 2
    total number of multiplets: 4
    total number of atom-base capping interactions: 2
    total number of splayed-apart dinucleotides: 2
    total number of non-loop single-stranded segments: 1
    total number of G-tetrads: 3
    total number of G4-helices: 1
    total number of G4-stems: 1
So please update your DSSR to the latest version (available exclusively from Columbia Technology Ventures).

Best regards,

Xiang-Jun
