Description

I'm trying to use vcfpy yo convert a CSV file into VCF the script : import pandas as pd
import vcfpy
import sys

def csv_to_vcf(csv_file, vcf_file):

# read CSV file using pandas
df = pd.read_csv(csv_file)
# read vcf file
reader = vcfpy.Reader.from_path(vcf_file)
# create a new VCF file
vcf_writer = vcfpy.Writer.from_path(vcf_file,reader.header)

# add the header information to the VCF file


# loop through rows in the CSV file
for i, row in df.iterrows():
    # create a new record for the VCF file
    record = vcfpy.Record(
        CHROM=row['#CHROM'],
        POS=row['POS'],
        ID=".",
        REF=row['REF'],
        ALT=".",
        QUAL=".",
        FILTER=".",
        INFO=".",
        FORMAT=[])
    
    chr = row['#CHROM']
    pos = int(row['POS'])
    ref = row['REF']
    alt = row['ALT']

    chr='chr'+str(chr)
    if chr == 'chrMT':
        chr = 'chrM'
    try:
        fetched = reader.fetch(record.CHROM,pos-5,pos+5)
    
    except:
        fetched = '.|.'
    for fet in fetched:
    # add the record to the VCF file
        vcf_writer.write_record(fet)
            



# close the VCF file
vcf_writer.close()

if name == "main":
csv_file = sys.argv[1]
vcf_file = sys.argv[2]
csv_to_vcf(csv_file,vcf_file)

What I Did

python csv_to_vcf.py Cmpd_Hetro_Bathc1_morethan10test.csv results_table.DVD.vcf

where the Cmpd is the CSV file and the VCF file already has a header.

If there was a crash, please include the traceback here.
