Can you please help me with this. I am working with trying to do:
vcf.fn <- "sequences_covid_SRA_april21_36genomes_sequence_aligned.trimmed.fasta.vcf" snpgdsVCF2GDS(vcf.fn, "sarscov2.gds", method="biallelic.only")
and I got this error:
No sample in the VCF file!
Which could be the reasons for this error? I check the file and it seems ok. Thank you in advance.
