Step 2: ⌨️ Coding

• Modify src/MatchKits.php ✓ 4c52c4e Edit

Modify src/MatchKits.php with contents: Refactor MatchKits class:

<original_code>
class MatchKits {
private $kitsData = [];
private $matchedData;

public function loadKitsData($kitPaths) {
    foreach ($kitPaths as $path) {
        $this->kitsData[] = new Dna\Snps\SNPs($path);
    }
}

public function matchKits() {
    $this->matchedData = []; // Initialize matched data array
    foreach ($this->kit1Data->getSnps() as $snp1) {
        foreach ($this->kit2Data->getSnps() as $snp2) {
            if ($snp1['pos'] == $snp2['pos'] && $snp1['genotype'] == $snp2['genotype']) {
                $this->matchedData[] = $snp1; // Add matching SNP to matched data
            }
        }
    }
}

public function visualizeMatchedData($format) {
    $visualization = new Visualization();
    $visualization->plot_chromosomes($this->matchedData, "matched_data." . $format, "Matched SNP Data", "Build", $format);
}

}
</original_code>

<new_code>
/**

• Matches SNP data between DNA kits
  /
  class MatchKits
  {
  /*

  • @var SNPs[] The DNA kit data to match
    */
    private array $kitsData = [];

  /**

  • @var array The matched SNP data
    */
    private array $matchedData = [];

  /**

  • Match the loaded DNA kits
    */
    public function matchKits(): void
    {
    $this->matchedData = []; // Reset matched data

    foreach ($this->kitsData[0]->getSnps() as $snp1) {
    foreach ($this->kitsData[1]->getSnps() as $snp2) {
    if ($snp1['pos'] === $snp2['pos'] && $snp1['genotype'] === $snp2['genotype']) {
    $this->matchedData[] = $snp1;
    }
    }
    }
    }

  /**

  • @return array The matched SNP data
    */
    public function getMatchedData(): array
    {
    return $this->matchedData;
    }

  /**

  • Load DNA kit data
  • @param SNPs[] $kitsData The kit data to load
    */
    public function setKitsData(array $kitsData): void
    {
    $this->kitsData = $kitsData;
    }
    }
    </new_code>

• Create src/scripts/match_kits.php ✗ 4c52c4e Edit

Create src/scripts/match_kits.php with contents: Move the CLI specific code to a new script file:

<?php
require_once __DIR__ . '/../MatchKits.php';
require_once __DIR__ . '/../KitLoader.php'; 
require_once __DIR__ . '/../Visualization.php';

$loader = new KitLoader();

echo "Enter the number of kits to compare: ";
$numKits = trim(fgets(STDIN)); 

$kitPaths = [];
for ($i = 0; $i < $numKits; $i++) {
    echo "Enter file path for Kit " . ($i + 1) . ": ";
    $kitPaths[] = trim(fgets(STDIN));
}

$kitsData = $loader->loadKitsData($kitPaths);

$matcher = new MatchKits();
$matcher->setKitsData($kitsData);
$matcher->matchKits();

$visualization = new Visualization();
$matchedData = $matcher->getMatchedData();
$visualization->plotChromosomes($matchedData, "matched_data.png", "Matched SNP Data", "Build", "png");

echo "Matched data visualization has been generated.\n";

• Create src/KitLoader.php ✓ 4c52c4e Edit

Create src/KitLoader.php with contents: Create a new KitLoader class to handle loading DNA kit data:

<?php
namespace Dna\Snps;

/**
 * Loads DNA kit data from files
 */
class KitLoader
{
    /**
     * Load DNA kit data from the provided file paths
     *
     * @param string[] $kitPaths The file paths to load
     * @return SNPs[] The loaded DNA kit data  
     */
    public function loadKitsData(array $kitPaths): array
    {
        $kitsData = [];
        
        foreach ($kitPaths as $path) {
            $kitsData[] = new SNPs($path);
        }
        
        return $kitsData;
    }
}

• Modify src/Visualization.php ✓ 4c52c4e Edit

Modify src/Visualization.php with contents:

Update the Visualization code to follow PSR-12:

1. <original_code> matches the actual code from the file verbatim, so no changes are needed:
   <original_code>
   function plot_chromosomes($matchedData, $path, $title, $build, $format) {
   // Visualization code...
   }
   </original_code>

2. Update <new_code> block to convert the function to a class method as planned:
   <new_code>
   /**

• Generates visualizations of DNA data
  /
  class Visualization
  {
  /*
  • Plot the provided SNP data on a chromosome map
  • @param array $data The SNP data to plot
  • @param string $filename The filename for the generated plot
  • @param string $title The title for the plot
  • @param string $build The genome build version
  • @param string $format The image format for the plot
    */
    public function plotChromosomes(
    array $data,
    string $filename,
    string $title,
    string $build,
    string $format
    ): void {
    // Visualization code...
    }
    }
    </new_code>
