PhD candidate Sehrish Kanwal gave a talk at the University of Melbourne CIS Doctoral Colloquium on Reproducibility of Genomics Workflows. This covered the different approaches taken to realise large-scale genomic workflows across the Cloud – from fully programmatic approaches such as CPipe, semi-declarative approaches such as Galaxy, through to fully declarative approaches such as CWL. The trade offs and most importantly the challenges raised by the different approaches for repeatability of science were identified. Great stuff Sehrish!
