Tabix on bed file

[bluesmartini]

OK it works now, the problem was the automatic change of tabulations with 4 spaces with my f** text editor

Hello,

I'm trying to use tabix on a bed file and it seems that tabix is unable to parse my file.
Here is my file :

chr7    1000    5000    name1   1   +
chr7    15000   25000   name3   4   +
chr7    35000   75000   name4   8   +
chr7    57373   987412  name5   16  -

my commands are :
$ bgzip example_sort.bed
$ tabix -p bed example_sort.bed.gz

and the outputs are :

[E::get_intv] failed to parse TBX_GENERIC, was wrong -p [type] used?
The offending line was: "chr7    1000    5000    name1   1   +"
[E::get_intv] failed to parse TBX_GENERIC, was wrong -p [type] used?
The offending line was: "chr7    15000   25000   name3   4   +"
[E::hts_idx_push] Unsorted positions on sequence #4653157: 1 followed by 0
tbx_index_build failed: example_sort.bed.gz

Any ideas would be appreciated!
Thanks
