Hello everyone, I'm handling self-made VCF files and I need to bgzip and tabix -p them ibn order to use some vcf-tools perl scripts. When I apply the tabiz command: Tabix -p vcf file1.vcf.gz the following error appears:

[ti_index_core] the file out of order at line 8

I had previous errors because I had an extra withespace at the end of each line which I removed using:

sed -e 's/ $//' file1.vcf

I have to say that the VCF file is all tab separated.

So, there are the first 20 lines of my vcf file:

##fileformat=VCFv4.1
