The command corrects a DNA sequencing error of cell barcoding containing RT primer sets for Quartz-Seq2 which one of a high throughput single-cell RNA-sequencing [1]. The cell barcodes of Quartz-Seq2 are designed such that the minimum Sequence–Levenshtein distance between two sequences should be greater than 5, which leads to the correction of two nucleotides of mismatch, insertion, and deletion in sequence reads [2]. The program can correct cell barcode if sequence error occurs.
