vcf.Reader() in Python doesn't read my VCF

Question

[Najla]

I was working on a building a GUI with wxPython and wanted to import a VCF file

with open(file_path, 'r') as file:
                vcf_reader = vcf.Reader(file)
                for record in vcf_reader:
                    # Access the fields of each VCF record as needed
                    chrom = record.CHROM
                    pos = record.POS
                    ref = record.REF
                    alt = record.ALT
                    qual = record.QUAL

however I got this error

SyntaxError: One of the FILTER lines is malformed: ##FILTER=All filters passed  

even though I check the header in the vcf file and it seems correct

##fileformat=VCFv4.1
##fileDate=20221003
##phasing=unphased
##source=VariantAnnotation 1.40.0
##FILTER=<ID=PASS,Description="All filters passed">
##FORMAT=<ID=AD,Number=2,Type=Integer,Description="Allelic depths (number of reads in each observed allele)">
##FORMAT=<ID=DP,Number=1,Type=Integer,Description="Total read depth">
##FORMAT=<ID=FT,Number=1,Type=String,Description="Variant filters"> 

Does anyone know why is this happening and how to fix this issue? Thanks!

Have you tried to check all the lines having the word "FILTER"? You might have another FILTER line in your header not compliant.

grep FILTER input.vcf
