There are disagreements between formats for linked-read data. Haplotagging thinks linked-read barcodes and FASTQ files should look one way, stLFR a different way, and TELLseq yet another. Djinn lets you convert to a standard format, convert between these FASTQ formats, barcode styles, etc. It also provides a convenient method to upload linked-read data to NCBI that preserves barcode information.
