# Sequenom was a geneotyping process in which four 96 well parent plates were
# transferred onto a single 384 well plate prior to genotyping.
# The four plates were interlaced such that:
# A1: Plate 1, well A1
# A2: Plate 2, well A1
# B1: Plate 3, well A1
# B2: Plate 4, well A1
# The remaining methods allow legacy Sequenom plates to get viewed.
