Hi, I tried to run snpEff for annotating variants with the following command:

java -Xmx4g -jar snpEff.jar GRCh37.75 -interval ~/ngs/reference.fasta ~/Desktop/somsnp.vcf > snp.ann.vcf

I am getting the following result in the output vcf file:

#CHROM  POS ID  REF ALT QUAL    FILTER  INFO    FORMAT  NORMAL  TUMOR

The reference file used for alignment and variant calling is a fasta file extracted from hg19 genome sequence with custom bed file using bedtools getfasta. Please help me with this error

Where is the error?

The reference file used for alignment and variant calling is a fasta file extracted from hg19 genome sequence with custom bed file using bedtools getfasta.

That is not recommended. You should align against the full genome.

You may have different contig names between your VCF and annotation, e.g., "chr1" versus just "1"
