Vidjil add‐on for MRD quantification of samples processed using the EuroClonality‐NGS protocol

Abstract

Assessment of minimal residual disease in acute lymphoblastic leukemia by immune repertoire NGS requires spiking CDR3 sequences at known quantities into the patient's sample. Recently, the EuroClonality‐NGS group released one of the most comprehensive protocols for this purpose. ARResT/Interrogate is a closed‐source software for processing these NGS libraries, developed by this same group. Vidjil, an open‐source alternative, currently cannot handle libraries prepared using this protocol. Here, we present a Vidjil add‐on to solve this issue. EuroClonality‐NGS prepared samples analyzed with Vidjil and ARResT/Interrogate were highly concordant (r = 0.998) and presented low error (root‐mean‐square error, RMSE = 0.112).
