It's indeed working replacing data with data.buffer
I will look into your issue.

The code should work fine in node or browser. Try with one of the test datasets and if you still have issues post the full stack trace.

The dicom file used is the one provided in your examples/data folder.

Stacktrace is here

I tested with data.buffer and it appears to work. Can you confirm. I did run into [this issue](https://github.com/dcmjs-org/dcmjs/issues/319}. If you are working on nodejs could you provide a PR to fix that?
