• Add read length: both submitter entered and inferred (median length)
• Add calculated read counts: both raw and assigned
• Add median TIN
• Output multiqc json (for future use)
• Convert gene symbols to Entrez ID: for data-hub convenience (use version specific metadata - added to references)
• Create bash script to initiate parallel replicate runs from study RID
• Change consistence tests for assigned reads exact match to being within +/- 1/100,000 of expected
