From: LSCplus: a fast solution for improving long read accuracy by short read alignment
HC results of LSC and LSCplus. LSC records the compressed positions and corresponding HC counts. LSCplus records all of the ‘HC’ counts corresponding to the compressed sequence. In LSCplus, “AAACGGTTCTTA” will be compressed to “ACGTCTA”, and the HC Counts Array for the compressed read is HC = [3,1,2,2,1,2,1]. The index array will be [0,1,2,3,4,5,6], which represents the position numbers of HC count in the array as well as the position numbers of bases in the compressed read; once the HC array is constructed, the indexes are set, such that the index array is not needed
