Source Codes for Human SCS Analysis

You can use the Python code easily with your computer or the Google Colab & Google Drive.

How to use the Human SCS Analysis Program with your computer

1. Download the source code and Protein Datasets

• and then locate Human_SCS_Analysis.py in the current directory and Protein data as ./ncbi_dataset/protein.faa

2. Run jupyter notebook at your current directory
3. Start to use the program by importing Human_SCS_Analysis

    import  Human_SCS_Analysis as hscs  
    hscs.initializeFromProteinDataset() 
    # You can set all data to use the application   
    hscs.menu()
    # You can see the command list
    # For example, to show the basic information of the dataset
    hscs.showBasicInformation()

How to use Human SCS Analysis Program with Google Colab

1. Download the source code and Protein Datasets

• locate Human_SCS_Analysis.py at the Google Drive directory and Protein datasets at ./ncbi_dataset/protein.faa

2. Open a new notebook in the Google Colab and mount the Google Drive directory
3. Start to use the application by importing Human_SCS_Analysis

    import  Human_SCS_Analysis as hscs   
    hscs.initializeFromProteinDataset()
    # You can set all data to use the application   
    hscs.menu()
    # You can see the command list
    # For example, to show the basic information of the dataset
    hscs.showBasicInformation()

Source Codes for SARS-CoV-2 SCS Analysis

0. Setup an environment on your computer to compile c++ source codes. Commandline tools are required. For linux and MacOS, the standard terminal tool is enough. For Windows 10 users, we recommend installing WSL or WSL2.
1. Download SARS-CoV-2_SCS_Application and Protein Datasets to a working directory.
2. Run make command at the working directory to build the software:

    yourPC:~$ make

3. Instead of the make command, you can compile the source codes directly to bilud the software:

    yourPC:~$ g++ -std=c++17 -stdlib=libc++ -o covid-scs-analysis main.cpp calculation.cpp transform.cpp

4. You can run the application software with input data located at the directory ./ncbi_dataset by the following command:

    yourPC:~$ ./covid-scs-analysis

5. The output files are generated under the output directory ./SARS-CoV-2_SCS_Analysis as csv files.

Additional Data

We provide the following additional data as Excel files: Additional Data:

1. Self-nonself assignment and Nonself extraction,
2. Nonself clusters,
3. SARS-CoV-2 variant proteomes,
4. Spike mutations
