Hi,
I have saved a GRanges object and now after updating GenomicRanges I have trouble loading it again:

> gr
GRanges with 2581 ranges and 4 elementMetadata values
Error in validObject(.Object) : 
  invalid class "GRanges" object: slots in class definition but not in object: "seqinfo"
> 

This data is very important, so is there a way to restore this object?

Thank you for your help.
