MUMmer 4.0.0.beta3

In this release we disabled openMP in suffix array construction because it was causing system errors when user ran multiple nucmer processes in the same shell. We also added delta2vcf script:

delta2vcf < file.delta > file.vcf

The script converts delta file to a vcf file, detailing all substitutions and indels in the reference sequence with respect to the query sequence. This is useful for comparing two different assemblies of the same organism, assemblies of two different individuals from the same spcies, and looking for haplotype differences in haplotype resolved assemblies.
