TSS coordinates from Ensembl Biomart

Question

[ZheFrench]

When you use biomart you can get 1-based TSS start coordinate. If you want to transform this coordinate to 0-based format you need to remove 1, whatever the strand is , right ?

If strand + , TSS is chr11 48488717 coordinate in biomart. If you want bed format, it will be :

chr11 48488716 48488717 name signalValue +

If strand - , TSS is chr11 64879712 coordinate in biomart. If you want bed format, it will be :

chr11 64879711 64879712 signalValue 0 -
