problem with NCBI remap in genomic coordinates of SNP which arenot mapped

Question

[mnosrati669]

Hi, I'm starting out new in bioinformatics. I'm trying to convert SNPs with genomic coordinates in ovis aries 3.1 assembly to oar_v4.0. I used map file (Oar_v 3.1) for making bed file and then remaped this file by NCBI Remap based on oar_ v4.0 The problem is that SNP on chr0 dosenot remaped by NCBI Remap dose any body know how can I get genomic coordinates of SNP in Oar_ v4.0 which are mapped on chromosome 0 in first assembly?

thanks a lot for any idea
