When yоu аre finished with this prоgrаm (аnd ready tо move on to the extra credit program, if you want), please copy and paste “Question 2 of the Proctored Final Exam is complete and ready for grading.” in the text box for this question. Program 2: Find Shared Variants If multiple people carry the same DNA variant as well as the same phenotype (for example, a disease), it may be that this variant caused the phenotype. Your task is to search multiple VCF files and identify the variants that are shared across all of those VCF files. For a variant to be considered shared, the exact same variant line must appear in all the files and the value in the FILTER column must be PASS in all the files. As an illustration, suppose you were looking at VCF_file1.vcf and VCF_file2.vcf (shown above). You would want to find the following three shared variants:chr1 3675 A G PASS chr1 3789 T G PASS chr11 55 T C PASS These variants are shared because the exact same line appears in both input files and the value in the FILTER column is PASS in both files. A fourth variant (chr7, 787879) appears in both files. However, in the first file, the FILTER value is NO PASS, so this variant does not count as a shared variant. Write a Python script that uses sys.argv to accept the following five arguments: The name of the mother's VCF file. The name of the father's VCF file. The name of the daughter's VCF file. The name of the son's VCF file. The name of an output file that your code will need to create. Your Python script should search the four VCF files and identify the variants that are shared across all four individuals (mother, father, daughter, son). After identifying the shared variants, write the data to the specified output file. This should be a tab-delimited file with four columns that correspond to the CHR, POS, REF, and VAR columns in the VCF files. The output file should look the same as the modified VCF files used in this final, except there should be no metadata lines or header lines, all output should be uppercase, and it should not include the FILTER column. You should write the variants to output.txt in the same order they appear in the first input file. (In the example below, that is the order the variants appear in VCF_file1.vcf.) All columns in the output file are tab-delimited. For example, if the server were to execute your code (using only the two VCF files, VCF_file1.vcf and VCF_file2.vcf, for brevity): python studentcode.py VCF_file1.vcf VCF_file2.vcf output.txt Expected output (tab-delimited and all uppercase): CHR1 3675 A G CHR1 3789 T G CHR11 55 T C You may assume we will always give you exactly four VCF files.
