segmentation fault core dumped reg.
Hi @rasbt I found the Hbind tool interesting and wish to use the tool Hbind. I have used it in 2018. And now I installed the package and im getting the message "WARNING: unable to open file (null); Bad address (open_mol2) Segmentation fault (core dumped)" I tried it with the example files provided. The command which i tried is shown below. shefin@DESKTOP-S8S4EEL:/mnt/f/Hbind-master/Hbind-master$ ./bin/hbind -p ./example_files/1KPF.pdb \ -l ./example_files/1KPF_AMP.mol2
HBIND Version: 1.0.0
Documentation: http://psa-lab.github.io/Hbind Raschka, Wolf, Bemister-Buffington, Kuhn (2018) Protein Structure and Analysis Lab, MSU (http://kuhnlab.bmb.msu.edu) Please help. It is for my Ph. D work.
Thank you Shefin
I am sorry to hear that it now causes issues. The code wasn't updated since 2017, so I have no idea why it suddenly doesn't work anymore. Maybe your operating system has substantially changed and you need to recompile it?
EDIT: I do see that I changed one of the files 2 years ago (https://github.com/rasbt/Hbind/commit/e0f8beeb30672af4aff1d2612678283e49961a76). I think this was due to an issue that others got when running it. It fixed that issue back then. In your case, maybe you need the original version though.
To get the original version, you could either change that file back, or download everything from this snapshot: https://github.com/rasbt/Hbind/tree/949ca065a3fdc41df4cb350af87793e68171cc8c
Dear Mam
Very happy to say that today I executed successfully the Hbind tool as well as Hbindviz. May I know what is a doneptor? is that the atom which can act both as a donor and an acceptor.
With Kind Regards Shefin

Glad it works.

Yes, thats correct
Sir Thank you for the kind response.

Dear Sir
Can you provide more insights on doneptor. Like whether it is good to have doneptors in a protein ligand complex or what is the importance of doneptors. I couldn't find much information regarding this.\

The atoms that can act as both acceptor and donor ("doneptor") are a bit more flexible so they could potentially increase misrecognition, but they are also relatively rare. Here's a passage from our paper regarding this point:
The second most prevalent case paired a hydroxyl group donor with an oxygen acceptor (24%). Other possibilities for native ligand H-bonding were rare, particularly nitrogen atoms acting as H-bond acceptors, whether on the protein or ligand side. The tendency of hydroxyl groups to contribute only one-quarter of all protein–ligand H-bonds despite having two lone pairs and one proton, all of which can form H-bonds, can be rationalized by the resulting reduction in ligand selectivity. A ligand group with either good donor or acceptor geometry could both interact with that hydroxyl group, bringing the risk of misrecognition. This could have been the basis for negative selection during evolution.
Thank you Sir
