Workflow: expression values from HPC RGD workflow (processed before workflow 2.1); computed sex, strand and library prep added by RGD attribute backfill 1.0 (2026-10-21) using the workflow 2.1 rules. Note: ComputedSex is called from sex-gene expression: R = (Xist TPM + 1) / (median TPM of Uty, Ddx3y, Kdm5d and Eif2s3y + 1); R >= 10 is called F, R <= 1 is called M, and other values, or samples where Xist and the Y-gene median are both below 1 TPM, are Undetermined. Females express Xist and males the Y-linked genes. Sry is reported but not used in the calculation. XYRatio (X:Y read coverage) is shown for reference only. Agreement compares ComputedSex with InputSex (submitted to GEO).
