Introduction

We propose a two-level general-purpose protein structure embedding neural network, called ContactLib-ATT. On local embedding level, a biologically more meaningful contact context is introduced. On global embedding level, attention-based encoder layers are employed for better global representation learning. Thus, ContactLib-ATT is used to simulate a structure-based search engine for remote homologous proteins.

Usage

The input of this search engine should be protein structure format, such as *.ent and *.pdb. The trained model can be downloaded from Zenodo.

Run

Clone this repository by:

git clone https://github.com/xfcui/contactlib.git

Make sure the python version you use is >= 3.7, and install the packages by:

pip install -r requirements.txt

Optional arguments:

-h, --help                show this help message and exit
--file FILE               the input file (relative path)
--gpu GPU                 assign the gpu num

Run:

python run_contactlib.py --file contactlib/data/d3c92k1.ent --gpu 0

contactlib's Issues

how can i get each pro's json file

How can I get each pro's json files. I noticed the code 'run_contactlib.py' use the json file but not the ent file. How to transfer an ent file to a json file.
