FATAL ERROR on phASER

Question

[Shani]

Hello everyone, I'm encountering issues regarding my vcf file when running phASER. I've tried indexing it both with tabix (tabix -p vcf file.vcf.gz) and bcftools (bcftools index -t file.vcf.gz) and both processes resulted with a file.vcf.gz.tbi file type. in spite of that, each time I try to run phASER (with either of them), i keep getting this error; "FATAL ERROR: VCF file is not tabix indexed" has anyone encountered a similar difficulty and has insights regarding possible solutions?

thanks in advance :)
