Table of Contents

Getting started

Requirements

  • Python 3.6
  • PyTorch 1.1.0, with NVIDIA CUDA Support
  • pip

Installation

Clone repository:

git clone https://github.com/kuixu/PrismNet.git

Install packages:

cd PrismNet
pip install -r requirements.txt
pip install -e .

Datasets

Prepare the datasets

Scripts and pipeline are in preparing, currently, we provide 172 samples data in *.tsv format for training and testing PrismNet.

# Download data
cd PrismNet/data
wget https://zhanglabnet.oss-cn-beijing.aliyuncs.com/prismnet/data/clip_data.tgz
tar zxvf clip_data.tgz

# Generate training and validation set for binary classification
cd PrismNet
tools/gdata_bin.sh

Usage

Network Architecture

prismnet

Training

To train one single protein model from scratch, run

exp/EXP_NAME/train.sh pu PrismNet TIA1_Hela clip_data

where you replace TIA1_Hela with the name of the data file you want to use, you replace EXP_NAME with a specific name of this experiment. Hyper-parameters could be tuned in exp/prismnet/train.sh. For available training options, please take a look at tools/train.py.

To monitor the training process, add option -tfboard in exp/prismnet/train.sh, and view page at http://localhost:6006 using tensorboard:

tensorboard --logdir exp/EXP_NAME/out/tfb

To train all the protein models, run

exp/EXP_NAME/train_all.sh

Evaluation

For evaluation of the models, we provide the script eval.sh. You can run it using

exp/prismnet/eval.sh TIA1_Hela clip_data

Inference

For inference data (the same format as the *.tsv file used in Datasets) using the trained models, we provide the script infer.sh. You can run it using

exp/prismnet/infer.sh TIA1_Hela /path/to/inference_file.tsv

Compute High Attention Regions

For computing high attention regions using the trained models, we provide the script har.sh. You can run it using

exp/prismnet/har.sh TIA1_Hela /path/to/inference_file.tsv

Compute Saliency

For computing saliency using the trained models, we provide the script saliency.sh. You can run it using

exp/prismnet/saliency.sh TIA1_Hela /path/to/inference_file.tsv

Plot Saliency Image

For plotting saliency image using the trained models, we provide the script saliencyimg.sh. You can run it using

exp/prismnet/saliencyimg.sh TIA1_Hela /path/to/inference_file.tsv

Motif Construction

For the construction and analysis of integrative motifs, Users can use the scripts in motif_construct/

perl saliency_motif.pl infile.txt sal outfile
Rscript motif_sig.R outfile_motif_summary.txt outfile_motif_sig.txt

Integrative motif

The integrative motif could be downloaded at here.

Half Life Analysis (Example)

Download half life data

cd PrismNet/data
wget https://zhanglabnet.oss-cn-beijing.aliyuncs.com/prismnet/data/halflife_data.tgz
tar zxvf halflife_data.tgz

Requirements

pip install xgboost==1.3.0rc1 matplotlib scipy scikit-learn termplotlib

Run Example

exp/logistic_reg/run.sh

Dataset and Results Visualization

We also provide a website http://prismnet.zhanglab.net/ to visualize the icSHAPE date and the results.
