Original Variant Identifiers Are Destroyed #120

To make it easy to compare variants before and after imputation, it would be great if the server didn't destroy the identifiers in the ID column. For instance, the input file might look like:

#CHROM    POS              ID      REF     ALT
    10 133243  GSA-rs76243118        G       A

but in the imputation server's output file:

#CHROM    POS                  ID      REF     ALT
chr10   87303     chr10:87303:G:A        G       A

It is not easy to match these without resorting to the coordinates and reversing the lift-over that was done from hg19 to hg38.
