[Bioc-devel] VcfFile and VcfFileList

[Valerie Obenchain]

Hi Robert,

Have you seen TabixFile and TabixFileList? Both scanVcf() and readVcf() 
have methods for TabixFile.

 > showMethods("readVcf")
Function: readVcf (package VariantAnnotation)
file="character", genome="character", param="missing"
file="character", genome="character", param="ScanVcfParam"
file="character", genome="missing", param="missing"
file="TabixFile", genome="character", param="GRanges"
file="TabixFile", genome="character", param="GRangesList"
file="TabixFile", genome="character", param="missing"
file="TabixFile", genome="character", param="RangedData"
file="TabixFile", genome="character", param="RangesList"
file="TabixFile", genome="character", param="ScanVcfParam"

Does this fit your need/use case?

Valerie
