Trace results from ParallABEL for NARAC data. Trace results from Type1_parall_by_SNPs, Type2_parall_by_individuals, Type3_parall_by_pairs_of_individuals, and Type4_parall_by_pairs_of_SNPs for NARAC data. When Type1_parall_by_SNPs is executed by the GenABEL mlreg function, Type2_parall_by_individuals is executed by the GenABEL hom function, Type3_parall_by_pairs_of_individuals is executed by the GenABEL ibs function, and Type4_parall_by_pairs_of_SNPs is executed by the GenABEL r2fast function. If there is only one processor, then the data is analysed using GenABEL. If there is more than one processor, the data is analysed using ParallABEL package.
