Characteristics of SynChro, MCScanX and i-ADHoRe synteny blocks for three pairwise comparisons.

The execution time (in minutes) indicates the time used for homolog identification and for synteny block reconstruction (for SynChro, these two steps are not really separable because reconstruction of synteny blocks implies the identification of additional non-RBH homologs by blastp). The number of syntenic homologs represents the total number of homology relationships in the synteny blocks. The numbers between brackets indicate the number of homology relationships when only one relationship per gene per synteny block is allowed (i.e. removing the homology relationships corresponding to tandemly duplicated genes within a given synteny block). Note that for MCScanX these 2 values are identical because the program was run with the option which prevents MCScanX to detect tandemly duplicated genes within a given synteny block.
