Marker Synonyms ReportBLAST Analysis: This analysis uses BLAST to find markers within the Triticeae Toolbox database that have similar sequence. A marker is identified as a match if either
1. the sequence homology is > 99% and alignment length is > 95% of the query sequence.
2. there is only one mismatch and the alignment length is > 95% of the query sequence.
The analysis uses blastn v2.2.28+ with the following arguments "-outfmt 6 -dust no -word_size 16 -task megablast -evalue 1e-08". The top level page gives a summary of the matching markers for each experiment. Select the experiment link to give the second level of a detailed comparison for one experiment. Select the "match to other markers" to get the list of individual BLAST results. Reference: BLAST Help
Included Data: GBS markers that are already anchored to the reference genome (labeled as WCSS1) where not analyzed. The BLAST database included all markers loaded in T3 as or April 26, 2015.
Interpretation: The blast hits between a marker and itself have been removed. When an experiment is compared to itself you will still see a small number of matches because the markers may match within the experiment. Before 2013 the markers were checked for sequence matches when imported and if a match was found a synonym was created. For the large GBS experiments the marker sequence was not checked for sequence matches to the existing database of markers.
