IndexError: index out of bounds for axis 1

[shaynehansen]

Getting the error:
return self._RDMS_data[0:, channel_index]
IndexError: index 840 is out of bounds for axis 1 with size 840


The class RDMSDictionary is where the data is read in, and class Pdfs is where I am trying to access and get the IndexError.

Any help is greatly appreciated!
