ChannelIndex parent of ImageSequence

[JuliaSprenger]

The current ImageSequence implementation is not listing channel_Index as a parent object or attribute

python-neo/neo/core/imagesequence.py

Line 89 in 593aff3

_single_parent_objects = ("Segment",)

python-neo/neo/core/imagesequence.py

Line 90 in 593aff3

_single_parent_attrs = ("segment",)

However, indirectly this attribute is generated by inherited BaseSignal methods, e.g.

python-neo/neo/core/basesignal.py

Line 83 in 593aff3

self.channel_index = getattr(obj, 'channel_index', None)

leading to the channel_index set.
@apdavison Is there a reason for not explicitely listing ChannelIndex as a parent of ImageSequence?

[apdavison]

Is it causing problems? Since ChannelIndex will disappear in v0.10.0, does this need to be addressed?

[JuliaSprenger]

No, it is just an inconsistency I came across when writing a ChannelIndex & Unit -> View & Group conversion (apdavison#3). We could either fix it for this release, but I think it might be coming with a number of follow-up changes required across the project.
