        **TIDE** (**T**umor **I**mmune **D**ysfunction and **E**xclusion)  is a computational framework developed to evaluate the potential of tumor immune escape from the gene expression profiles of cancer samples. This package provides a python implemented CLI, and python module with Pandas inputs and outputs. If you prefer to run TIDE online, please use `Response Prediction` module on our website : http://tide.dfci.harvard.edu/. 
        
        
        ## System requirements
        - Linux/Unix
        - Python (>=3.4)
        
        ## Installation
        - Clone from github
        ```sehll
        $ git clone git@github.com:jingxinfu/TIDEpy.git
        $ cd TIDEpy
        $ pip install .
        ```
        - From the [pypi](https://pypi.org/project/tidepy/), a python package management tool
        ```
        $ pip install tidepy
        ```
        
        
        
        ## What is the input data format?
        
        The input data should be a square matrix of gene expression profiles for all patients. Each column represents the patient ID, and each row represents a gene name which can be either symbol name (e.g., TGFB1) or Entrez ID (e.g., 7040). Please see some samples from [anti-PD1](http://tide.dfci.harvard.edu/download/GSE78220.self_subtract.gz) or [anti-CTLA4](http://tide.dfci.harvard.edu/download/VanAllen.self_subtract.gz) therapies in melanoma. 
        
        #### In detail:
        
        **Expression File**
        
        1. If it's possible, please input a normalized expression file follows the instruction:
        
           - The gene expression value should be normalized toward a control sample which could be either normal tissues related with a cancer type or mixture sample from diverse tumor samples. The log2(RPKM+1) values from a RNA-seq experiment may not be meaningful unless a good reference control is available to adjust the batch effect and cancer type difference. In our study, we used the all sample average in each study as the normalization control.
             
           - Otherwise, We'll do the normalization for you by:
                 
                1. Do the log2(x+1) transformation
                2. Subtract the average across your samples.
        
        2. If it's possible, please convert your gene identifier into Entrez ID based on your annotation GTF files. 
              Otherwise, we will use our annotation GTF to do the conversion, which is gencode v27.
        
        **Cancer Type:**
        
         We validated TIDE performance on predicting anti-PD1 and anti-CTLA4 response across several melanoma datasets and a limited dataset  of non-small cell lung cancer (NSCLC). TIDE may not work on cancer types other than melanoma and NSCLC (e.g., glioblastoma, or renal cell carcinoma) and therapies other than anti-PD1 and anti-CTLA4 (e.g., anti-PDL1, or Car T). 
        
        ## Usage
        
        ### Run TIDE through command line:
        
        ```
        usage: tidepy [-h] -o OUTPUT -c {Melanoma,NSCLC,Other} [--pretreat]
                    [--vthres VTHRES]
                    expression
        
        positional arguments:
          expression            Path to expression profile.
          											
        
        optional arguments:
          -h, --help            show this help message and exit
          -o OUTPUT, --output OUTPUT
                                Output Path (default: None)
          -c {Melanoma,NSCLC,Other}, --cancer {Melanoma,NSCLC,Other}
                                Cancer Type (default: None)
          --pretreat            A previous immunotherapy (e.g., progressed after anti-
                                CTLA4 before current anti-PD1) will change the
                                response prediction rule. Please put the flag with
                                previous line of immunotherapy. However, earlier
                                treatments of targeted therapies or chemotherapies
                                should not be considered here, and please do not put
                                the flag. (default: False)
          --vthres VTHRES       Threshold to distinguish responder fron non-responder
                                based on TIDE value. (default: 0.0)
        ```
        
        #### Example
        
        Please download the first example file under **Response Prediction** module on our website: http://tide.dfci.harvard.edu. The file name should be `GSE78220.self_subtract.zip`. To obtain the immune-related metrics for this study, you can run following code on your terminal:
        
        ```shell
        $ tidepy GSE78220.self_subtract.zip -o GSE78220.txt -c Melanoma
        ```
        
        The output file `GSE78220.txt` has those columns: No benefits, Responder, TIDE, IFNG, MSI Score, CD274, CD8, CTL.flag, Dysfunction, Exclusion, MDSC, CAF, TAM M2, which are exactly the same with the result outputted from our website. 
        
        ```
        $ head GSE78220.txt
