Hard coded int vs variable int produce different slicing results in brain object


Slicing a brain object with an int variable produces an empty brain object (no elecs, no data).
Slicing a brain object with an int variable wrapped in a list returns the correct brain object.
Slicing a brain object with an int returns the correct brain object.

__get_item__ method calls get_slice

which seems to wrap the int in a list


the left pane shows a debugging breakpoint ("import ipdb; ipdb.set_trace()") but on the right pane you can see when the slicing is run, it doesn't trigger the breakpoint so it must be bypassing the method

Start in supereeg/brain.py at Brain.__getitem__ around line 325 and follow its call to get_slice; compare slicing with a literal int, an int variable, and a one-item list. Done means the variable-int form returns the same populated brain object as the equivalent forms, preserving electrodes and data.
