Hi all,

I have problems trying to indexing my VCF file with tabix. 

Fist, I transformed my gzipped VCF to a bgzipped one

“zcat myvariants.vcf.gz | bgzip -c > myvariants.vcf.bgzip.gz”

Then, I ran tabix as follows,

“tabix -p vcf myvariants.bgzip.vcf"

And everything was fine. But the problem is that when a listed the chromosomes, 
several were missing. Provided that my genome is highly repetitive, I have an 
assembly with a lot of scaffolds, 829971, but only 296354 were listed with 
tabix -l flag.   

has tabix a limit on the number of chromosomes or scaffolds that can be indexed?

Thanks in advance.
