Open-source sequence development tools are often simulation-focused or acquisition-focused. The ability to simulate and acquire from the same sequence file would help speed up method development. In this work, we present an open-source Python tool, py2jemris, which converts arbitrary Pulseq files to JEMRIS simulation format with a zero-footprint Google Colab notebook. A dual simulation/acquisition experiment using the same sequence file was performed to demonstrate the development pipeline. The conversion and simulation time were recorded and evaluated.
