Description
One (for sure) or even three (possible) header files contained in the MGH/MF Waveform Database are faulty and therefore can't be read with the wfdb python library
- mgh025's header is missing a digit in its year (e.g. 199 instead of 1991?)
- mgh061's as well as mgh127's headers are missing a correct declaration of the number of samples per signal field in their record line. E.g. in both headers the signal has a length of 0 samples - which of course can be a correct declaration but should there really be files in an official database missing a value in that field? [furthermore/alternatively could be an incompatibility of the python package]

Research direction
Start by inspecting the linked mgh025.hea, mgh061.hea, and mgh127.hea files and reproducing the failures with the wfdb Python library. Determine whether the year and sample-count fields are faulty or reflect a library incompatibility; done when the diagnosis is confirmed and the affected headers or compatibility behavior is corrected.
