checkHaplotypeSyntax

Checks if alleles in a haplotype have correct syntax and an appropriate number of fields.

Processes amino acid alignments produced by the 'IPD-IMGT/HLA (Immuno Polymorphism-ImMunoGeneTics/Human Leukocyte Antigen) Database' to identify user-defined amino acid residue motifs shared across HLA alleles, HLA alleles, or HLA haplotypes, and calculates frequencies based on HLA allele frequency data. 'SSHAARP' (Searching Shared HLA Amino Acid Residue Prevalence) uses 'Generic Mapping Tools (GMT)' software and the 'GMT' R package to generate global frequency heat maps that illustrate the distribution of each user-defined map around the globe. 'SSHAARP' analyzes the allele frequency data described by Solberg et al. (2008) <doi:10.1016/j.humimm.2008.05.001>, a global set of 497 population samples from 185 published datasets, representing 66,800 individuals total. Users may also specify their own datasets, but file conventions must follow the prebundled Solberg dataset, or the mock haplotype dataset.

checkHaplotypeSyntax function

<dl><dt>haplotype</dt>
<dd>A haplotype where allele names are written in the IPD-IMGT/HLA Database format, and have 1-4 fields. Alleles in haplotypes must be delimited by "~".</dd>
<dt>filename</dt>
<dd>The full file path of the user specified dataset if the user wishes to use their own file, or pre-bundled mock haplotype dataset. User provided datasets must be a .dat, .txt, or.csv file, and must conform to the structure and format of the mock haplotype dataset bundled with the package.</dd></dl>
