The following steps are required in order to run AMPs-Net:

$ export PATH=/usr/local/cuda-11.0/bin:$PATH 
$ export LD_LIBRARY_PATH=/usr/local/cuda-11.0/lib64:$LD_LIBRARY_PATH 

$ conda create --name amps_env 
$ conda activate amps_env 

$ bash amps_env.sh

We provide pretrained models available for download in the following link. Last update on the models on the 01/01/2023.

To train each of the components of our method: please refer to run_AMP.sh and run_multilabel.sh.

To perform inference on your data please refer to: run_inference_AMP.sh and run_inference_multilabel.sh.

To setup your data on the proper format for our models please refer to generate_metadata.sh. Your dataset should be a csv file with a column name Sequence and your peptides in their AA sequence. Follow the example in data/datasets/Inference.

To perform inference with your models please modify L34-37 from inference.py. (Change Checkpoint.pth to Checkpoint__valid_best.pth)
