1. DicomID isn't currently supported, this needs loading a string directly, but there's an implicit typecast to double that I wasn't able to find. I tried using regex matching to extract the value but that failed too.
2. Figure out how to best integrate pre-processing steps (right now they're distributed across python and R, mostly because I'm more comfortable with Python) - https://gist.github.com/Aa-Aanegola/a14bdfedcc5aa1459d76f977e75713e0
