Overview of HiCAT. a Generation of the block list and similarity matrix. b Mining of higher-order repeats (HORs). \({t}_{d}\) represents the similarity threshold in the current iteration. \({t}_{d+1}\) represents the similarity threshold in the next iteration. \({t}_{min}\) is the minimum similarity threshold. \(step\) is the threshold increase for each iteration. For example, \({t}_{0}=94\%\) and \({t}_{1}= {t}_{0}+0.5\%=94.5\%\). \({S}_{i,j}\)is the similarity between block \(i\) and block \(j\). HTRM: hierarchical tandem repeat mining. Colored rectangles in the monomer sequence represent monomers
