For each predicted stem MSARI considers all 7 nt blocks which are aligned to each other (to produce potential common stem loops); each such alignment is considered to be of interest as a function of its composition, especially the number of covarying mutations it involves.
Although within the central heterochromatin a limited set of RH sequence blocks could still be aligned to DM superscaffold 33 and positioned by a single FISH anchor, a credible ordering of the remaining large volume of RH and DM sequence blocks in this region was not possible.
Anti-hostile vehicle street furniture was put on those streets, and side streets were aligned to block direct lines of vehicle entry.
However, in many practical scenarios, the non-zero elements are aligned to blocks, meaning that they appear in regions.
Only a very few markers identified among the 26 accessions of the three species could be aligned to the ancestral block G of Brassicaceae, and also only a few G blocks have been identified in Brassica genomes previously [ 2, 6– 9, 13, 15, 16, 29, 43] (Additional file 3).
A total of 659 marker sequences in the SY-PM genetic map could be aligned to the ancestral block.
For example, in the initial assembly, Contig10 was aligned to two genomic blocks on rice chromosome 1, separated by over 35 Mb.
Orthologous gene pairs between X and Y were aligned to create contiguous blocks until no more orthologs were identified within the threshold range of the intergenic distances in both genomes (Fig. 1e).
The longest block in terms of aligned physical length was BnaWAIT_A_20 in A04 which was aligned to 10.9 Mb of Arabidopsis chromosome 2 (Arabidopsis blocks C2B and C2C).
Step 4. Fragments defined as the same block were aligned, including an extra 10 bp either side to check for possible block extension, and their consensus sequence was defined allowing for a given number of mismatches (initially two).
