# # LDpred-2-Inf
# 
# In this notebook, we will use LDpred-2-Inf to calculate the Polygenic Risk Score (PRS).
# 
# **Note:** LDpred-2 needs to be installed using R.
# 
# We will use the same flow of the code, and when we have to invoke LDpred-2 functions, we will call the script using Python. When LDpred-2 finishes executions, results will be stored in the specific directories for each fold and will be retrieved in Python for further calculations.
# 
# ## Install LDpred-2
# 
# Install LDpred-2 using the following commands:
# 
# 1. Activate the conda Environment.
# 2. Type R
# 3. Run the following commands:
# 
# ```R
# install.packages("remotes")
# library(remotes)
# remotes::install_github("https://github.com/privefl/bigsnpr.git")
# ```
# 
# The content in this notebook has been taken from the [PRS Tutorial](https://choishingwan.github.io/PRS-Tutorial/ldpred/), [LDpred-2 Documentation](https://privefl.github.io/bigsnpr/articles/LDpred2.html), and [Polygenic Scores (PGS)](https://privefl.github.io/bigsnpr-extdoc/polygenic-scores-pgs.html).
# 
# Thanks to Florian Privé for creating one of the best documentations explaining each aspect of the calculation. We will be using LDpred-2 for cross-validation design and hyper-parameter optimization, and this tutorial complements the existing one.
# 
# 

# ## LDpred-2  Hyperparameters
# 
# ### Hyperparameters for LDpred-2  performed using PLINK
# 
# #### Pruning Parameters
# 
# Informs Plink that we wish to perform pruning with a window size of 200 variants, sliding across the genome with a step size of 50 variants at a time, and filter out any SNPs with LD \( r^2 \) higher than 0.25.
# 
# 
# ```python
# 1. p_window_size = [200]
# 2. p_slide_size = [50]
# 3. p_LD_threshold = [0.25]
# ```
# 
# #### Clumping Parameters
# 
# The P-value threshold for an SNP to be included. 1 means to include all SNPs for clumping. SNPs having \( r^2 \) higher than 0.1 with the index SNPs will be removed. SNPs within 200k of the index SNP are considered for clumping.
# 
# ```python
# 1. clump_p1 = [1]
# 2. clump_r2 = [0.1]
# 3. clump_kb = [200]
# ```
# #### PCA
# Pca also affects the results evident from the initial analysis; however, including more PCA overfits the model. 
# 
# ### Hyperparameters for LDpred-2 
#  
# 
# 
# #### Heritability
# 
# To calculate h2 using LDpred-2, we followed the [LDpred-2 tutorial](https://choishingwan.github.io/PRS-Tutorial/ldpred/).
# The code for this part is in R, as LDpred-2 is in R.
# 
# 1. Using SNPs from the HapMap as preferred by the authors. The name in the code is `LDpred-2_hapmap`.
# 2. Using all the SNPs. The name in the code is `LDpred-2_full`.
# 
# This approach is computationally expensive, as the correlation between all the SNPs in a specific chromosome is being calculated.
# 
# ### LDpred-2 Models
# 
# Each model has its own set of hyperparameters, so first, we will generate those hyperparameters for those models and call them when invoking LDpred-2.
# 
# Use the following R code to know more about the hyperparameters:
# - `help(snp_ldpred2_inf)`
# - `help(snp_ldpred2_grid)`
# - `help(snp_ldpred2_auto)`
# - `help(snp_lassosum2)`
# 
# #### 1. LDpred2-inf: Infinitesimal Model
# 
# No Hyperparameters
# 
# #### 2. LDpred2(-grid): Grid of Models
# 
# Each model has its own set of parameters:
# - `burn_in = 100`
# - `num_iter = 10`
# - `p = c(1e-4, 1e-5)`
# - `h2 = c(0.1, 0.2)`
# - `sparse = c(FALSE, TRUE)`
# 
# #### 3. LDpred2-auto: Automatic Model
# 
# - `burn_in = 100`
# - `num_iter = 100`
# - `sparse = c(FALSE, TRUE)`
# - `alpha_bounds = c(1, 0.5)`
# - `use_MLE = c(FALSE, TRUE)`
# - `p = c(1e-4, 1e-5)`
# - `shrink_corr = 0.7`
# - `allow_jump_sign = c(FALSE, TRUE)`
# 
# #### 4. lassosum2: Grid of Models
# 
# - `lambda = c(0.001, 0.01, 0.1, 1)`
# - `delta = 30`
# 
# We will execute the code for each mkodel seperatly.
# 

# ### GWAS file processing for LDpred-2.
# When the effect size relates to disease risk and is thus given as an odds ratio (OR) rather than BETA (for continuous traits), the PRS is computed as a product of ORs. To simplify this calculation, take the natural logarithm of the OR so that the PRS can be computed using summation instead.

# ### Define Hyperparameters
# 
# Define hyperparameters to be optimized and set initial values.
# 
# ### Extract Valid SNPs from Clumped File
# 
# For Windows, download `gwak`, and for Linux, the `awk` command is sufficient. For Windows, `GWAK` is required. You can download it from [here](https://sourceforge.net/projects/gnuwin32/). Get it and place it in the same directory.
# 
# 
# ### Execution Path
# 
# At this stage, we have the genotype training data `newtrainfilename = "train_data.QC"` and genotype test data `newtestfilename = "test_data.QC"`.
# 
# We modified the following variables:
# 
# 1. `filedirec = "SampleData1"` or `filedirec = sys.argv[1]`
# 2. `foldnumber = "0"` or `foldnumber = sys.argv[2]` for HPC.
# 
# Only these two variables can be modified to execute the code for specific data and specific folds. Though the code can be executed separately for each fold on HPC and separately for each dataset, it is recommended to execute it for multiple diseases and one fold at a time.
# Here’s the corrected text in Markdown format:
# 
#  
# ### P-values
# 
# PRS calculation relies on P-values. SNPs with low P-values, indicating a high degree of association with a specific trait, are considered for calculation.
# 
# You can modify the code below to consider a specific set of P-values and save the file in the same format.
# 
# We considered the following parameters:
# 
# - **Minimum P-value**: `1e-10`
# - **Maximum P-value**: `1.0`
# - **Minimum exponent**: `10`  (Minimum P-value in exponent)
# - **Number of intervals**: `100`  (Number of intervals to be considered)
# 
# The code generates an array of logarithmically spaced P-values:
# 
# ```python
# import numpy as np
# import os
# 
# minimumpvalue = 10  # Minimum exponent for P-values
# numberofintervals = 100  # Number of intervals to be considered
# 
# allpvalues = np.logspace(-minimumpvalue, 0, numberofintervals, endpoint=True)  # Generating an array of logarithmically spaced P-values
# 
# print("Minimum P-value:", allpvalues[0])
# print("Maximum P-value:", allpvalues[-1])
# 
# count = 1
# with open(os.path.join(folddirec, 'range_list'), 'w') as file:
#     for value in allpvalues:
#         file.write(f'pv_{value} 0 {value}\n')  # Writing range information to the 'range_list' file
#         count += 1
# 
# pvaluefile = os.path.join(folddirec, 'range_list')
# ```
# 
# In this code:
# - `minimumpvalue` defines the minimum exponent for P-values.
# - `numberofintervals` specifies how many intervals to consider.
# - `allpvalues` generates an array of P-values spaced logarithmically.
# - The script writes these P-values to a file named `range_list` in the specified directory.

# ## Results
# 
# ### 1. **Reporting Based on Best Training Performance:**
#    - One can report the results based on the best performance of the training data. For example, if for a specific combination of hyperparameters, the training performance is high, report the corresponding test performance.
#    - Example code:
#      ```python
#      df = divided_result.sort_values(by='Train_best_model', ascending=False)
#      print(df.iloc[0].to_markdown())
#      ```
#  
# #### Binary Phenotypes Result Analysis
# 
# You can find the performance quality for binary phenotype using the following template:
# 
# ![PerformanceBinary](PerformanceBinary.PNG)
#  
# 
# This figure shows the 8 different scenarios that can exist in the results, and the following table explains each scenario.
# 
#  
# 
# We classified performance based on the following table:
# 
# | Performance Level      | Range    |
# |------------------------|----------|
# | **Low Performance**    | 0 to 0.5 |
# | **Moderate Performance** | 0.6 to 0.7 |
# | **High Performance**   | 0.8 to 1 |
# 
#  
# You can match the performance based on the following scenarios:
# 
# | Scenario                     | What's Happening                                                                                                   | Implication                                                                                             |
# |------------------------------|--------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|
# | **High Test, High Train**     | The model performs well on both training and test datasets, effectively learning the underlying patterns.          | The model is well-tuned, generalizes well, and makes accurate predictions on both datasets.              |
# | **High Test, Moderate Train** | The model generalizes well but may not be fully optimized on training data, missing some underlying patterns.      | The model is fairly robust but may benefit from further tuning or more training to improve its learning. |
# | **High Test, Low Train**      | An unusual scenario, potentially indicating data leakage or overestimation of test performance.                    | The model’s performance is likely unreliable; investigate potential data issues or random noise.        |
# | **Moderate Test, High Train** | The model fits the training data well but doesn’t generalize as effectively, capturing only some test patterns.     | The model is slightly overfitting; adjustments may be needed to improve generalization on unseen data.   |
# | **Moderate Test, Moderate Train** | The model shows balanced but moderate performance on both datasets, capturing some patterns but missing others. | The model is moderately fitting; further improvements could be made in both training and generalization. |
# | **Moderate Test, Low Train**  | The model underperforms on training data and doesn’t generalize well, leading to moderate test performance.         | The model may need more complexity, additional features, or better training to improve on both datasets. |
# | **Low Test, High Train**      | The model overfits the training data, performing poorly on the test set.                                           | The model doesn’t generalize well; simplifying the model or using regularization may help reduce overfitting. |
# | **Low Test, Low Train**       | The model performs poorly on both training and test datasets, failing to learn the data patterns effectively.      | The model is underfitting; it may need more complexity, additional features, or more data to improve performance. |
# 
# ##### Recommendations for Publishing Results
# 
# When publishing results, scenarios with moderate train and moderate test performance can be used for complex phenotypes or diseases. However, results showing high train and moderate test, high train and high test, and moderate train and high test are recommended.
# 
# For most phenotypes, results typically fall in the moderate train and moderate test performance category.
# 
#  
# #### Continuous Phenotypes Result Analysis
# 
# You can find the performance quality for continuous phenotypes using the following template:
# 
# ![PerformanceContinous](PerformanceContinous.PNG)

# | **Moderate Performance** | 0.3 to 0.7 |
# | **High Performance**   | 0.8 to 1     |

# ##### Recommendations for Publishing Results
# 
# When publishing results, scenarios with moderate train and moderate test performance can be used for complex phenotypes or diseases. However, results showing high train and moderate test, high train and high test, and moderate train and high test are recommended.
# 
# For most continuous phenotypes, results typically fall in the moderate train and moderate test performance category.
# 
# 
# 
# 
# 
# 
#  
# 
# ### 2. **Reporting Generalized Performance:**
#    - One can also report the generalized performance by calculating the difference between the training and test performance, and the sum of the test and training performance. Report the result or hyperparameter combination for which the sum is high and the difference is minimal.
#    - Example code:
#      ```python
#      df = divided_result.copy()
#      df['Difference'] = abs(df['Train_best_model'] - df['Test_best_model'])
#      df['Sum'] = df['Train_best_model'] + df['Test_best_model']
# 
#      sorted_df = df.sort_values(by=['Sum', 'Difference'], ascending=[False, True])
#      print(sorted_df.iloc[0].to_markdown())
#      ```
# 
# 
# ### 3. **Reporting Hyperparameters Affecting Test and Train Performance:**
#    - Find the hyperparameters that have more than one unique value and calculate their correlation with the following columns to understand how they are affecting the performance of train and test sets:
#      - `Train_null_model`
#      - `Train_pure_prs`
#      - `Train_best_model`
#      - `Test_pure_prs`
#      - `Test_null_model`
#      - `Test_best_model`
# 
# 
# 
# ### 4. Other Analysis
# 1. Once you have the results, you can find how hyperparameters affect the model performance.
# 2. Analysis, like overfitting and underfitting, can be performed as well.
# 3. The way you are going to report the results can vary.
# 4. Results can be visualized, and other patterns in the data can be explored.
