 - The current version of the `PrintDQ` tool is intended to be run over 1 run at a time. As the clustering tools may take some time to compile, the processing time of this toolchain may take several minutes (for a ~100 part file run) to ~1 hour (~thousands of part files) depending on how many part files exist.
+- Find [here](https://github.com/S81D/PrintDQ/tree/main) a set of scripts to run this toolchain on the grid and produce data quality plots from the outputted .csv files.
