Allele Name Translation Tool (ANTT)
The ANTT is a .Net application that translates HLA allele names between IPD-IMGT/HLA Database release versions, as well as user-defined nomenclatures. Described by Mack and Hollenbach. 2010:

Bridging Immunogenomic Data Analysis Workflow Gaps (BIGDAWG)
BIGDAWG is an R package automates the case-control analysis of highly polymorphic genetic data (e.g., HLA and KIR). Described by Pappas et. al. 2015: and

phased or unphased linkage disequilibrium (pould) 
Pould is an R package that calculates four LD measures (D’, Wn, Wa/b and Wb/a) for pairs of genetic loci, allows phase to be estimated via EM methods, or taken as submitted, and generates heat maps of LD values for all locus pairs. Described by Osoegawa et al., 2019a and 2019b: doi:10.1016/j.humimm.2019.01.010 and doi:10.1016/j.humimm.2019.05.018
