[Vcftools-help] tabix

[Al-Hasani, H. <hoo...@iz...>]

Dear vcftools team,

I hope you kindly help me with a tabix problem (knowing it is not a vcftool) ...

I'm trying to extract CEU SNPs, after downloading ALL.chr${i}.phase1_release_v3.20101123.snps_indels_svs.genotypes.vcf.gz 
I'm using this command to index the file:

tabix -fh /work/.../1kG/ALL.chr${i}.phase1_release_v3.20101123.snps_indels_svs.genotypes.vcf.gz ${i}:1-$chrm_size > ALL.chr${i}.vcf

then to filter and extract the SNPs

vcftools --vcf ALL.chr${i}.vcf --plink-tped --keep CEU.samples.list --remove-indels --min-alleles 2 --max-alleles 2 --maf 0.01 --max-maf 0.99 --out chr${i}

before running any of these commands I made sure to add the tool's paths
export PATH=${PATH}:/work/.../vcftools_0.1.9/bin
export PATH=${PATH}:/work/.../vcftools_0.1.9/perl
export PERL5LIB=/work/.../vcftools_0.1.9/perl:$PERL5LIB
export PATH=${PATH}:/work/.../tabix-0.2.6/

However, I'm getting the error [tabix] failed to load the index file
The strange thing, if I tried it like this 
tabix -fh ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/release/20110521/ALL.chr${i}.phase... I don't get any error.

Could you please help? I already lost time on trying over and over (same paths, complete paths, no paths, different parameters...)

Thank you very much in advance!
