Comparing NCBI36 and HuRef , Getting the contigs of HuRef ?

[bioiion]

I'm recently comparing two assembled genomes, NCBI36 and HuRef.
There are datasets of insertion, deletion and duplication of HuRef compared to NCBI36.

For example,
insertion variation on chr7:13030 bp
duplication variation on chr7:557764-558731 bp
(genomic coordinates of NCBI36)

1. Is there any way I can get the inserted sequence from HuRef?
2. And genomic coordinate of HuRef where the inserted sequence is located?
3. And If I know a genomic coordinate of HuRef, How can I get the contigs/sequences which were used to assemble HuRef genome?

Thanks in advance.
