TABIX on generic tab file

[mstagliamonte]

Hi, Everybody,

I have a 1-based, tab-delimited file with some annotations, which I would like to use with bcftools annotate on a vcf file.
The fields are:
CHROM, START, END, FEATURE, and a couple of more columns I am not really interested in.

According to samtools 1.x instructions, the tab file needs to be bgzipped and indexed with TABIX.

This is how I am proceeding:

 bgzip myfile.tab # everything's fine so far

and then:

tabix -s 1 -b 2 -e 3 myfile.tab.gz

And that's when I get into trouble; the error I get is:
[E::get_intv] failed to parse TBX_GENERIC, was wrong -p [type] used?
The offending line was: "CHROM FROM TO WIDTH STRAND FEATURE"

[E::get_intv] failed to parse TBX_GENERIC, was wrong -p [type] used?
The offending line was: "CHROM  FROM    TO      WIDTH   STRAND  FEATURE"

I am a bit puzzled, what am I doing wrong?

Thanks for your help,
Max

use #CHROM FROM TO WIDTH STRAND FEATURE to mark it as a header line or just remove the line entirely.

Thanks! I realize now it was a bit of a naive question, I'll do it straight away

Best,
Max
