The resultant map bears a close resemblance to a conventional physiographic map of Poland; differences can be attributed to geological and paleogeographical input used in drawing the conventional map but not utilized by the mapping algorithm.
After removing incorrectly assigned markers and markers reported suspicious by the mapping algorithm in MSTmap, 21 linkage groups that correspond to the total number of hexaploid wheat chromosomes were obtained.
This deletion is characterized by a loss of heterozygosity of variants measured relative to the reference, a cluster of 11 paired end reads (target length 500 bases) whose mates map in excess of 11kb from one another, as well as 15 reads that span the junction of the deletion that were soft trimmed by the mapping algorithm.
If the genome of the sample is very different from the reference sequence, not only a much higher number of variants will be detected, but many reads will not be mapped altogether due to a limited number of mismatches allowed by the mapping algorithm.
Instead of computing the exact values of symbol a posteriori probabilities P(d(p)(n) = ϑ∣Y(n), H) provided by the MAP algorithms, in the proposed sub-optimal detector, these probabilities are calculated in an approximated way.
where x ^ t, u, m = arg max x t, u, m ≤ y t, u p ( x t, u, m | y t, r, m ) (5). is the imputation resulting from the m th CG, a bounded optimization problem which can be solved by the MAP algorithm as in the correlation-based approach.
To exclude false positives introduced by the sequencing technology or the mapping algorithm used, results were confirmed with Sanger sequencing.
Finally, we were able to remove alignment artefacts of the mapping algorithm by manual curation; primarily, some two-nucleotide transversions were wrongly called.
